●
●
In order to make the monitor safe grounding, the hospital must provide the power
socket with complete wire under voltage, zero line and protective grounding in
accordance with national standard. Or the hospital bears all consequences.
To ensure patient safty, verify the divice and accessories can function safely and normally
before use.
Only qualified accessories can be used for the monitor.
The ECG cable uses five-lead or three-lead cable, and cannot be connected to other signal
terminals.
In order to avoid losing time for diagnosis and treatment, please configure adequate
alarm settings according to different conditions of each patient (for detailed setting
methods, refer to ALARM SETTINGS in CHAPTER 5).
When using this monitor, the F-type application section cannot be connected to other
conductivity or ground.
When using the electrosurgery unit during the monitoring, the loop of the electrosurgery
unit shall be properly connected to prevent from burning, even the life risk.
The monitor must be operated on battery power if the external wiring is in doubt.
When various equipments are connected to the same patient, pay attention to the danger
of leakage current overlap.
The Monitor has no defibrillation synchronization, so it cannot be connected to the
synchronization defibrillation instrument.

FUNCTION
The G3 Multi-Parameter Patient Monitor can be used to monitor the major parameters such as
electrocardiogram (ECG), body temperature (TEMP), impedance respiration (RESP), oxygen
saturation (SpO2), invasive blood pressure (IBP), noninvasive blood pressure (NIBP) and CO2
(EtCO2 and FiCO2). It integrates the parameter measurement, display and record export as a whole,
which forms a compact and portable monitor.
The monitor is capable of monitoring the following parameters:
■
Electrocardiogram (ECG): heart rate (HR), 7 (or 3) leads ECG waveforms and ST segment
analysis.
■
Noninvasive blood pressure (NIBP): systolic pressure (SYS), diastolic pressure (DIA) and
mean arterial pressure (MAP).
■
Body temperature (TEMP): temperature of channel 1 (T1), temperature of channel 2 (T2)
and temperature difference between the two channels (△T).
■
Pulse oxygen saturation (SpO2): SpO2, pulse rate (PR) and SpO2 plethysmogram.
■
Respiration: respiration rate (RR) and respiration (impedance respiration or nasal tube
respiration) waveform.
■
Invasive blood pressure (IBP): 2 channels of IBP waveforms, systolic pressure (SYS),
diastolic pressure (DIA) and mean pressure (MEAN).
■
Carbon dioxide (CO2): end-tidal carbon dioxide (EtCO2), fractional inspiratory carbon
dioxide (FiCO2) and CO2 waveform.

WARNING
●
●
Keep the battery out of the reach of children.
Only use the battery specified by the manufacturer.
BATTERY MAINTENANCE
Conditioning a Battery
A battery should be conditioned before it is used for the first time. A battery conditioning cycle is
one uninterrupted discharge of the battery. Batteries should be conditioned regularly to maintain
their useful life. Condition a battery once when it is used or stored for two months, or when its run
time becomes noticeably shorter.
To condition a battery, follow this procedure:
1. Disconnect the monitor from the patient and stop all monitoring or measuring.
2. Insert the battery in need of conditioning in the battery slot of the monitor.
3. Apply AC power to the monitor and allow the battery to charge uninterrupted for 10 hours.
4. Remove AC power and allow the monitor to run from the battery until it shuts off.
5. Apply AC power again to the monitor and allow the battery to charge uninterrupted for 10
hours.
6. This battery is now conditioned and the monitor can be returned to work.
Checking a Battery
The performance of a rechargeable battery may deteriorate over time. To check the performance of a
battery, follow this procedure:
1. Disconnect the monitor from the patient and stop all monitoring or measuring.
2. Apply AC power to the monitor and allow the battery to charge
uninterrupted for 10 hours.
32
3.
Remove AC power and allow the monitor to run from the battery until it
shuts off.
4. The operating time of battery reflects its performance directly.
Please replace the battery or contact with the maintenance personnel if its
operating time is significantly lower than the specified time.
NOTE
●
●
Life expectancy of a battery depends on how frequent and how long it is used. For a
properly maintained and stored lead-acid or lithium ion battery, its life expectancy is
about 2 or 3 years respectively. For more aggressive use models, life expectancy can be
less. We recommend replacing lead acid batteries every 2 years and lithium ion batteries
every 3 years.
The battery might be damaged or malfunctioned if its operating time is too short after
being fully charged. The operating time depends on the configuration and operation. For
example, measuring NIBP more frequently will also shorten the operating time.
BATTERY RECYCLING
When a battery has visual signs of damage, or no longer holds a charge, it
should be replaced. Remove the old battery from the monitor and recycle it
properly. To dispose of the batteries, follow local laws for proper disposal.
WARNING
●
Do not disassemble batteries, or dispose of them in fire, or cause them to short circuit.
They may ignite, explode, leak or heat up, causing personal injury.

ALARMS
The monitor gives audible or visual alarms to indicate the medical staff, when a
vital sign of the patient appears abnormal, or mechanical or electrical problems
occur to the monitor.
ALARM CATEGORIES
The alarms are divided into two categories:
Physiological alarms
A physiological alarm either indicates that a monitored physiological parameter
is out of specified limit or indicates an abnormal patient condition.
Prompt information
Besides the physiological alarm, the monitor also displays the information related to the system. For
example, if a parameter module is turned on but the required leads or sensor
are not connected, the monitor will prompt accordingly, such as “Lead Off” in
the ECG and RESP channels, “Sensor Off” in the PLETH channel, or “No Cuff”
under the NIBP parameter, etc. Prompt information is usually displayed in the
channels area. But the prompt information relating to NIBP is displayed under
51
the NIBP value in the parameters area.
ALARM MODES
When an alarm occurs, the monitor raises the user’s attention by the following
audible or visual indications.
Visual alarms
When a measured physiological parameter value exceeds the preset alarm limit, the alarm
indicator on the front panel flashes in red once a second.
Audible alarms
When a measured physiological parameter value exceeds the preset alarm limit, the
monitor phonates a triple-beep tone each three seconds to prompt users.

CHAPTER 12:
ECG MONITORING
OVERVIEW
This Monitor adopts 5-lead (or 3-lead) ECG cable to collect the ECG signal from the patient, and it
can simultaneously display seven (or three) leads of ECG signal. ECG channel displayed on the top
part of the screen is the major channel of the ECG signal, and its lead is called the major lead. The
Monitor calculates the heart rate value and controls the gain (if set in automatic mode) according to
the data of the main lead. All leads adopt the same gain and same measurement mode. The Monitor
can separately check whether the connection of a lead has fallen off, and display the promt
information in corresponding channel.
1.Measurement of ECG
The electro-chemical activity of “Excitable cell” will produce physiological current
to cardiac muscle before the mechanical shrinkage of heart, the close movement
current produced by the process of heart exciting will flow within the human body and
transport to all parts, it results in the different voltage on the different surface of body.
The clinic Electrocardiography is to record the voltage difference real time.

2.1 Figure
1.1Electrode of ECG
Current within human body is conducted by hydronium, while it’s by electron in
metal conductor, so there should be a conversion medium to convert the hydronium
current to electron current, which will help realize the necessary connection between
the human body and patient monitor, electrode is to play the role to realize the
transformation. The widely used electrode for clinic monitoring is Ag—Ag.Cl disposable
electrode.
1.2. ECG leads
The definition of lead is the periodically changing waveform with heart beating
caused by the voltage between two or more than two surface parts of human body.
One lead waveform can only reflect one aspect of the heart movement since the
74
heart is solid, so it’s necessary to record several leads waveforms to reflect the
complete movement of heart from different respects during the process of diagnosing.
Below table is the definition for the different leads of ECG:

Our patient monitor adopts five leads ECG cable to collect signal of patient’s ECG.
It displays synchronously seven ECG waveforms. The fixed channel of ECG displayed
on the upper position is the main one of ECG signal, we call the ECG lead which the
main channel choose “main lead”, patient monitor calculate the value of heart rate and
control the gain based on it (if them monitor is set to model of “Auto gain”). We have the
same gain control and test mode to all leads, the patient monitor is able to check
whether the corresponding electrode of leads is fall off and display it on screen.
2.Monitoring of ECG electrode
It can get mostly twelve selectable ECG leads if use five leads ECG cable to monitor patient’s
ECG, the ECG waveform of this lead of patient will be displayed when the leads is set as valid.
The ECG cable includes two parts: main stem cable which connected to patient monitor and
Lead cable electrode which connected to patients, usually the ECG cable has five electrodes, please
note below items when place the electrodes to patients:
1） How to choose and use electrodes
It usually chooses Ag-AgCL one-off electrode, please make sure the electrodes are during the
period of validity. It will result in inaccurate data if use the incompetent electrodes.
2） Pretreatment of skin
It’s necessary to pre-treat the skin of patient to ensure the good touch between electrode and
patient since the skin is not a good conductor.
(1) Clean the skin with soap and water instead of aether and alcohol since the later two will
increase the resistance of skin.
(2) Shave off the fur of body where to place the electrode if necessary.
(3) Rub skin to increase the blood floor of capillary vessel of organization and get ride of the
horn and grease.
75
(4) Place the electrode to patient, please apply conductive cream before the electrode is put to
patient if the electrode do not have conductive cream.
(5) Connect the electrode and ECG cable.
(6) Make sure the connection of patient monitor power.
ECG MONITORING
In order to monitor the patient’s ECG, we use a five-electrode ECG cable by which we can get more
than 12 selective ECG leads. If a lead is effective, the corresponding waveform will be displayed in
the channels area.
The ECG cable includes two parts: the main cable connecting the Monitor and the electrode lead line
connecting the patient.
PREPARATION

Select electrode
Generally, the electrode for monitoring is disposable electrode made from Ag-AgCl (silver silver chloride). But before use, you shall confirm that the electrode is within the valid date. If
the unqualified electrode is used, it will lead to inaccurate monitoring result.
Skin pretreatment
Because the skin is not a good conductor, if you want to gain good contact between the skin and
the electrode, before installing the electrode, you shall carry out skin pretreatment at first.
(1) If necessary, shave hair from skin at choosen site.
(2) Rub the skin to accelerate the blood flow in the blood capillary of organs and remove the
horny layer and greases of the skin.
(3) Thoroughly cleanse the site with mild soap and water solution, but do not use the aether
or pure alcohol, because it will increase skin resistance.
(4) Dry the skin completely before applying the electrodes.
Attach the ECG lead to the electrodes prior to placement.
Place the electrode on the patient. If the conductive ointment is not applied to the
electrodes, apply it before the placement.
Connect the electrode lead to the patient cable.
Confirm the Monitor is powered on and is ready for monitoring.
ELECTRODE PLACEMENT
(1)
For the placement of the five–lead ECG electrode, refer to the figure as shown in Figure 12-1.

●
The sign name and color of the electrode shown above is American standard, while inside
the brackets ( ) is European standard.
White (right arm or RA) electrode: near the right shoulder, directly below the
clavicle.
■
Black (left arm or LA) electrode: near the left shoulder, directly below the clavicle.
■
Green (right leg or RL) electrode: on the right abdomen.
■
Red (left leg or LL) electrode: on the left abdomen.
■
Brown (chest or V) electrode: on the chest.
■
(2)
When using five leads, attach the chest (V) electrode to one of the
following positions indicated in Figure 12-2:
Figure 12-2 Positions of Chest Electrode
In order to accurately install and monitor the "V" lead, it is very important to determine the
fourth rib position, which is determined according to the first rib position. Because of the
patients’ different bodily forms, it is difficult to accurately feel out the first rib position. At
first, feel out the small protruding body called the "Lewis angle", where the breastbone
diaphysis and manubrium sterni joint. Then determine the second rib position, the protuberant
section of the breastbone indicates the joint of the second rib, right under here is the position
of the second rib position, from the chest to feel down until the fourth rib position is
determined.
Attach the chest (V) electrode to one of the following positions indicated in
Figure 12-2:
77
V1: On the 4th intercostal space at the right sterna margin.
■
V2: On the 4th intercostal space at the left sterna margin.
■
V3: Midway between V2 and V4 electrodes.
■
V4: On the 5th intercostal space at the left clavicular line.
■
V5: On the left anterior axillary line, horizontal with V4 electrode.
■
V6: On the left middle axillary line, horizontal with V4 electrode.
■
V3R-V7R: On the right side of the chest in positions corresponding to
those on the left.
■
VE: Over the xiphoid.
When attaching the chest electrode to the back of a patient, place it at
one of the following sites:
■
V7: On the 5th intercostal space at the left posterior axillary line of the
back.
■
V7R: On the 5th intercostal space at the right posterior axillary line of
the back.

Electrode placement for pacemaker patient
The pacemaker lead can pick up the best ECG waveform from the pacemaker patient. At this
time, the electrode is usually placed on the mammillary line, the white and black electrodes
are placed as shown in Figure 12-3.
Red (green)
Black (yellow)
White (red)

Electrode placement for surgical patient
Electrode placement during surgery is dependent on the type of surgery
being performed. For example, with open chest surgery, the electrodes
might be placed laterally on the chest or on the back. In the operating
room, artifact can sometimes affect the ECG waveform due to the use of
electrosurgery equipment. To help reduce this, place the electrodes on the
right and left shoulders, the right and left sides near the stomach, and
place the chest lead on the left side at mid-chest. Avoid placing the
electrodes on the upper arms. This will cause the ECG waveform to be too
small.
NOTE
●
Select the place with stable ECG signal or little inference of skeleton activities to place the
78
electrodes.
WARNING
●
●
●
●
●
●
●
In order to ensure the patient’s safety, all leads shall be connected to the patient.
The electrode shall be fixed properly to ensure the reliable contact of the conductor with
skin.
Interference from a non-grounded instrument near the patient and ESU interference can
cause inaccuracy of the ECG waveform.
When using Electrosurgery equipment, never place the ECG electrodes near the
grounding plate of the Electrosurgery device. This will cause a great deal of interference
with the ECG signal. The patient leads should be placed in a position that is equal
distance from the Electrosurgery electrotome and the grounding plate to avoid burns to
the patient.
Always dispose of, or recycle electrodes properly to prevent from environment
contamination.
Verify the lead fault detection prior to the start of monitoring. Unplug the ECG cable
from the ECG connector, the flashing error message “Lead Off” will be displayed in the
corresponding ECG channel.
Skin irritation may result from the continuous application of the ECG electrodes. These
should be checked each day. If there is an indication of excess skin irritation, replace the
electrodes or change the location of the electrodes every 24 hours.

■
Select this button, the main lead switches among I, II, III, aVR, aVL, aVF and V. In order to get
accurate heart rate and gain control performance, the doctor shall select the lead of large range
and little noise as the main lead.
In order to avoid emerging leads repeatedly, when the lead in the current channel is switched,
the leads in the other channels will be changed automatically.
Gain Mode
Select this button, the gain mode switches between AUTO and MANUAL modes.
Gain means the magnification times for the ECG waveform signal. This monitor has five
magnification times that are ×1/4, ×1/2, ×1, ×2 and ×4. The ×1 is one time magnification,
under which the range ⑦ of the scale ⑧ at the left side of the ECG waveform is 1mV. Then
under the condition of ×2 magnification, the range ⑦ of the scale ⑧ is 0.5mV, and so on.
Detailed data refers to the following table:

Under 1 ECG and Huge Digit display format, the length of the scale ⑧ is 10mm. The
waveform of 10mm diaplayed under ×1 magnification times means the ECG signal is 1mV,
under ×2 means 0.5mV.
NOTE
●
All leads including the main lead and other leads adopt the same gain.
This Monitor provides two methods to regulate the ECG waveform range:
●
AUTO mode: Under the AUTO mode, according to the main lead waveform data, the
Monitor will automatically regulate the gain to amplify the ECG waveform of the main
lead without the distortion as possible. The defect of this mode is slow regulation speed.
●
MANUAL mode: Under this mode, the Monitor doesn’t regulate the ECG gain
automatically. At this time, the ECG gain is regulated via the Adjust Gain button. The
feature of this mode is fast response that the waveform will change immediately after the
gain is regulated, and the waveform can be amplified to a distortion status to display.
■
Adjust Gain
Manually regulates the ECG gain. After selecting this button, regulate the gain via the rotating
mouse. Rotate counterclockwise, the gain and waveform range become smaller, while rotate
clockwise, the gain and waveform range become larger. After the accomplishment of the
regulation, press down the rotating mouse again to exit the gain adjusting mode.
■
Mode
The Mode means the filter bandwidth of the ECG channel. The monitor has three modes:
diagnosis (DIA), monitoring (MON) and operation (OPR). Under the DIA mode, the filter
bandwidth is the widest, and the detailed information of the ECG signal can be got. The more
detailed information is helpful to more accurately judge the status of the ECG signal. But when
the importation of the detailed information, the environmental noise, such as HF electrotome,
80
may be imported too. The noise mixes with the real ECG signal, so that the ECG signal cannot
be distinguished. In order to adapt to the noise interference situation, the Monitor also provides
two measurement modes, namely the MON mode and the OPR mode. Under these two modes,
narrower bandwidth is adopted to measure and gain smoother signal. The user can make
choices according to the exact situations, and the comparing data are as followings:
Mode

automatically.
●
ECG: HR is always calculated from ECG.
●
SpO2: If the ECG signal is seriously interfered, you can select SpO2, which means PR will
be derived from PLETH waveform. In this case, “PR (SpO2)” is displayed instead of
“ECG (I, II, etc.)” while the PR reading is displayed below. The monitor activates pulse

CHAPTER 13:
RESP MONITORING
OVERVIEW
This Monitor measures out the respiration movement waveform by the ECG cable with the
impedance method. This respiration movement waveform is used to calculate the respiration rate and
analyse the respiration status.
The Monitor can measure three lead respiratory waveforms such as I, II or III lead, of which, the II
lead is generally used. Because of the different signal strength, the Monitor provides AUTO and
MANUAL modes to adjust the gain. The respiratory waveform will be clear and without distortion if
an appropriate gain is adopted.
ELECTRODE PLACEMENT
The impedance respiration method of this Monitor is to monitor the patient’s respiration by the
impedance variation between the two electrocardiogram electrodes of I, II or III lead. Since the
same electrodes are used for ECG and RESP monitoring, the electrode
placement is very important. Some patients, due to their clinical condition,
expand their chest laterally, causing a negative intrathoracic pressure. In these
cases it is better to place the two electrodes used for RESP monitoring laterally
in the right axillary and left lateral chest areas, at the maximum point of the
breathing movement, to optimize the respiratory waveform.
NOTE
●
●
●
RESP monitoring is not recommended on very active patients, because it will cause false
alarms.
Place the red and white electrodes diagonally to optimize the respiration waveform.
Try to avoid placing the electrodes so the liver area and the ventricles of the heart are in
path between the electrodes used for respiration, to avoid cardiac artifact to overlay on
the ECG. This is particularly important when monitoring neonate patients.

MONITORING INTERFACE
The RESP monitoring displays a RESP waveform in channels area and the measured respiration
rate value in parameters area.
RESP CHANNEL
Principal of impedance respiration monitoring
The movement of the thorax in the moment of the respiration will cause the
variation of the human body’s impedance, the range of the variation is about 0.1 ～3Ω,
G3 Monitor immits the human body a safe electric current which is 0.5 ～5mA by using
two electrode of the ECGⅡ lead with the 20K ～ 100KΩHZ carrier frequency sinusoidal
constant current, and then mesures out the difference of respiration impendace from
electrode LL—RA . This difference of the respiration impedance shows the dynamic
waveform of respiration
Using the impedance respiration method, G3 Monitor can measure out the human body
respiration movement waveform by using the electrocardiogram lead line, and this
respiration movement waveform can be used to the calculation of the human body
respiration rate and the analyse of the human body respiration status.
The G3 Monitor measure three lead respiration waveforms according to the selection
such as I, II, III, the II lead is generally used. Because of the different signal strength,
the Monitor provides two kinds of gain adjustment functions : automatic adjustment and
manual adjustment, it can make the respiration waveform clear and without distortion by
adopting appropriate gain.
The electrode connection
The impedance respiration method of this Monitor is to monitor the patient’s respiration
by the impedance variation between the two electrocardiogram electrodes. The
respiration monitoring is realized via the electrocardiogram I, II or III lead and their
86
corresponding electrodes, so no additional electrodes are required, and the installation
of the electrode is very important. For some patient, because of their clinical situation,
the horizontal expansion of the thoracic cage leads to the negativity thoracic cage
internal pressure, under this situation, it is better to put the two respiration electrodes at
the central line of the right armpit or the most active area on the left side of the thoracic
cage when breathing, so that the optimum respiration wave is gained.
We suggest installing five lead electrodes for the respiration monitoring, as shown in
Figure 3.4
Notice
①The respiration monitoring is not recommended to be used on the patient
who will move or be moved a lot, because it will lead to mis-alarm.
②In order to obtain optimum respiration wave, the white and the red
electrodes shall be installled catercorner. Avoid putting the liver and the
ventricle on connecting line, which can avoid the false difference
produced by the heart coverage or pulsation blood flow, this is very
important in the using for neonate.

CHAPTER 15:
NIBP MONITORING
OVERVIEW
The non-invasive blood pressure (NIBP) module measures blood pressure using the
oscillometric method. This monitor can be applied to adult, pediatric and neonate patients. Three
measurements are available: manual, auto and continuous. Each mode displays the
systolic pressure (SYS), mean arterial pressure (MAP) and diastolic pressure (DIA).
■ Manual: Pressing the NIBP key on the front panel starts a NIBP measurement.
■ Auto: The NIBP measurement is conducted automatically at a preset interval.
■ Continuous: The NIBP measurement is performed as many times as possible
in five minutes.
Blood Pressure Measurement Principle
NIBP measurement adopts vibration method. The principle is to charge air to blood
pressure cuff to the degree that arteries are pressed completely and the blood flowing is
blocked. And while the cuff is deflated gradually, the arteries are in the process of utter
90
blocking, gradual loosing and unobstructing. In this process the artery pressure
pulsation will generate air oscillating waves in the cuff. Theoretic arithmetic and
experiments indicates that oscillating waves have defined correspondence with artery
systolic blood pressure, mean blood pressure, and diastolic blood pressure. Hence
systolic blood pressure, mean blood pressure, and diastolic blood pressure can be
measured by analyzing measurement results and pressure oscillating waves in the cuff.

Pulse waveform
When the blood pressure measurement process starts up, the Monitor charges the air
into the blood pressure cuff, the human body blood pressure, including the systolic
blood pressure, diastolic blood pressure and mean pressure are measured out via the
sensors, a measurement process is about 40 seconds.
There are three start-up methods for blood pressure measurement, one is manual
measurement mode, the other is automatic measurement mode, and the third is
consecutive measurement mode.

Measurement
1. Korotkoff Sound Method, widely-adopted in clinics, is similar to vibration method. But there are
many coherent defects in Korotkoff Sound Method. It primarily relies on the coordination between
man’s vision and hearing, thus the method is rather subjective and unduplicated. Therefore the
results by Korotkoff Sound Method can not be applied to evaluate the results by vibration method.
2. Human arterial blood pressure is a changeable physiological parameter, related
with the patient’s emotion, psychological change, posture and position during the
measurement. So it should be considered in measurement and evaluation.
3. The vibration measurement bases on the oscillating waves in cuff, so the
oscillation from the outside and the movement of the patient’s arm will affect the
measurement results. The serious consequence is the failure in the measurement. It
needs measuring again.
91
 The noninvasive blood pressure (NIBP) measurement adopts the succussion;
 It is applicable to adult, pediatric and neonate.
 The measurement mode: manual, automatic and consecutive. Each mode displays
systolic blood pressure, mean pressure and diastolic blood pressure.
MONITORING PROCEDURE
To perform NIBP measurement on a patient, follow the procedure as below:
1. Power on the monitor.
2. Check the patient type. If the patient type is incorrect, select a correct
patient type in Patient Information dialog box.
3. Plug the air hose in the NIBP cuff connector of the monitor.
4. Apply a cuff of proper size to the upper arm or the leg of the patient.
5. Connect the cuff with the air hose.
6. Press the NIBP key on the front panel to start the NIBP measurement.
CUFF SELECTION AND PLACEMENT
1.
2.
3.
4.
5.
Identify the patient limb circumference.
Select appropriate cuff; limb circumference is identified on each cuff.
Verify the cuff is completely deflated; place cuff around extremity being
used and make sure the marking φ matches artery location.
Verify the cuff is not wrapped too tightly around the limb. Excessive
tightness may cause discoloration or ischemia of the extremities.
Make sure that the cuff edge falls within the range of the <-> mark. If it
does not, use a larger or smaller cuff that will fit better.
NOTE
●
●
The width of the cuff should be either 40% of the limb circumference (50% for neonates)
or 2/3 of the upper arm length. The inflatable part of the cuff should be long enough to
circle 50-80% of the limb. The wrong size cuff can cause erroneous readings. If the cuff
size is in question, use a larger cuff.
The limb chosen for taking the measurement should be placed at
the same level as the patient's heart. If this is not possible, use the
following method to correct the measurement result:
92
If the cuff is placed higher than the heart level, add 0.75mmHg
(0.10 kPa) for each centimeter of difference, or 1.9mmHg (0.25kPa)
for each inch of difference.
 If it is placed lower than the heart level, deduct 0.75 mmHg
(0.10 kPa) for each centimeter of difference, or 1.9mmHg (0.25kPa)
for each inch of difference.
If you are in doubt about the accuracy of any reading(s), check the patient's vital signs
by an alternative method before checking the function of the monitor.

●
WARNING
●
●
●
●
●
●
●
●
Use only the specified accessories for monitoring, or it will lead to the malfunction of the
Monitor.
You must not perform NIBP measurements on patients with sickle-cell disease or under
any condition where the skin is damaged or expected to be damaged.
For a thrombasthemia patient, it is important to determine whether measurement of the
blood pressure shall be done automatically.
Ensure that the setting is correctly made when performing measurements on children.
Incorrect patient type setting may cause a danger to the patient because adult blood
pressure level is higher than children.
Before the measurement, you shall confirm your configuration is suitable to the patient
(adult, pediatric or neonate).
Do not apply the cuff to a limb that has an intravenous infusion or catheter in place. This
could cause tissue damage around the catheter when infusion is slowed or blocked during
cuff inflation.
Auto non-invasive blood pressure measurements performed in long intervals may incur
ischemia and neuropathy in the limb wearing the cuff. When monitoring a patient,
examine the extremities of the limb frequently for normal color, warmth and sensitivity. If
any abnormality is observed, change the position of the cuff on the patient or stop the
blood pressure measurements immediately.
Make sure the air tubing connecting the blood pressure monitor is not blocked, twisted, or
tangled.
MEASUREMENT LIMITATIONS
Non-invasive blood pressure measurement uses the oscillometric method of
measurement. The monitor detects the regular arterial pressure pulse. In some
circumstances when the patient's condition makes it difficult to detect this
pulse, the measurement becomes unreliable and the measurement time
increases. You should be aware that the following conditions could interfere with
93
the measurement, make the measurement unreliable, prolong the
measurement, or even make a measurement impossible.
■ Patient movement: E.g.The patient is moving, shivering or jerking.
■ Cardiac arrhythmia: E.g.The patient's cardiac arrhythmia has caused an
irregular heartbeat.
■ Heart-lung machine: E.g. Measurements will be impossible if the patient is
connected to a heart-lung machine.
■ Pressure changes: E.g.The patient's blood pressure is changing rapidly over the
period of time during which the arterial pressure pulses are being analyzed
to obtain the measurement.
■ Severe shock: E.g.If the patient is in severe shock or hypothermia, reduced
blood flow to the peripheries will cause reduced pulsation of the arteries.
■ Heart rate extremes: The monitor is unable to perform pressure measurements
at a heart rate of less than 15 bpm and greater than 300 bpm.

FUNCTIONS
The NIBP monitoring has two functions, one is NIBP measurement, and the other is the
95
venipuncture function.
NIBP MEASUREMENT
When the NIBP measurement starts, the Monitor inflates the air into the cuff, and the SYS, DIA and
MAP are measured out via the sensor. A measurement process lasts about 40 seconds.
There are three NIBP measurement modes, one is manual mode, the other is auto mode, and the
third is continuous mode.
Manual mode
Select the Auto Manual button in the NIBP menu, if word MANUAL is displayed at the position ⑨,
the manual mode is selected. In this mode, a NIBP measurement shall be started manually by
pressing the NIBP key on the front panel. Before manual NIBP measurement, the max cuff pressure
should be set to a proper value.
Auto mode
Select the Auto Manual button in the NIBP menu, if word AUTO is displayed at the position ⑨, the
auto mode is selected. In this mode, the monitor periodically starts the NIBP measurement
automatically at the preset time interval.
The auto mode has two statuses, one is the stay status. In this status, the clock at position ⑧ stays,
and the auto measurement has not been started yet. The other status is the running status. In this
status, the clock at position ⑧ runs, and the auto measurement has been started. The clock at
position ⑧ indicates how much time still remains for the next measurement.
In the stay status, press the NIBP key to start the auto measurement. At this time, the clock at
position ⑧ begins to run. Switching to the manual mode, then switching back to the auto mode can
stop the auto measurement. Pressing the NIBP key during the NIBP measurement can stop the
measurement and switch the running status to stay status.
Continuous mode
Selecting the Stat Test button in the NIBP menu starts a continuous measurement which is provided
for surgical or emergent patient. Its feature is that it continuously measures NIBP for five minutes
once it is started, and the measurement mode adopted is simpler than other modes. After five
minutes, the monitor restores to the status (auto or manual) before the continuous measurement.
NOTE

TEMP MONITORING
TEMPERATURE PROBE INSTALLATION
The monitor is able to use two temperature probes simultaneously. Attach the temperature probe to
the patient’s body where ought to be measured, to abtain two temperature values and the difference
between them.
If a disposable temperature probe is used, plug the temperature probe cable in
the temperature probe connector, and then connect the temperature probe with
the cable; if a reusable temperature probe is used, connect the temperature
probe with the temperature probe connector directly.
NOTE
●
The disposable temperature probe is for single patient use only.
WARNING
●
●
Be careful to avoid damaging the temperature probe and cable. When the temperature
probe and cable are not in use, shape them into a loose round. If the cable is tangled too
tightly or over-bent, mechanical damage may occur.
The calibration of the temperature measurement function is desired every year (or as
dictated by your Hospital Procedures Policy). If you need to calibrate the temperature
measurement function, contact the manufacturer.

CHAPTER 17:
SpO2 MONITORING
OVERVIEW
SpO2 measurement is based on two principles: Firstly, oxyhemoglobin and
deoxyhemoglobin differ in their absorption of red and infrared light. Secondly,
the volume of arterial blood in tissue changes during the pulse. A monitor
determines SpO2 (oxygen saturation) by passing red and infrared light into an
arteriolar bed and measuring changes in light absorption during the pulsatile
cycle. Red and infrared low-voltage light-emitting diodes (LEDs) in the sensor
serve as light sources, a photodiode serves as the photo detector.
Because oxyhemoglobin and deoxyhemoglobin differ in light absorption, the
amount of red and infrared light absorbed by blood is related to hemoglobin
oxygen saturation. To identify the oxygen saturation of arterial hemoglobin, the
monitor uses the pulsatile nature of arterial flow. During systole, a new pulse of
arterial blood enters the vascular bed, and the blood volume and light
absorption increase. During diastole, the blood volume and light absorption
reach their lowest point. The monitor bases its SpO 2 measurements on the
difference between maximum and minimum absorption (i.e., measurements at
systole and diastole). By doing so, it focuses on light absorption by pulsatile
arterial blood, eliminating the effects of nonpulsatile absorbers such as tissue,
bone, and venous blood.
The monitor determines SpO2 and pulse rate by passing two wavelengths of light, one red and one
infrared, through body tissue to a photodetector. During measurement, the signal strength resulting
from each light source depends on the color and thickness of the body tissue, the probe placement,
105
RED LED AND INFRARED LED
LIGHT SOURCES
the intensity of the light sources, and the absorption of the arterial and venous blood (including the
time varying effects of the pulse) in the body tissue (Refer to Figure 17-1).

The monitor processes these signals, separating the time invariant parameters (tissue thickness, skin
color, light intensity, and venous blood) from the time variant parameters (arterial volume and
SpO2) to identify the pulse rate and calculate oxygen saturation. Oxygen saturation calculations
can be performed because oxygen saturated blood predictably absorbs less red light than oxygen
depleted blood.
The monitor can be used under low perfusion with same accuracy as normal
condition.
The monitor measures the patient’s SpO2 and displays:
■ Pulse rate (PR) value in the parameters area.
■ PLETH waveform and pulse intensity (perfusion indicator) in the channels
area.
■ Oxygen saturation (SpO2 %) value in the parameters area.
As the following figure shows, the perfusion indicator (prorate with the pulse
intensity) is located on the left side of the PLETH waveform while the measured
SpO2 value on the right. The SpO2 value is displayed by percentage. Besides, the
SpO2 label in the parameters area allows you to access the SpO2 menu.

dilution chemicals.
ES (Electrosurgery) equipment wire and SpO2 cable must not be tangled up. Carefully
route patient cabling to reduce the possibility of patient entanglement or strangulation.
Do not use this instrument and the sensors during magnetic resonance imaging (MRI).
Induced current could potentially cause burns. The monitor may affect the MRI image,
and the MRI unit may affect the accuracy of the oximetry measurements.
Do not put the SpO2 sensor on the limb with arterial catheter or venous syringe.
Do not perform SpO2 monitoring and NIBP measurements on the same arm
simultaneously. Obstruction of blood flow during NIBP measurements may adversely
affect the reading of the SpO2 value.
Before performing the testing, check the sensor cable. After unplugging the SpO2 sensor
cable from the socket, the system shall display the flashing prompt information "Sensor
Off" above the PLETH waveform.
Prolonged and continuous monitoring may increase the risk of burns at the site of the
sensor. It is especially important to check the sensor placement, and ensure proper
attachment on neonates and patients of poor perfusion or skin sensitive to light. Check the
sensor location every 2–3 hours and move to another location if the skin deteriorates.
More frequent examinations may be required for different patients.
NOTE
●
Place the SpO2 sensor cable at the backside of the patient hand. Make sure the fingernail
is just opposite to the light emitted from the sensor.
MONITORING PROCEDURE
Follow the procedure as below:
1. Power on the monitor.
2. Attach the sensor to the proper site on the patient.
3. Plug the connector of the sensor extension cable into the SpO2 connector on
monitor.
The process of SpO2 plethysmogram measurement is generally the same. But
the SpO2 sensor selection and placement depend on the patient type. When
choosing a site for a sensor, refer to the directions for that sensor.
MEASUREMENT LIMITATIONS
If the accuracy of any measurement does not seem reasonable, first check the
patient’s vital signs by an alternate method. Then check the instrument for
proper function. Inaccurate measurements may be caused by:
■ Incorrect sensor application or use;
■ Placement of a sensor on the same extremity with a blood pressure cuff,
arterial catheter, or intravascular line;
■ Exposure to excessive illumination, such as surgical lamps (especially ones
with a xenon light source), bilirubin lamps, fluorescent lights, infrared
heating lamps, or direct sunlight (exposure to excessive illumination can be
107
corrected by covering the sensor with a dark material);
■ Excessive patient motion;
■ Venous pulsations;
■ Intravascular dyes such as indocyanine green or methylene blue;
■ Defibrillation;
Other physiological conditions or medical procedures that may interfere with
the monitor’s measurements include significant levels of dysfunctional
hemoglobin, low perfusion, and dark pigment.
Loss of pulse signal can occur in the following situations:
■ The sensor is too tight;
■ A blood pressure cuff is inflated on the same extremity as the one with a
SpO2 sensor attached;
■ There is arterial occlusion proximal to the sensor.
Select an appropriate sensor, apply it as directed, and observe all warnings and
cautions presented in the directions for use accompanying the sensor. Clean
and remove any substances such as nail polish from the application site.
Periodically check to ensure that the sensor remains properly positioned on the
patient.
If patient movement presents a problem, try one or more of the following
remedies to correct the problem.
■ Verify that the sensor is properly and securely applied.
■ Move the sensor to a less active site.

CHAPTER 18: IBP
MONITORING
IBP CHANNELS
The monitor provides two channels to measure the invasive blood pressure (IBP, including systolic,
diastolic and mean pressures), and displays two channels of waveforms and two parameters. The two
channels of waveforms are displayed in a same or different waveform area, differentiated by color.
When the two curves overlapped, the curve color will be the color of channel 2. The figure below is
the channels displayed in different waveform area:

① Label of channel 1: Selecting this label pops up the menu of channel 1.
② Label of channel 2: Selecting this label pops up the menu of channel 2.
③ Pressure axis: It is the pressure axis of the waveform displayed on its right side, shown as
below:
Maximum
0 mmHg
The bottom horizontal line indicates the location of zero pressure. If a curve dot is displayed higher
than this line, it means the pressure of this dot is positive; accordingly, the pressure of the dot, which
is lower than this line, is negative.
The top horizontal line indicates the maximum pressure of current display gain. The curve line
where its pressure is higher than the maximum pressure will be clipped and becomes a section of
horizontal line.
The height of the waveforms relates to the pressure. And the ratio between height and pressure is
specified. Maximum value and Minimum value are listed in the following table:
Maximum value on screen
Minimum value on screen

The monitor can automatically select a proper ratio according to the phase of the waveform. It also
provides a function to adjust the ratio manually. Here we call it two gain modes: Auto mode and
Manual mode.
④ Status message: Displayed above the waveform. All the possible status messages are listed in
the following table:

⑤
① IBP label of channel 1
② Systolic blood pressure (SYS)
③ Mean pressure (MEAN)
④ Indicates that this area displays the measured IBP values of channel 1.
⑤ Diastolic blood pressure (DIA)
IBP values can vary in the range from –60mmHg to 300mmHg. Values not in this range will be
displayed as invalid pressure, in the form of “---” or “--.-”.
But there are more reasons if these pressure values are displayed as invalid values, they are:
1. The actual pressure is not in the range from -60 mmHg to 300 mmHg.
2. The channel wasn’t zeroed.
3. The cable is disconnected or not connected firmly.
4. The channel is not calibrated properly.
5. In zero processing.
6. Monitor is starting.
The IBP unit is the same as the NIBP unit. See REGION SETTINGS in CHAPTER 4 for detailed
information.

MAINTENANCE AND CLEANING
WARNING
●
Before cleaning the transducer, make sure the transducer is disconnected from the
monitor, or the monitor is powered off and disconnected from AC power.
CLEANING OF IBP TRANSDUCER
After the IBP monitoring operation is completed, remove the tubing and the
dome from the transducer and wipe the transducer diaphragm with water. To
clean the transducer and the cable, wipe them using soap or the detergents
listed below:
■ Cetylcide
■ Wavicide-01
■ Wescodyne
■ Cidex
■ Lysol
■ Vesphene
Do not immerse the connector in any liquid. After cleaning, dry the transducer
thoroughly before storing. Slight discoloration or temporary increase of surface
115
stickiness of the cable should not be considered abnormal. If it is necessary to
remove the adhesive tape residue from the transducer cable, the double seal
tape remover is recommended; use the remover with special caution to
minimize the damage to the cable. Acetone, Alcohol, Ammonia and Chloroform,
or other strong solvents are not recommended because they are harmful to the
vinyl cabling if used for a long time.
NOTE
●
●
The disposable transducers or domes must not be reused.
To avoid contamination, the disposable transducers or domes must be reclaimed or
disposed of properly, complying with the local laws.
STERILIZATION
Chemical Solution Sterilization
After finishing the cleaning, select an effective sterilant for chemical solution
sterilization of the operating room equipment. Buffered glutaraldehyde (e.g.
Cidex or Hospisept) is recommended. Do not use quaternary cationic detergents
such as zephiran chloride. If the whole unit is to be sterilized, immerse the
transducer but not the electrical connector into the sterilant for the
recommended sterilizing period. Ensure that the dome has been removed. Then
rinse all transducer parts except the electrical connector with sterilized water or
saline. The transducer must be thoroughly dried before storing.
Gas Sterilization
For more complete asepsis, use gas sterilization. The transducer should be
completely dry after cleaning. When ethylene oxide gas is used as the gas
disinfectant, follow the operating instructions provided by the manufacturer of
the gas disinfectant.
NOTE
●
The disinfectant temperature must not exceed 70°C (158°F). Plastics in the pressure
transducer may deform or melt above this temperature.

CHAPTER 19:
CO2 MONITORING
INTRODUCTION
CO2 monitoring is to monitor the respiration of patient by detecting the concentration of CO 2
generated during respiration. The maximum concentration of CO2 at the end of exhalation is called
End-Tidal CO2 (EtCO2). The minimum concentration of CO2 at the end of inspiration is called
Fractional Inspiratory CO2 (FiCO2). CO2 is generated by cells in the body during metabolizing, and
is breathed out via breath system. The concentration of CO2 breathed out from lung reflects directly
the situation of metabolizing and breathe system. If the concentration of CO 2 is high, it means that
metabolizing is excited, such as blood poisoning or acute fever. If the concentration of CO2 is low, it
is commonly because the output ability of heart is weak, or the heart stop beating, or the lung soak
for the flux of blood is low or oxygen it carried is not enough. Monitoring CO2 is used to warn the
doctor of the abnormal of breathe and metabolizing for hocused patient.
The concentration of CO2 is represented as a pressure level, with mmHg, kPa or % as its unit.
Generally, the acceptable value is 38mmHg (5.1kPa or 5%) when air pressure is 760mmHg. The
concentration of CO2 varies very fast from 0% to 5% normally. To detect the concentration of CO2
accurately, the monitor has to be very sensitive.
MONITORING PROCEDURE
Follow the procedure specified below to monitor the CO2.
1. Plug the dehydration vase into its receptacle, then push its bottom carefully to its position,

MAINTENANCE AND CLEANING
In case of an exception in the sampling system of the CO2 module, check for
entanglement of the sampling line. If the sampling line is not entangled, remove
the dehydration vase. In this situation, if the dehydration vase is not blocked,
the sampling line must have been blocked, and you must replace it with a new
one. If the dehydration vase has been blocked, you should replace it with a new
dehydration vase.
WARNING
●
●
●
●
The sampling line is disposable, must not re-sterilize or reuse it.
Do not press or limit the sampling line.
The dehydration vase is used to collect water drops condensed in the sampling airway and
prevent water drops from entering the module. When the collected water reaches to a
certain amount, remove the water to avoid blocking the airway.
In the long-term use, dust or other substances may lower the air permeability of the filter
material in the dehydration vase and may block the airway. In this situation, the
dehydration vase must be replaced.
NOTE
●
The sampling line must be recycled or disposed of properly, complying with the local laws.

(cellular/cordless) telephones and land mobile radios, amateur radio, AM and
FM radio broadcast and TV broadcast cannot be predicted theoretically with
accuracy. To assess the electromagnetic environment due to fixed RF
transmitters, an electromagnetic site survey should be considered. If the
measured field strength in the location in which the equipment is used
exceeds the applicable RF compliance level above, the equipment should be
observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the
equipment.
b. Over the frequency ranges 150kHz to 80MHz, field strengths should be
less than 3V/m.

Recommended separation distances between portable and mobile RF communication and
the equipment
The equipment is intended for use in an electromagnetic environment in
which radiated RF disturbance are controlled. The customer or the user of
the equipment can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF
communication equipment (transmitters) and the equipment as
recommended below, according to the maximum output power of the
communication equipment.

For transmitters at a maximum output power not listed above, the
recommended separation distanced in meters (m) can be determined using
the equation applicable to the frequency of the transmitter, where P is the
maximum output power rating of the transmitter in watts (W) according to
the transmitter manufacturer.
NOTE: At 80 MHz and 800 MHz, the separation distance for the higher
frequency range applies.
NOTE: These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection from structures,
objects and people.
