Monitoring ECG
Overview
The electrocardiogram (ECG) measures electrical activity in the heart and displays it both
numerically and as a waveform. This chapter also describes arrhythmia and ST segment
monitoring.
ECG safety information
WARNING
Do not touch the patient, table, or the monitor during defibrillation.
WARNING
Use only compatible ECG cables for monitoring.
WARNING
When connecting the cables and electrodes, make sure no conductive part is in
contact with the ground. Verify that all ECG electrodes, including the neutral
electrode, are securely attached to the patient but not a conductive part or ground.
WARNING
Check every day whether there is skin irritation resulted from the ECG electrodes.
If yes, replace electrodes every 24 hours or change their sites.
WARNING
Place the electrode carefully and ensure a good contact.
WARNING
Check if the lead connection is correct before monitoring. If you unplug the ECG
cable from the socket, the screen will display the error message “ECG LEAD OFF”
and an audible alarm sounds.
WARNING
When using the monitor with the defibrillator or other high-frequency equipment,
use defibrillator-proof ECG leads to avoid burns.
WARNING
When using electrosurgery (ES) equipment, do not place an electrode near the
grounding plate of the electrosurgery device: otherwise, more interference will be
evident on the ECG waveform.
WARNING
For paced patients, you must set Pace to On. If it is incorrectly set to Off, the
monitor could mistake a pace pulse for a QRS and fail to alarm during asystole.
WARNING
The simultaneous use of cardiac pacemaker and other patient-connected
equipment may cause a safety hazard.
- 43 -
Instructions for Use Vista 120 Patient Monitor
CAUTION
If patients may be defibrillated, be sure to use defibrillation-proof ECG cables, otherwise,
the ECG cables will be damaged.
NOTE
• Interference from a non-grounded instrument near the patient and ESU interference
can cause inaccuracy of the waveform.
•
IEC/EN60601-1-2 (protection against radiation is 3 V/m) specifies that the electrical
field density exceeding 1V/m may cause measurement error in various frequencies. It
is accordingly suggested to not use equipment generating electrical radiation near
ECG/RESP monitoring devices.
•
In the default settings of the monitor, the ECG waveforms are the first two waveforms
from the top in the waveform area.
•
For measurements in or near the heart connect the monitor to the potential
equalization system.
•
For protecting the environment, the used electrodes must be recycled or disposed of
properly.
ECG display
The figure below is for reference only.
The symbol “①” indicates the lead name of the displayed waveform; refer to chapter “Selecting
calculation lead”.
The symbol “②” indicates waveform gain; refer to chapter “Changing the size of the ECG
waveform”.
The symbol “③” indicates Filter setting; refer to chapter “Changing the ECG filter setting”.
Changing the size of the ECG waveform
If any of the displayed ECG waveforms are too small or clipped, the size can be changed. Select
ECG Waveform Setup > ECG Gain, then select an appropriate factor from the pop-up box to
adjust the ECG waveform.
X0.125 to make strength of ECG signal waveform of 1 mV become 1.25 mm;
- 44 -
Instructions for Use Vista 120 Patient Monitor
X0.25 to make strength of ECG signal waveform of 1 mV become 2.5 mm;
X0.5 to make strength of ECG signal waveform of 1 mV become 5 mm;
X1 to make strength of ECG signal waveform of 1 mV become 10 mm;
X2 to make strength of ECG signal waveform of 1 mV become 20 mm;
Auto let the monitor choose the optimal adjustment factor for all the ECG waveforms.
Changing the ECG filter settings
The ECG filter setting defines how ECG waveforms are smoothed. An abbreviation indicating
the filter type is shown under the lead label on the monitor display. Filter settings do not affect
ST measurement.
To change the filter setting in the ECG Setup menu, select Filter and then select the appropriate
setting.
•
Monitor: Use this mode under normal measurement conditions.
•
Surgery: The filter reduces interference to the signal. It should be used if the signal is
distorted by high- or low-frequency interference. High frequency interference usually results
in large amplitude spikes making the ECG signal look irregular. Low-frequency interference
usually leads to a wandering or rough baseline. In the operating room, the Filter reduces
artifacts and interference from HF surgical equipment. Under normal measurement conditions,
selecting Surgery may distort the QRS complexes too much and thus interfere with the
clinical evaluation of the ECG displayed on the monitor.
•
Diagnos: Use when diagnostic quality is required. The unfiltered ECG waveform is displayed
so that changes such as R-wave notching or discrete elevation or depression of the ST
segments are visible.
Using ECG alarms
ECG alarms can be switched on and off. Changes to high and low alarm limits can be made using
the same methods used in other measurement alarms. Refer to chapter “Alarms” for more
information. Only ECG special alarm features are described in this chapter.
Selecting calculation lead
On the Normal dialog box, the user can select either 3 LEADS or 5 LEADS for this item.
Normal QRS complex is defined as:
•
The normal QRS should be either completely above or below the baseline and it should not be
biphasic. For paced patients, the QRS complexes should be at least twice the height of pace
pulses.
•
The QRS should be tall and narrow.
•
The P-waves and the T-waves should be less than 0.2 mV.

Monitoring procedure
Preparation
Skin is a poor conductor of electricity. Prepare the patient's skin to facilitate good electrode
conductivity.
•
Select sites with intact skin, without impairment of any kind.
•
Shave hair from sites, if necessary.
•
Wash sites thoroughly with soap and water. (Never use ether or pure alcohol, because this
increases skin impedance).
•
Rub the skin briskly to increase capillary blood flow in the tissues and remove skin scurf and
grease.
Connecting ECG cables
1.
Attach a clip or snap to the electrodes prior to placement.
2.
Place the electrodes on the patient. Before attaching, apply some conductive jelly on the
electrodes if the electrodes are not electrolyte self-supplied.
3.

V-Electrode Placement for 5-lead
Recommended ECG lead placement for surgical patients
WARNING
When using HF surgical equipment, leads should be placed in a position in equal
distance from the cautery knife and the electrosurgery grounding plate to avoid
burning the patient. HF surgical equipment wires and ECG cable must not be
tangled up.
ECG leads are used mainly for monitoring patient vital signs. When using the patient monitor
with other HF surgical equipment, use defibrillator-proof ECG leads.
The placement of the ECG leads depends on the type of surgery. For example, during open heart
surgery the electrodes can be placed laterally on the chest or back. In the operating room, artifacts
may affect the ECG waveform due to the use of ES (electrosurgery) equipment. To help reduce
this interference, the electrodes can be placed on the right and left shoulders, the right and left
sides near the abdomen and the chest lead on the left side at mid-chest. Avoid placing the
electrodes on the upper arms, which might result in a small waveform.
NOTE
• If an ECG waveform is not accurate (with electrodes are tightly attached), change the
lead.
•
Interference from a non-grounded instrument near the patient can cause inaccurate
waveforms.

ECG menu setup
Setting alarm source
To change the alarm source, select ECG Setup > Alarm Source. Select from the following
options:
HR: HR is HR/PR alarm source;
PR: PR is HR/PR alarm source;
AUTO: If the Alarm Source is set to Auto, the monitor will use the heart rate from the ECG
measurement as the alarm source whenever the ECG measurement is switched on. At least one
ECG lead can be measured. The monitor will automatically switch to Pulse for the alarm source
if:
•
a valid ECG lead can no longer be measured and
•
a Pulse source is switched on and available.
The monitor uses the pulse rate from the currently active measurement as system pulse. While
Pulse is the alarm source, all arrhythmia and ECG HR alarms are switched off. If an ECG lead
becomes available again, the monitor automatically uses HR as alarm source.
Smart lead off
In 5 LEADS mode, if CH1 and CH2 are disabled due to lead off for example, the system selects
other modes to collect an ECG waveform.
To change the smart lead off setting, select ECG Setup > Smart Leadoff. Select options from
the pop-up menu.
Setting beat volume
Beat volume is derived from HR or PR, depending on the HR alarm setting. To change the beat
volume, select ECG Setup > Beat Volume, and select the desired volume from the pop-up menu.
Six selections are available: 0, 1, 2, 3, 4, 5. 5 is maximum volume. 0 is mute.

NOTE
• When monitoring a patient with a pacemaker, set Pace to On. If monitoring a patient
without a pacemaker, set Pace to Off.
•
If Pace is set to On, the system will not perform some types of ARR analysis.
WARNING
Some pace pulses can be difficult to reject. When this happens, the pulses are
counted as a QRS complex, and could result in an incorrect HR and failure to
detect cardiac arrest or some arrhythmias. Keep pacemaker patients under close
observation.
ECG calibration
Selecting this item from the ECG Setup menu inserts a square wave into the ECG waveform that
can be used to estimate the amplitude accuracy of that waveform. Select the item again to turn off

About ST measurement points
The ST value for each beat complex is the vertical difference between the isoelectric (ISO) point
and the ST point, as shown in the diagram below. The ISO point provides the baseline, and the
ST point is at the midpoint of the ST segment. The J point is where the QRS complex changes its
slope. It is a fixed distance away from the ST point and can be useful during positioning.
DEF POINT
- 52 -
Instructions for Use Vista 120 Patient Monitor
The ST and ISO measurement points need to be adjusted when monitoring is started, and if the
patient's heart rate or ECG morphology changes significantly. Always ensure that ST
measurement points are appropriate for the patient. Abnormal QRS complexes are not considered
in ST segment analysis.
Adjusting ST and ISO measurement points
Depending on the monitor’s configuration, the ST point can be positioned as well.
These two points can be adjusted by turning the knob. When adjusting ST measurement point, the
system shows the ST measurement point window. The system displays the QRS complex
template in the window and can be adjusted using the highlight bar. The user can select ISO or
ST by switching the knob left or right to move the cursor line. When the cursor is at the desired
position, the base point or the measurement point can be selected.
Arrhythmia monitoring
Arrhythmia analysis
The arrhythmia algorithm is used to monitor clinical neonatal and adult ECG. It also detects heart
rate and ventricular rhythm changes, arrhythmia events, and generates alarm information. The
arrhythmia algorithm can monitor paced and non-paced patients. Qualified personnel can use
arrhythmia analysis to evaluate patient condition (such as heart rate, PVCs frequency, rhythm and
ectopic beat). The arrhythmia algorithm can also monitor patients and generate arrhythmia
specific alarms.
The monitor can support up to 16 different arrhythmia analyses.

Monitoring RESP
Overview
The monitor measures respiration from the amount of thoracic impedance between two ECG
electrodes. The change of impedance between the two electrodes, (due to the thoracic movement),
produces a respiratory waveform on the screen.
RESP safety information
WARNING
If you do not set the detection level for the respiration correctly in manual
detection mode, it may not be possible for the monitor to detect apnea. If you set
the detection level too low, the monitor is more likely to detect cardiac overlay, and
to falsely interpret cardiac overlay as respiratory activity in the case of apnea.
WARNING
The respiration measurement does not recognize obstructive and mixed apneas - it
only initiates an alarm when a pre-adjusted time has elapsed since the last
detected breath.
WARNING
If operating under conditions according to the EMC Standard EN 60601-1-2
(Radiated Immunity 3 V/m), field strengths above 1 V/m may cause erroneous
measurements at various frequencies. Therefore it is recommended to avoid the
use of electrically radiating equipment in close proximity to the respiration
measurement unit.
NOTE
The RESP monitoring is not recommended to be used on patients who are very active, as
this can cause false alarms.

Instructions for Use Vista 120 Patient Monitor
The Resp signal is always measured between two of the ECG electrodes. There are two standard
ECG leads for selection: I lead (RA and LA) and II lead (RA and LL).
Electrodes Placement for 5-lead
Cardiac overlay
Cardiac activity that affects the Resp waveform is called cardiac overlay. This occurs when Resp
electrodes detect impedance changes caused by rhythmic blood flow. Correct electrode placement
can reduce cardiac overlay.
Chest expansion
Some patients, especially neonates, expand their chests laterally. In this case, place the two
respiratory electrodes in the right midaxillary and left lateral chest areas at the maximum
expansion point. This placement optimizes respiratory waveform results.
Abdominal breathing
Some patients with restricted chest movement breathe mainly abdominally. In this case, place the
LL electrode on the left abdomen at the point of maximum abdominal expansion. This placement
optimizes respiratory waveform results.
NOTE
Place the red and green electrodes diagonally to optimize the respiration waveform. Do
not position electrodes over the liver or the heart’s ventricles. This is an especially
important safety procedure for neonates.
Selecting resp lead
To change Resp lead: From the Resp Setup menu, select Resp Lead, then choose the appropriate
lead from the pop-up list.

Monitoring SpO2
Overview
The SpO2 value is derived from the absorption of pulse blood oxygen by red and infrared light
using a finger sensor and a SpO2 measuring unit. SpO2 Plethysmogram measurement is employed
to determine the oxygen saturation of hemoglobin in the arterial blood. If, for example, 97 % of
the hemoglobin molecules in the red blood cells of the arterial blood combine with oxygen, then
the blood has a SpO2 oxygen saturation of 97 %. The SpO2 numeric on the monitor will read
97 %. The SpO2 numeric shows the percentage of hemoglobin molecules which have combined
with oxygen molecules to form oxyhemoglobin. The SpO2/PLETH parameter can also provide a
pulse rate signal and a plethysmogram waveform.
SpO2 safety information
WARNING
If the SpO2 sensor does not work properly, reconnect the sensor or use a new one.
WARNING
Do not use sterile supplied SpO2 sensors if the packaging or the sensor is
damaged.
WARNING
Prolonged and continuous monitoring may increase the risk of unexpected change
of dermal condition such as abnormal sensitivity, rubescence, vesicle, repressive
putrescence, and so on. It is especially important to check the sensor placement of
neonatal patients and patients with poor perfusion or immature dermogram by
light collimation and proper attaching strictly according to changes of the skin.
More frequent examinations may be required for different patients.
WARNING
Tissue damage may be caused by incorrect application or prolonged measurement
duration using the sensor (more than 4 hours). Inspect the sensor periodically
according to the sensor user manual.
WARNING
Neonate SpO2 sensor can only be used when required, no more than 20 min at a
time.
WARNING
Use only Dräger permitted sensors and extension cables with the oximeter. Other
sensors or extension cables may cause improper monitor performance and/or
minor personal injury.
NOTE
• Make sure the fingernail covers the light window. The wire should be placed on the
backside of the hand.
•
The amplitude of the SpO2 waveform is not proportional to the pulse volume.
- 59 -
Instructions for Use Vista 120 Patient Monitor
•
Avoid placing the sensor on extremities with an arterial catheter, or intravascular
venous infusion line.
•
Do not use a functional tester to access the SpO2 accuracy.
•
The function of SpO2 measurement does not require calibration.
•
The materials with which the patient or any other person can come into contact must
be conforming to standard ISO10993.
Measuring SpO2
1. Select the correct patient category setting (adult/pediatric and neonatal). This is used to
optimize the calculation of the SpO2 and pulse numerics.
2. During measurement, ensure that the application site:
-
has a pulsatile flow, ideally with a good circulation perfusion.
-
has not changed in its thickness, causing an improper fit of the sensor.
Measurement procedure
1. Switch on the monitor.
2. Attach the sensor to the appropriate site of the patient finger.
3. Plug the sensor extension cable connector into the SpO2 socket on the SpO2 module.
Mounting of the Sensor
WARNING
Inspect the application site every two to three hours to ensure skin quality and
correct optical alignment. If the skin quality changes, move the sensor to another
site. Change the application site at least every four hours.
NOTE
Injected dyes such as methylene blue or intravascular dyshemoglobins such as
methemoglobin and carboxyhemoglobin may lead to inaccurate measurements.

Instructions for Use Vista 120 Patient Monitor
Interference can be caused by:
•
High levels of ambient light or strobe lights or flashing lights (such as fire alarm lamps).
(Hint: cover application site with opaque material.)
•
Electromagnetic interference.
•
Excessive patient movement and vibration.
Understanding SpO2 alarms
This chapter describes SpO2 specific alarms. See the chapter “Alarms” for general alarm
information. SpO2 alarms are adjustable and have high and low limits.
Adjusting alarm limits
In SpO2 Setup menu:
•
Select the SpO2 High Alarm Limit and chose the desired high alarm limit.
•
Select the SpO2 Low Alarm Limit and chose the desired low alarm limit.
WARNING
High oxygen levels may predispose a premature infant to retrolental fibroplasia. If
this is a consideration do not set the high alarm limit to 100 %, which is equivalent
to switching the alarm off.
Setting SpO2 as pulse source
1. In the PR Setup menu, select PR Source;
2. Select SpO2 from the pop-up list.
Setting pitch tone
If tone modulation is on, the PR sound lowers when the SpO2 level drops. In SpO2 Setup menu,
select pitch tone to toggle between On and Off.
Setting sensitivity
Sensitivity allows the user to set the refresh frequency. High is the highest SpO2 refresh
frequency value. To change the sensitivity:
1. Select the SpO2 Setup menu;

Instructions for Use Vista 120 Patient Monitor
Monitoring PR
Overview
The pulse numeric counts the arterial pulsations that result from heart mechanical activity in beats
per minute (bpm) from the measured SpO2 signal.
Setting PR volume
Six selections are available: 0, 1, 2, 3, 4, and 5. 5 is the maximum volume. 0 is mute. PR Volume
can be changed in the PR Setup menu.
Using pulse alarms
The user can change pulse rate alarm limits in the PR Setup menu by selecting PR Alarm Limit.
Pulse alarms are only generated when the active alarm source is set to Pulse. The pulse source is
set as system pulse and pulse alarms are switched on.
Selecting the active alarm source
In most cases, the HR and Pulse numerics are identical. To avoid simultaneous alarms on HR and
Pulse, the monitor uses either ECG or Pulse as its active alarm source. To change the alarm
source, select Alarm Source in the ECG/Pulse Alarms menu, then select
•
HR: If HR should be the alarm source for HR/Pulse.
•
PR: If Pulse is selected as the active alarm source, the monitor will prompt the user to
confirm his choice. If Pulse is selected as the alarm source, all arrhythmia and ECG HR
alarms are switched off.
•
AUTO: If the Alarm Source is set to Auto, the monitor will use the heart rate from the ECG
measurement as the alarm source whenever the ECG measurement is switched on and at least
one ECG lead can be measured without a technical alarm condition. The monitor will
automatically switch to Pulse as the alarm source.

Instructions for Use Vista 120 Patient Monitor
Monitoring NIBP
Overview
This monitor uses the oscillometric method for measuring NIBP. It can be used for adult,
pediatric and neonatal patients.
Oscillometric devices measure the amplitude of pressure changes in the occluding cuff as the cuff
deflates from above systolic pressure. The amplitude suddenly increases as the pulse breaks
through the occlusion in the artery. As the cuff pressure decreases further, the pulsations increase
in amplitude, reach a maximum (which approximates to the mean pressure), and then diminish.
In adult and pediatric mode, the blood pressure measurements determined with this device comply
with the American National Standard for Electronic or Automated Sphygmomanometers
(ANSI/AAMI SP10-1992) in relation to mean error and standard deviation, when compared to
auscultatory measurements in a representative patient population. For the auscultatory reference,
the fifth Korotkoff sound was used to determine the diastolic pressure.
In neonatal mode, the blood pressure measurements determined with this device comply with the
American National Standard for Electronic or Automated Sphygmomanometers (ANSI/AAMI
SP10-1992) in relation to mean error and standard deviation, when compared to intra-arterial
measurements in a representative patient population.
NIBP safety information
The monitor and peripheral devices are protected against high-frequency interference from
defibrillators and electrosurgical units and against 50- and 60-Hz power line interference.
WARNING
Do not measure NIBP on patients with sickle-cell disease or any condition where
skin damage has occurred or is expected.
WARNING
Use clinical judgment to decide whether to perform frequent unattended blood
pressure measurements on patients with severe blood clotting disorders because
of the risk of hematoma in the limb fitted with the cuff.
WARNING
Before starting a measurement, verify that you have selected a setting appropriate
for your patient (adult, child, or neonate). An incorrect setting may be dangerous
for children, because of higher measurement pressures.
WARNING
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.
- 63 -
Instructions for Use Vista 120 Patient Monitor
WARNING
Make sure that the air tubing connecting the blood pressure cuff and the monitor is
neither blocked nor tangled.
NOTE
• Do not start NIBP measurements during low battery conditions (the monitor may turn
off automatically).
•
If an alarm occurs or measurement fails, discontinue the measurement.
•
If you spill liquid onto the equipment or accessories, particularly if there is a chance
that it can get inside the tubing or the measurement device, contact your service
personnel.
•
Continuous use of the automatic measuring mode for short intervals may lead to the
discomfort of the patient.
Measurement limitations
Measurements are impossible with heart rate extremes of less than 40 bpm or greater than 240
bpm, or if the patient is on a heart-lung machine.
The measurement may be inaccurate or impossible in the following situations:
•
A regular arterial pressure pulse is hard to detect.
•
Patients with cardiac arrhythmias.
•
Patients with excessive and continuous movement such as shivering or convulsions.
•
Patients with rapid blood pressure changes.
•
Patients with severe shock or hypothermia that reduces blood flow to the periphery.
•
Obese patients, where a thick layer of fat surrounding a limb dampens the oscillations coming
from the artery.
•
Patients with an edematous extremity.
Measurement methods
There are three methods of measuring NIBP:
•
Manual - measurement on demand.
•
Auto - continually repeated measurements (between 1 and 480 minute adjustable interval).
•
Continual - NIBP measurements run consecutively in five minutes, and then the monitor
switches to manual mode.

Monitoring TEMP
Overview
Body temperature is measured using a thermistor probe (a semiconductor whose resistance
changes with temperature) placed appropriately on the patient.
Two TEMP probes can be used simultaneously to measure two TEMP values. The monitor
automatically calculates the temperature difference. The default configuration is axilla sensor for
adult.
TEMP safety information
WARNING
Verify probe cables fault detection before using the probe to monitor the patient. If
you unplug the temperature probe cable of channel 1 from the socket, the screen
will display the error message TEMP1 SENSOR OFF and the audible alarm is
activated. It is the same for the other channel.
WARNING
Handle the TEMP probe and cable carefully. When they are not in use, you should
coil the probe and cable into a loose circle. Pulling the wire inside the cable may
mechanically damage the probe and the cable.
NOTE
Disposable TEMP probe can only be used once per patient.
TEMP monitoring setup
•
If disposable TEMP probes are used, connect the TEMP cable to the monitor and then
connect the probe to the cable. With a reusable TEMP probe the probe can be connected
directly to the monitor.
•
Apply the TEMP probes securely to the patient.
•
Switch on the monitor
It takes 2 to 3 min for the body temperature to stabilize.
Calculating temp difference
The monitor can calculate and display the difference between two temperature values by
subtracting the second value from the first. The difference is labeled TD.

Monitoring IBP (optional)
Overview
IBP is measured by means of a catheter inserted into the circulatory system. A pressure
transducer connected to the catheter converts the mechanical force exerted by the blood into an
electrical signal. This is displayed graphically as pressure versus time and as numerics on the
monitor screen.
The monitor measures direct blood pressure of one selected blood vessel through two channels
and displays waveforms and numerics for the measured direct blood pressure (SYS, DIA and
MAP).
For further information on the IBP Kit, refer to the accompanying Instructions for Use of the
manufacturer.
IBP safety information
WARNING
The operator should avoid contact with the conductive parts of the device when it
is connected to the patient.
WARNING
When the monitor is used with HF surgical equipment, avoid conductive
connections of the transducer and the cables to the HF surgical equipment. This is
to protect against burns to the patient.
WARNING
Disposable IBP transducer or domes should not be reused.
WARNING
If any kind of liquid, other than solution to be infused in pressure line or transducer,
is splashed on the equipment or its accessories, or enters the transducer or the
monitor, contact your service personnel immediately.
NOTE
• Use only the pressure transducer listed in the IBP accessories
Monitoring procedures
Preparatory steps for IBP measurement:
1. Connect the pressure cable to the corresponding socket and switch on the monitor.
2. Flush the system with a normal saline solution. Ensure that the system is free of air bubbles.
3. Connect the patient’s catheter to the pressure line. Ensure there is no air present in the
catheter or pressure line.
4. Position the transducer so that it is at the same level as the patient’s heart, approximately
mid-axillary line.

Instructions for Use Vista 120 Patient Monitor
5. For the label name selection, refer to chapter “Selecting a Pressure for Monitoring”.
6. To zero the transducer, refer to chapter “Zeroing the Pressure Transducer”.
WARNING
If there are air bubbles in the pressure line or the transducer, flush the system with
the infused solution.
Selecting a pressure for monitoring
The user can assign a pressure label to uniquely identify each pressure. The monitor then uses
that label’s stored settings (i.e., for color, scale and alarm settings) and selects which algorithm is
used to process the pressure signal. An incorrect label can lead to incorrect pressure values. To
select the label, refer to the following table:
Label

ART
Arterial blood pressure
PA
Pulmonary artery pressure
CVP
Central venous pressure
ICP
Intracranial pressure
LAP
Left atrial pressure
RAP
Right atrial pressure
P1-P2
Alternative non-specific pressure labels
Zeroing the pressure transducer
To avoid inaccurate pressure readings, the monitor requires a valid zero. Zero the transducer in
accordance with your hospital’s policy (at least once per day).
Zeroing must be performed:
•
When a new transducer or tubing is used;
•
Every time the transducer cable is reconnected to the monitor;
•
If the monitor’s pressure readings seem to be incorrect.
When using a pressure module, the zero information is stored in the module.
To zero a pressure measurement:
1. Turn off the stopcock to the patient.
2. Vent the transducer to atmospheric pressure. This compensates for the static and atmospheric
pressure exerted on the transducer.
3. In the setup menu for pressure, select Zero <Press>.
4. When the message <Press> zero done is displayed, close the stopcock to atmospheric
pressure and open the stopcock to the patient.

Monitoring CO2 (optional)
Overview
The monitor uses a Capnostat 5 CO2 module (c5) as the means for MainStream method CO2
monitoring. MainStream measurement uses a CO2 sensor attached to an airway adapter that is
directly inserted into the patient’s breathing system.
The principle of CO2 measurement is primarily based on the fact that CO2 molecules absorb
4.3μm infrared rays. Absorption intensity is proportional to the CO2 concentration of the patient
sample.
CO2 safety information
WARNING
Do not use the device in the environment with flammable anesthetic gas.
WARNING
The device should be used by trained and qualified medical personnel.
WARNING
Nitrous oxide, elevated levels of oxygen, helium, xenon, halogenated
hydrocarbons, and barometric pressure can influence the CO2 measurement.
WARNING
The monitor will be damaged if any tube from the CO2 module is disconnected, or
the air tube/the air inlet/the air outlet are plugged by water or other materials.
WARNING
The accuracy of the CO2 measurement will be affected by the following reasons:
the airway was highly obstructed; a leaky airway connection or quick variation of
environment temperature.
WARNING
Follow precautions for electrostatic discharge (ESD) and electromagnetic
interference (EMI) to and from other equipment.
WARNING
In the presence of electromagnetic devices (e.g., electrocautery), patient
monitoring may be interrupted due to electromagnetic interference.
Electromagnetic fields up to 20V/m will not adversely affect module performance.
WARNING
Do not place the sensor cables or tubing in a way that may cause tangling or
strangulation.
WARNING
Do not store the CO2 Module at temperatures less than -40 ºC or greater than
+70 ºC. Do not operate the CO2 Module at temperatures less than 0 ºC or greater
than 40 ºC.

EMC Declaration
General information
The EMC compliance of the medical device is also applicable to the external cables, transducers,
and accessories specified in the list of accessories. In addition, accessories which do not affect
EMC compliance may be used if no other reasons forbid their use (see other sections of the
Instructions for Use). The use of non-compliant accessories may result in increased emissions or
decreased immunity of the medical device.
The medical device may only be used adjacent to or stacked with other devices when the
configuration is approved by Dräger. If adjacent or stacked use of non-approved configurations is
inevitable, the medical device must be observed to verify normal operation in the said
configuration. In any case, strictly observe the Instructions for Use of the other devices.
Electromagnetic emissions
When selecting wireless systems (wireless communication devices, pager systems, etc.) for use in
installations where wireless networking is used, ensure that operating frequencies are compatible.
Low-level signals such as ECG are particularly susceptible to interference from electromagnetic
energy. While the equipment meets the testing described below, it will not ensure perfect
operation. The ‘quieter’ the electrical environment the better. In general, increasing the distance
between electrical devices decreases the likelihood of interference.

The medical device is intended for use in an electromagnetic environment as specified below.
The user must ensure its use in such an environment.

Electromagnetic environment
The medical device uses RF energy
only for its internal function.
Therefore, its RF emissions are very
low and are not likely to cause any
interference in nearby electronic
equipment.
The medical device is suitable for
use in all establishments other than
domestic establishments and those
directly connected to the public
low-voltage power supply network
that supplies buildings used for
domestic purposes.

Field strengths from fixed transmitters, such as base stations for radio (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 Vista 120 is used
exceeds the applicable RF compliance level above, Vista 120 should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating Vista 120.
