3-12 LIFEPAK 20e Defibrillator/Monitor Operating Instructions
SpO2 Monitoring Procedure
The defibrillator controls power to the pulse oximeter. When the defibrillator is turned on, the
oximeter turns on and performs a self-test that requires up to 10 seconds. When the defibrillator
is turned off, the oximeter also turns off.
To conserve battery power, the pulse oximeter goes into “sleep mode” when not in use. Sleep
mode is activated within 10 seconds of disconnecting the sensor. During sleep mode, the screen
does not display SpO2 information. The oximeter returns to normal mode after detecting a sensor
or a patient signal. The oximeter performs the self-test when it returns from sleep mode to active
mode.
The pulse oximeter measures SpO2 levels between 1% and 100%. When SpO2 levels are
between 70% and 100%, oximeter measurements are accurate within ±3 digits. When the pulse
oximeter measures SpO2 levels less than 50%, the display shows < 50%.
To measure the patient’s SpO2 levels:
1 Connect the SpO2 cable to the monitor.
2 Attach the sensor to the SpO2 cable and the patient.
3 Press
ON.
4 Observe the pulse bar for fluctuation. Amplitude of the pulse bar indicates relative signal
quality.
5 Adjust sensitivity, averaging time, and SpO2 volume as necessary.
SpO2 Waveform
The SpO2 waveform can be displayed on waveform Channel 2 by selecting waveform Channel 2
and then selecting SpO2 from the Waveform menu. The SpO2 waveform automatically sizes
itself to provide optimum waveform viewing.
SpO2 Volume
To adjust the pulse tone volume, highlight and select SPO2 on the home screen.
The following overlay appears:
Sensitivity
The sensitivity setting allows you to adjust the oximeter for differing perfusion states. To adjust
the sensitivity to either normal or high, highlight and select
SPO2 on the home screen and then
select
SENSITIVITY.
1 Highlight and select SPO2 VOLUME.
2 Rotate the Speed Dial to the desired
volume.
3 Press the Speed Dial to set the
volume.
