Overview (90343 only)
Pulse oximetry enables you to noninvasively monitor a patient’s hemoglobin
oxygen saturation either continuously or episodically. The oximetry sensor
contains two light emitting diodes (LEDs) that transmit specific wavelengths
(approximately 660 and 940 nanometers) of light that are received by a
photodetector.
Oxygen saturated blood absorbs light differently than unsaturated blood. Thus,
the amount of light absorbed by the blood can be used to calculate the ratio of
oxygenated hemoglobin to total hemoglobin in arterial blood. This ratio is
displayed as percent SpO
2
. Normal values range from 95 to 100%.

Monitoring
The 90343 digital telemetry multi-parameter transmitter uses Spacelabs Medical
sensors as well as those from other manufacturers.
Refer to Accessories on page -47 for information concerning specific sensors.
WARNING:
• A pulse oximeter should NOT be used as an apnea monitor.
• A 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.
!
• With the Module Configuration Manager feature, you can define
your own default settings for characteristics such as alarm limits
and display configuration. Refer to the Module Configuration
Manager chapter in this manual for further details.

N:
• Use only patient sensors specified by Spacelabs Medical.
Using sensors other than those specified may degrade
performance and damage the transmitter during
defibrillation.
• Check the sensor site frequently. Do not allow the sensor
to remain on one site for a prolonged time, especially when
monitoring neonates. Refer to the sensor manufacturer's
instructions.
• Never attach an SpO
2
sensor on a limb being monitored
with a blood pressure cuff or a limb with restricted blood
flow.
• A poorly applied sensor may give inaccurate saturation
values.
• Choose a site with sufficient perfusion to ensure accurate
oximetry values.
To set up SpO
2
monitoring:
1 Open the battery cover and
remove the battery
2 Confirm that the DIP switches 1
through 8 are in the correct
setting (Switch 7 must be set to
ON for neonatal use and to OFF
for adult use)
3 Reinstall the battery and close
the battery cover
4 Connect the SpO
2
adapter
cable (P/N 700-0014-00) to the
transmitter
5 Attach the sensor to the patient
and connect the sensor cable to
