from its internal battery.
WARNING: To prevent electrical hazards to all personnel, this monitor must be properly grounded. Connect the
monitor only to a three-wire, grounded, hospital grade receptacle. The three-conductor plug must be inserted into a
properly wired three-wire receptacle; if a three-wire receptacle is not available, a qualified electrician must install
one in accordance with the governing electric code.
WARNING: Do not under any circumstances remove grounding conductor from the power plug.
WARNING: The power cable supplied with this equipment provides for this protection. Do not attempt to defeat
this protection by modifying the cable or by using ungrounded adapters or extension cables. The power cord and
plug must be intact and undamaged. To disconnect the equipment from the mains power unplug the power cord.
WARNING: Do not connect to an electrical outlet controlled by a wall switch or dimmer.
WARNING: If there any doubt about the integrity of the protective earth conductor arrangement, operate the
monitor on internal battery power until the AC power source protective conductor is fully functional.
WARNING: Do not place the monitor in any position that may cause it to fall on the patient. Do not lift the monitor
by the power supply cord or patient cable, use only the handle on the monitor.
WARNING: Electric shock hazard! Do not remove covers or panels. Refer service to qualified service
personnel.
WARNING: To avoid electrical shock, disconnect the monitor from its power source before changing fuses.
Replace fuses only with same type and rating (1.6ASB, Metric 5x20mm, 250V).
WARNING: Do not clean monitor while it is on and/or plugged into a power source.
WARNING: If unit is accidentally wet, discontinue use until dry and then test unit for proper operation before reuse
on patient.
WARNING: This unit uses a common isolation path for the ECG leads. Do not connect any non-isolated
accessories to the ECG input when connected to a patient, as this may compromise the safety of the unit. When
attached to other devices, insure that the total chassis leakage currents of all units do not exceed 300 μA.
Explosion
DANGER: Explosion hazard! Do not use this equipment in the presence of flammable anesthetics or other
flammable substance in combination with air, oxygen-enriched environment or nitrous oxide.

Vital-Guard 450C Operation and Maintenance Manual
SAFETY
Patient Connections
Patient connections are electrically isolated. For all connections use isolated probes. Don’t let patient connections
contact other conductive parts, including earth. See instructions for patient connections in this manual.
Carefully route patient cables to reduce the possibility of patient entanglement or strangulation.
Leakage current is limited internally by this monitor to less than 10 μA. However, always consider cumulative
leakage current that can be caused by other equipment used on the patient at the same time as this monitor.
To ensure that the leakage current protection remains within the specifications, use only the patient cables specified
in this manual. This monitor is supplied with protected lead wires. Do not use cables and leads with unprotected
lead wires having exposed conductors at the cable end. Unprotected lead wires and cables may pose an
unreasonable risk of adverse health consequences or death.
If an alarm condition occurs while the alarms are set to off, the only alarm indication will be visual displays and
symbols related to the alarm condition.
MRI
The model 450C should not be used within the magnetic field during Magnetic Resonance Imaging.
Pacemakers
Rate meters might continue to count the pacemaker rate during occurrences of cardiac arrest or some arrhythmias.
Do not rely on rate meter alarms. Keep pacemaker patients under close surveillance.
Electrosurgery
To avoid the potential of electrosurgery burns at monitoring sites, ensure proper connection of the electrosurgery
return circuit as described by manufacturer’s instructions. If improperly connected, some electrosurgery units might
allow energy to return through the ECG electrodes, SpO2 sensors, Pressure Transducers, EtCO2 sensors, and
Temperature probes. To further reduce the potential of burns, locate the SpO2 sensors, Pressure Transducers, EtCO2
sensors, and Temperature probes as described in the manufacturer’s instructions.
Defibrillation Protection
This equipment is protected against 360 J discharge and electrosurgery potentials. The monitor is internally
protected to limit current through the electrodes to prevent injury to the patient and damage to the equipment as long
as the defibrillator is used in conformance with the manufacturer’s instructions.
EMC
This equipment has been certified to be protected to emissions and immunity according to IEC-60601-1-2.

For continued Defibrillation protection and proper Respiration monitoring use only patient cables with 1kΩ series
resistors. It is important to use only patient cables with 1kΩ series resistors because the respiration circuit is tuned to
operate with series resistors.
For 3-lead configuration monitors, use 3-lead patient cable with 1kΩ series resistors. Ivy reorder no. 590197.
For 5-lead configuration monitors, use 5-lead patient cable with 1kΩ series resistors. Ivy reorder no. 590207.

Non-Invasive Blood Pressure (NIBP)
Pulse Oximetry
The Model 450C is available in several configurations, therefore, not all parameters are included in all monitors.
The use of the Model 450C is restricted to one patient at a time. The monitor is intended for use in emergency room,
recovery room, intensive care, and surgical applications and transport with 2.5 hours battery operation.
The Model 450C is suitable for use in presence of electrosurgery.
The Model 450C is not intended for use with any other physiological monitoring unit.
An optional integral recorder is available. Recorder settings are made through the monitor menus. Battery operation
consists of two rechargeable lead acid cells.
The display has four traces available and alphanumeric displays for data, alarms, and user information, such as
menus. The monitor automatically senses which devices are connected and acquires and displays data for the
parameters being used. Data for parameters not being used is not displayed. Areas for display of those parameters
are left blank.

Generates a 1 mV pulse at 70 bpm, respiration signal at 70 br/min, (coincidence check),
invasive blood pressures at 150/50, and temperatures at 40°C displayed on the screen and sent
to the rear panel. This key is used to verify that the monitor is functioning correctly. In TEST,
heart rate is always computed from the generated ECG.
Turns the alarm audio on and off. When off, the ALARMS OFF tag is displayed on the
screen.
Disables the audible and visual alarms for a two-minute period to allow the operator to
perform procedures that would otherwise set off the alarms. This avoids the problem of
turning off the alarms and forgetting to turn them back on. A message on the screen indicates
when this function is active. Press the ALARM PAUSE key again to return the alarms to
normal before the two minutes have expired.
Respiration Size
RESP SIZE
The up and down arrows control the relative size of the respiration signal. Size ranges are from
0 to 100%. This controls both the display size and the trigger sensitivity.
NOTE: If the respiration size is set for a very sensitive range, cardiac artifact can generate false triggers, causing a
coincidence alarm.
On
When the monitor is either plugged into an AC power source or operating on batteries,
the switch toggles from Stand By (off position) to ON providing power to the monitor’s
electronic circuits. The monitor must be connected to an AC source to be able to charge
the internal batteries.
NOTE: To disconnect the monitor from the mains power unplug the power cord.

BATTERY OPERATION
BATTERY OPERATION
Internal Battery
The model 450C is equipped with two internal batteries. This allows the monitor to operate for 2½ hours under its
own power.
In the event of a mains power failure, the model 450C will automatically switch to battery operation.
A BAT indicator in the lower right corner of the display graphically displays the approximate remaining charge of
the battery: full, 75 %, 50 %, 25 %.
When the remaining battery charge is less than 20 minutes, the BAT indicator flashes the word LOW and an audio
tone sounds every 15 seconds.
The battery is continuously charged whenever the ac power is connected, even when the monitor is turned off.
Charging time when the battery is fully discharged is 12 hours.
If monitor is not in regular service, i.e. weekly use, to ensure maximum battery life, it is recommended that, at least
once a month, the unit be run on battery until it turns itself off and then recharged.
Remove the batteries if the monitor will not be in regular use for more than six months.
Status of the Battery
The model 450 has three LED’s (label as Charged, Charging and Battery Fault) to indicate the status of the battery.
They are located in the bottom left corner of the faceplate. The following table shows the status of the battery
depending on the action (ON, OFF or FLASHING) of the LED’s.

ECG MONITORING
When ECG monitoring, the display shows the ECG waveform, the heart rate, heart rate limits (if DISPLAY
LIMITS is selected), lead selection, adult/neonate mode, and alarm indications. Also, a heart symbol, pulse, or BP
symbol flashes each time a heartbeat is detected, depending on whether the rate is being triggered by the ECG,
pleth, or blood pressure waveform.
Safety Considerations
Disposable products are intended for single-use only. Do not attempt to re-use these products.
. For ECG connections use insulated probes. Don’t
ECG Patient connections are electrically isolated Type CF
let patient connections contact other conductive parts, including earth. See instructions for patient connections in
this manual.
This monitor is supplied with protected lead wires. Do not use cables and leads with unprotected lead wires having
exposed conductors at the cable end. Unprotected lead wires and cables may pose an unreasonable risk of adverse
health consequences or death.
Leakage current is limited internally by this monitor to less than 10 μA. However, always consider cumulative
leakage current that can be caused by other equipment used on the patient at the same time as this monitor.
To avoid the potential of electrosurgery burns at ECG monitoring sites, ensure proper connection of the
electrosurgery return circuit as described by manufacturer’s instructions. If improperly connected, some
electrosurgery units might allow energy to return through the electrodes.

NOTE: We recommend that you always use five-lead cables with monitors having the five-lead option. The use of
many three-lead cables can cause poor quality signals and can inhibit the LEAD OFF alarm. When monitoring three
leads, use the five-lead cable and remove the two unnecessary patient leads.
Use only high quality silver/silver-chloride electrodes or equivalent.
Use the following procedure for ECG monitoring:
1.
Prepare each electrode site and apply the electrodes.
2.
Connect the patient cable to the monitor’s right side panel ECG input.
3.
Attach the leads to the electrodes.
Model 450C monitors with five-lead option can accommodate both three- and five-lead configurations.
4.
Use the procedures described in the following sections for alarm limit settings, lead selection, amplitude
adjustment, and enabling or disabling the filter. See the menu diagram below.
NOTE: For monitors designed to use both three- and five-lead cables, the LEAD OFF alarm tests only those leads
that are relevant to the selected lead setting.

ETCO2 MONITORING
END TIDAL CO2 MONITORING
General Description
The Ivy Model 450C monitor uses NonDispersive InfraRed (NDIR) gas measurement to determine CO2 gas
concentration. The NDIR measurement method uses fixed (non-scanning) frequencies of infrared (IR) light. NDIR
measurement is based on the phenomenon that higher gas concentrations in a given volume of gas in the path of an
IR light signal create more absorption of the IR light. Therefore, higher concentrations of an IR absorbing gas create
a measurably lower transmission of the IR light.
Components
The following components make up an NDIR instrument. See the illustration below.
IR Source: A source of infrared light.
The infrared light source actually produces a wide range of light at frequencies covering the IR band and extending
in either direction into the visible and ultraviolet spectra.
Sample Cell: The gas to be measured is transported into a sample cell with windows that allow the IR light to pass
through the gas sample. The Sensor Head is mounted on the sample cell, called the Airway Adapter. The Airway
Adapter has a constant volume and path length as seen by the Sensor Head. The Sensor Head and Airway Adapter
windows are chosen for their non-IR absorbing quality.
IR Filter: An optical bandpass filter is used to select a specific band of IR light centered on an exact wavelength.
The optical IR filter’s center wavelength is chosen for the specific gas to be measured (CO2). The monitor also needs
a reference channel which requires a second IR filter.
IR Detector: A lead selenide IR detector converts the IR light transmitted through the sample cell into an output
voltage.
48
Vital-Guard 450C Operation and Maintenance Manual
ETCO2 MONITORING
Sensor Head Components
The diagram below represents the components of the Sensor Head.
Sensor Head Case – The Sensor Head Case is sealed to control internal ambient CO2 concentration and to provide
sufficient moisture resistance for cleaning.
Hybrid Processing Board – The Hybrid Processing Board includes programmed control of:
Lamp Power on/off
Window Heating and Temperature Monitoring
Detector Block Heating and Temperature Monitoring
Multiplexing of Analog Signals
Non-Volatile Memory containing all unit-specific data
Bi-directional Digital Communications with the Signal Processing Board
Vital-Guard 450C Operation and Maintenance Manual
49
ETCO2 MONITORING
Lamp and Reflector Assembly – The lamp is pulsed on and off. Its collimated light beam travels through one Sensor
Head Window, through the Airway Adapter containing the patient sample, through the second Sensor Head Window,
and through the beam splitter.
Heated Windows – The Sensor Head Windows are heated to reduce condensation. A thermistor monitors window
temperature.
Beam Splitter – The Beam Splitter directs part of the light falling on it to the CO2 IR Detector and the balance of the
light to the Reference Channel Detector.
IR Filters – An optical band pass filter is located in front of both IR Detectors. Each filter passes to its detector only
the wavelength of light that is appropriate.
IR Detectors – The IR Detectors convert the light falling on them into analog signals. The CO2 IR Detector’s output
is relative to the CO2 concentration in the Airway Adapter, while the reference channel IR Detector is insensitive to
CO2 concentration.
Detector Preamplifier Board – The outputs of the IR Detectors are amplified and filtered. These analog signals are
fed through the Hybrid Processing Board’s multiplexer to the Signal Processing Board.
Heated Detector Block – The Detector Block is heated to stabilize the IR filter temperature. A thermistor monitors
Detector Block temperature.

Vital-Guard 450C Operation and Maintenance Manual
ETCO2 MONITORING
To demonstrate the absorption of specific IR wavelengths by CO2 gas, the chart below shows the amount of IR
transmission for various wavelengths of IR light through CO2. The CO2 filter passes infrared light in the range
between 4.22 and 4.32 microns.
The chart below shows that as the CO2 concentration increases from 2% to 10%, infrared light transmission
decreases. IR light transmission is inversely proportional to the IR light absorption of the gas. By measuring how
much light gets through the sample gas and the CO2 optical filter, we can calculate how much CO2 is present in the
gas sample.
Vital-Guard 450C Operation and Maintenance Manual

ETCO2 MONITORING
Complications of NonDispersive InfraRed (NDIR) Monitoring
IR Light Amplitude Changes – Changes in the output of the IR light source directly affect the IR detector’s voltage
output for a given gas sample.
In this monitor, the IR lamp pulses on and off. The on phase is created by a constant voltage, providing a consistent
light output. A consistent IR lamp output is more important than a specific output level.
Short and long term IR lamp amplitude changes are compensated for by use of a reference channel. A reference
channel output change can be assumed to be non-gas related, and common to the CO2 channel. Software data
processing compensates for IR lamp output changes. This same mechanism compensates for any other common
mode source of signal degradation, such as light beam obscuration by patient secretions.
Sample Gas Pressure Changes – Because a change in gas pressure in the Airway Adapter reduces the number of
CO2 molecules in the IR path, without airway adapter pressure compensation, changes in gas pressure would appear
as changes in CO2 concentration.
Typically, the monitor measures CO2 only during the patient’s expired breath phase. At this time, airway adapter
pressure is very close to local barometric pressure. The sensors are factory characterized and calibrated at sea level
where local barometric pressure, and airway adapter pressure is 760 Torr. The system also has the ability to set the
local barometric pressure into the monitor. The Sensor Head stores this pressure value and uses it to correct for the
difference in airway adapter pressure between calibration time and normal use.
Temperature Changes – Changes in the temperature of the IR filters, IR detectors, or sample gas (patient breath or
calibration gas) directly affect the IR detector’s voltage output for a given gas sample. Each of these must be either
held at a constant temperature or monitored for temperature compensation.
During the expired phase, the patient’s breath is slightly lower than body temperature (about 34°C). This relatively
constant temperature relieves the monitor of the need to control sample gas temperature or correct for its changes.
Changes in sample gas flow rate can cause small sample gas temperature changes. The sensors are factory
characterized and calibrated at 4.0 liters per minute.
NOTE: When using bottled calibration gas for span calibration or troubleshooting, its temperature might not be
34°C. The difference between calibration gas temperature and 34°C can cause CO2 measurement errors.
The IR filters and detectors are mounted on the Sensor Head’s detector block. Attached to the detector block is a
thermoelectric heater strip and a thermistor. The heater temperature holds the Detector Block, IR Filters, and IR
Detectors at a constant temperature (approximately 43°C).
Multiple IR Absorbing Gases – N2O, water vapor, and anesthetic agents also absorb IR light and might be present in
some applications. Each of these gases has different IR absorption characteristics, and choosing the correct CO2 and
reference channel IR filters reduces the “cross gas interference” effect.
Non-IR Absorbing Gases Present – The sample gas might also contain O2, N2O, or N2. Although O2 and N2 don’t
absorb IR, they can create NDIR measurement problems via “collision line broadening.”
The monitor uses assumed values for O2 and N2O and uses these values to compensate for “collision line
broadening.” The default values are 21.0% O2 and 0.0% N2O. Different values can be entered and stored in the
Sensor Head.
NOTE: When using a calibration gas for span calibration or troubleshooting, O2 and N2O concentrations must also
be entered.
52
Vital-Guard 450C Operation and Maintenance Manual
ETCO2 MONITORING
Zero Baseline and Span Calibration – The voltage output of the IR Detector has no absolute meaning until it is
established what CO2 detector voltage represents 0.00% CO2 gas concentration and what other voltage represents full
scale CO2 gas concentration (10.00%).
The voltage level when the IR Lamp is off, known as the “dark level,” is the minimum voltage output of the IR
Detector, and is used as the common reference for measuring all other IR Detector output voltages. When there is
0% CO2 in the sample gas, there is minimum IR absorption, and therefore, maximum IR transmission. This
measurement is the maximum output voltage of the IR Detector, and is stored in the system at each Zero Calibration.
All CO2 measurements are between these two values. The factory characterization of each unit includes the
calculation of the system’s CO2 response curve. A field Span Calibration calculates simple multipliers that allow
correction of long term component performance changes.
Nonlinearity – As the IR Detector output voltage decreases with increasing CO2 gas concentration, some
nonlinearities of NDIR technology must be managed.
The nonlinearity of the system’s response curves was determined during its development. This nonlinearity is
described in the resident CO2 response curve, and is automatically compensated for during data processing.

MASIMO SET® PULSE OXIMETRY MONITORING
MASIMO SET® PULSE OXIMETRY MONITORING
Overview
Pulse oximetry allows you to continuously and no invasively monitor a patient’s hemoglobin oxygen saturation. The
oximetry sensor contains two light emitting diodes (LEDs) that transmit specific wavelengths of light, which are
received by a photodetector.
Oxygen saturated blood absorbs light differently as compared to unsaturated blood. Thus the amount of light
absorbed by blood can be used to calculate the ratio of oxygenated hemoglobin to total hemoglobin in arterial blood.
The monitor displays this ratio as percent SpO2. Normal values typically range from 95 to 100% at sea level.
Principles of Operation
The Model 450C Pulse Oximeter is based on three principles:
1.
Oxyhemoglobin and deoxyhemoglobin differ in their absorption of red and infrared light (spectrophotometry).
2.
The volume of arterial blood in tissue and the light absorbed by the blood changes during the pulse
(plethysmography).
3. Arterio-venous shunting is highly variable and that fluctuating absorbance by venous blood is a major
component of noise during the pulse.
The Model 450C Pulse Oximeter as well as traditional pulse oximetry determines SpO2 by passing red and infrared
light into a capillary bed and measuring changes in light absorption during the pulsatile cycle. Red and infrared lightemitting diodes (LEDs) in oximetry sensors serve as the light sources, a photodiode serves as the photodetector.
Traditional pulse oximetry assumes that all pulsations in the light absorbance signal are caused by oscillations in the
arterial blood volume. This assumes that the blood flow in the region of the sensor passes entirely through the
capillary bed rather than through any arterio-venous shunts. The traditional pulse oximeter calculates the ratio of
pulsatile absorbance (AC) to the mean absorbance (DC) at each of two wavelengths, 660 nm and 940 nm.
S(660) = AC(660)/DC(660)
S(940) = AC(940)/DC(940)
The oximeter then calculates the ratio of these two arterial pulse-added absorbance signals:
R = S(660)/S(940)
The value of R is used to find the saturation SpO2 in a look-up table built into the oximeter’s software. The values in
the look-up table are based upon human blood studies against a laboratory co-oximeter on healthy adult volunteers in
induced hypoxia studies.

63
MASIMO SET® PULSE OXIMETRY MONITORING
The Model 450C Pulse Oximeter assumes that arterio-venous shunting is highly variable and that fluctuating
absorbance by venous blood is the major component of noise during the pulse. The Model 450C monitor
decomposes S(660) and S(940) into an arterial signal plus a noise component and calculates the ratio of the arterial
signals without the noise:
S(660) = S1 + N1
S(940) = S2 + N2
R = S1/S2
Again, R is the ratio of two arterial pulse-added absorbance signals and its value is used to find the saturation SpO2
in an empirically derived equation into the oximeter’s software. The values in the empirically derived equation are
based upon human blood studies against a laboratory co-oximeter on healthy adult volunteers in induced hypoxia
studies.
The above equations are combined and a noise reference (N’) is determined:
N' = S(660) - S(940) x R
If there is no noise N' =0; then S(660) = S(940) x R which is the same relationship for the traditional pulse oximeter.
The equation for the noise reference is based on the value of R, the value being seeked to determine the SpO2. The
Model 450C software sweeps through possible values of R that correspond to SpO2 values between 1% and 100%
and generates an N' value for each of these R values. The S(660) and S(940) signals are processed with each possible
N' noise reference through an adaptive correlation canceller (ACC) which yields an output power for each possible
value of R (i.e., each possible SpO2 from 1% to 100%). The result is a Discrete Saturation Transform (DSTTM) plot
of Relative output power versus possible SpO2 value as shown in the following figure, where R corresponds to SpO2
= 97%.
Relative
The red light power range is 1mw to 3 mw.
The infrared light power range is 0.7mw to 3mw.
64
Vital-Guard 450C Operation and Maintenance Manual
MASIMO SET® PULSE OXIMETRY MONITORING
The DST plot has two peaks: the peak corresponding to the higher saturation is selected as the SpO2 value. This
entire sequence is repeated once every two seconds on the most recent four seconds of raw data. The Model 450C
SpO2 therefore corresponds to a running average of arterial hemoglobin saturation that is updated every two seconds.
WARNING: The pulse oximeter should NOT be used as an apnea monitor.
WARNING: The pulse oximeter should be considered an early warning device. If a trend towards patient
deoxygenation is indicated, blood samples should be analyzed by a laboratory co-oximeter to completely
understand the patient’s condition.
Caution: Use only sensors specified by Ivy Biomedical Systems, Inc. If you use sensors other than those
manufactured by the Masimo corp., it might degrade performance and could damage the pulse oximeter.
Caution: Tissue damage can be caused by incorrect application or use of the sensor. Check the sensor site
frequently. Do not allow the sensor to remain on one site for a prolonged period of time, especially when
monitoring neonates. Refer to the sensor’s specific instructions.
Caution: Never attach a SpO2 sensor on a limb being monitored with a blood pressure cuff or a limb with
restricted blood flow.
Caution: A poorly applied sensor might give incorrect saturation values. Reapply the sensor.
Caution: Choose a site with sufficient perfusion to ensure accurate oximetry values.
Caution: Certain nail aberrations, nail polish, fungus, etc. might give inaccurate oximetry values
Caution: Do not use the Model 450C Pulse Oximeter or sensors during Magnetic Resonance Imaging (MRI).
Pulse Oximetry Sensors
To ensure conformance with all safety and performance specifications, use only the recommended pulse oximetry
sensors.
Monitoring Procedure
Use the following procedure for monitoring pulse oximetry:
1.
Choose a site that is well perfused and provides proper alignment of the LEDs and receiving photodetector
Select a site that has unrestricted blood flow
Do not restrict blood flow when securing sensor with tape
Select an appropriate sensor and apply it to the patient, following the directions for use provided with the sensor
Do not select a site near potential electrical interference (electrical cords, for example).
2.
Connect the cable to the monitor’s SpO2 input.
3.
Plug the sensor into the extension cable.

Pulse Oximetry with ECG Off
When you are monitoring oxygen saturation but not ECG, set the ECG/HR menu setting to OFF to inhibit unwanted
LEAD OFF alarms. With these settings, the heart rate on the display is derived from the pulse waveform and has a
flashing pulse symbol for each detected heartbeat.
Use the following procedure to set ECG to OFF.
1.
Press the PATIENT SETUP key to display the main menu. Select [ECG/HR] to display the ECG/HR menu.
2.
Use the [ECG] selection to set ECG to off. When ECG is off, heart rate can be computed from the pleth
waveform.
NOTE: To set heart rate limits when using any heart rate source, use the ALARM SETUP menus as described in the
ECG Monitoring section of this manual.
Pulse Oximetry Considerations
If the accuracy of any measurement does not seem reasonable, first check the patient’s vital signs by alternate means
and then check the Model 450C Pulse Oximeter for proper functioning.
NOTE: The waveform displayed by the SpO2 signal is not proportional to the pulse volume.
Inaccurate measurements may be caused by:
•
Incorrect sensor application or use
•
Significant levels of dysfunctional hemoglobin (e.g., carboxyhemoglobin or methemoglobin) – see note.
•
Intravascular dyes such as indocyanine green or methylene blue – see note.
•
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 corrected by covering the sensor with a dark or opaque material)
•
Excessive patient movement
•
Venous pulsations
•
Placement of a sensor on an extremity with a blood pressure cuff, arterial catheter, or intravascular line
The Model 450C can be used during defibrillation, but the readings may be inaccurate for a short time.
Loss of pulse signal can occur in any of the following situations:
•
The sensor is too tight
•
There is excessive illumination from light sources such as a surgical lamp, a bilirubin lamp or sunlight
•
A blood pressure cuff is inflated on the same extremity as the one with a SpO2 sensor attached
•
The patient has hypotension, severe vasoconstriction, severe anemia, or hypothermia
•
There is arterial occlusion proximal to the sensor
•
The patient is in cardiac arrest or is in shock
NOTE: A pulse oximeter measures functional hemoglobin saturation. This is different to an arterial blood gas that
measures fractional hemoglobin saturation. Differences can occur when significant levels of HbCO
(carboxyhemoglobin), HbMET (methomoglobin) indocynanine green or methylene blue exist.

NIBP MONITORING
NIBP MONITORING
General Description
The Model 450C uses the oscillometric method for measuring non-invasive blood pressure (NIBP). The monitor
automatically inflates and then slowly deflates the pressure cuff. Pressure fluctuations from the arterial pulse are
detected by the monitor and used to determine the systolic, diastolic, and mean pressure. The monitor displays
numeric values for this measurement on the left side of the monitor. No waveform is displayed.
For proper NIBP monitoring, use the accessories listed in the Accessories section of this manual.
NIBP has three modes of operation: manual, automatic, and stat. Press the CYCLE key to set the desired mode. In
manual mode, a single measurement is taken by pressing the START key. Automatic mode generates measurements
at regular intervals until the STOP key is pressed. Intervals are programmable for 1, 2, 3, 4, 5, 10, 15, 20, 30, or 60
minutes.
In STAT mode, pressing the START key initiates a series of measurements taken for a five-minute period.
A tabular display shows data as it is measured at the time of each NIBP reading. The display contains columns for
time of day; systolic, diastolic, and mean NIBP; peripheral pulse measured from the NIBP cuff; respiration rate;
SaO2; invasive blood pressures and temperature. The latest four readings are displayed, and a scrolling procedure
allows you to display previous readings.
NIBP Monitoring Considerations
•
Do not use this device on a patient who has an artificial heart or lung.
•
Measurement might be impossible in case of continuous noise or when the patient’s pulse is highly irregular.
•
When this device is used to measure the blood pressure of critically conditioned patients, the pressures should
be measured again by stethoscope or palpation if the indicated values are doubted.
•
Since the pulse rate is measured at a distal part of the body, it might be different from the rate computed from
the ECG.
•
Use of the correct size cuff and proper wrapping help ensure accurate measurements.
•
Do not restrict or compress the external tubing.
•
Compression of the cuff or hose can cause noise, which might interfere with the measurement.
•
Try to keep the patient relaxed and quiet during the measurement. Muscle tension or talking can interfere with
the measurement.
•
Check to be sure that use of the equipment does not result in prolonged impairment of the circulation of the
patient.
•
The repeated use of the Short Term Automatic Mode (STAT MODE) for more than five minutes can caused
tissue damaged.

NIBP MONITORING
Cuff Placement
Proper cuff size and placement are essential to assure accurate blood pressure measurement.
The American Heart Association recommends that cuff sizes should be at a length-to-width ratio of about 2:1,
ensuring that if the bladder width is 40% of the arm circumference, the bladder length will encircle 80% of the arm.
Also, care should be taken to center the bladder directly over the brachial artery.
Cuff too narrow
Cuff proper width
On the left, the bladder width is small for the arm, and full cuff pressure is never applied to the artery which can
caused an erroneously high pressure result. On the right, the bladder width is adequate for the arm, and full cuff
pressure is applied to the brachial artery.
Cuffs for thighs are available for large patients or those where neither arm is available for cuff placement. Blood
pressure measured at the thigh is typically 20-30 mmHg higher than blood pressure measured at the upper arm.
Monitoring Procedure
1.
Connect the air hose fitting to the NIBP connector on the monitor’s side panel. To remove move the sleve
back and pull the air hose.
Also connect the other end of the air hose to the cuff fitting.

2.
Apply the cuff to the patient as follows.
•
Wrap the cuff snugly, with room between the cuff and arm for two fingers. If the cuff is wrapped too
loosely, it cannot be inflated properly causing possible errors in measured values.
•
Wrap the bare arm when possible. If clothing oppresses the arm, measured values might not be reliable.
The end of the cuff should fall inside the range marked on the inside of the cuff. If it doesn’t, use a different
size cuff.
Heart
Cushion
•
Keep the cuffed part of the arm at the same level as the heart. If it is above the level of the heart the blood
pressure measurement will be lowered. If it is below the heart level, the blood pressure will be raised (due
to the physical weight of the blood).
•
Do not compress the cuff or the rubber hose externally. Compression of the cuff or the rubber hose will
cause measurement error. Rest the arm on a cushion to prevent compression against the body.
•
Keep the patient as still as possible during the measurement.
WARNING: Always check the mode setting before starting an NIBP procedure. Monitoring a neonate in adult
mode can cause injury to the patient.
3.
Select the NIBP monitoring mode as described in the following procedures.
4.
Press the START key to initiate measurements.
5.
Press STOP/DEFLATE to deflate the cuff and end all NIBP procedures.
If the monitor cannot obtain a valid reading in manual mode, it displays a small number 1 near the NIBP mean value
display and repeats the measurement. The monitor might try up to four measurements, depending on the problem,
until a valid reading is obtained, displaying the number of tries after each measurement.
After several unsuccessful tries, the monitor cancels the measurement and displays the CHK CUFF alarm message.
NIBP Graph
To display the NIBP graph, press the PATIENT SETUP key, select [NIBP], and select [DATA FORMAT] until it
is set at GRAPH.
The oscillation profile assists the clinician in determining the validity of the NIBP measurement. An erratic or flat
profile suggests that excessive motion or other artifact may have affected the measurement. A profile shaped like a
bell curve represents a measurement not affected by motion or other artifact.
