Inaccurate SpCO and SpMet Readings
Very low arterial oxygen saturation levels may cause
inaccurate SpCO and SpMet readings.
The Pleth Waveform
You can display the plethysmographic (pleth) waveform in Channel 2 or 3.
To display the pleth waveform:
1. Rotate the
SPEED DIAL
to outline waveform
CHANNEL 2
or
3
.
2. Press the
SPEED DIAL
. The Channel menu appears.
3. Select
WAVEFORM
and then select
SPO2
. The SpO
2
waveform appears in the selected
channel. The waveform is automatically sized for optimum waveform viewing.
Volume
To adjust the pulse tone volume:
1. Rotate the SPEED DIAL to outline the
SpO
2
area on the Home Screen.
2. Press the SPEED DIAL .
3. Highlight and select
SPO2 VOLUME
.
4. Rotate the
SPEED DIAL
to the desired
volume.
5. Press the
SPEED DIAL
to set the
volume.
Sensitivity
The sensitivity setting allows you to adjust the oximeter to either
NORMAL
or
HIGH
for
differing perfusion states.
To adjust sensitivity:
1. Outline and select the SpO
2
area on the Home Screen.
2. Select
SENSITIVITY
and then select
NORMAL
or
HIGH
.
Note:
NORMAL
sensitivity is recommended for most patients. The
HIGH
sensitivity setting
allows SpO
2
monitoring under low perfusion states, such as the severe hypotension of shock.
However, when SpO
2
sensitivity is set to
HIGH
, the signal is more susceptible to artifact.
Monitor the patient closely when using the
HIGH
sensitivity setting.
