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 SpO
2
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 SpO
2
levels between 1% and 100%. When SpO
2
levels are
between 70% and 100%, oximeter measurements are accurate within ±3 digits. When the pulse
oximeter measures SpO
2
levels less than 50%, the display shows < 50%.
To measure the patient’s SpO
2
levels:
1 Connect the SpO
2
cable to the monitor.
2 Attach the sensor to the SpO
2
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 SpO
2
volume as necessary.

Waveform
The SpO
2
waveform can be displayed on waveform Channel 2 by selecting waveform Channel 2
and then selecting SpO
2
from the Waveform menu. The SpO
2
waveform automatically sizes itself
to provide optimum waveform viewing.

The following overlay appears:
1 Highlight and select SPO2 VOLUME .
2 Rotate the Speed Dial to the desired
volume.
3 Press the Speed Dial to set the
volume.
