Module
1. Apply the SpO
2
sensor to the patient. Insert the patient's forefinger into the probe
as far as it will go, and make sure that the finger tip covers all of the probe window.
This is to prevent that extraneous light reaches the photodetector.
2. Connect the SpO2 sensor to the device and secure the cable with the two velcro
fasteners.
3. Check the bar graph for signal quality (1) .
4. Check Perfusion Index PI level (3).
5. Set the narrow SpO
2
alarm limit see page 40.
6. When the SpO2 value exceeds the alarm limit (2) , an alarm is issued.
Set the alarm limit to narrow or wide when the vital data are not critical.
Perfusion Index PI (3) with trending capability indicates arterial pulse signal strength
and may be used as a diagnostic tool during low perfusion.
PI display ranges from 0.02% (very weak pulse strength) to 20% (very strong pulse
strength).
Display “-?-” or “---” instead of the value:

--- Sensor not connected to the device

-?- Sensor not attached to finger

measurement field
MENU Parameter Description Value
SpO2 HR Source
a
Source based on which the heart rate
should be determined.
a. When the patient has a cardiac pacemaker, the HR source must be set to Pleth (see page 46 ).
Auto , Defi, ECG or Pleth
If set to Auto, the device will
automatically switch sources with
following priority: DEFI > ECG > Pleth
Average
Definition of the integration time for the
calculation of the displayed average value.
4/6/ 8 /10/12/14/16 seconds
Sensitivity
Select the measurement sensitivity. Select
High when the pulse is weak. APOD
(Adaptive Probe off detection) is optimised
for the detection of “Sensor has come off”,
regardless of the signal quality. The setting
"High" must not be set as default setting.
Normal, Maximum, Adaptive Probe
Off detection
If set to “Maximum” and the sensor
becomes dislodged from the patient,
the potential for false readings may
occur due to environmental "noise"
such as light, vibration, and excessive
air movement.
Line Frequency
Set to match regional power line frequency
to allow for cancellation of noise introduced
by fluorescent lights and other sources.
50 or 60 Hz
SpO2 Sound level
Set the pulse tone. The pitch of the pulse
tone also indicates if the saturation level is
high (high pitch) or low (low pitch).
OFF, low, medium, high
