Monitoring SpO2, SpCO, and SpMet
Volume
To adjust the pulse tone 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.
Averaging Time
Averaging time allows you to adjust the time period that is used to average the SpO
2
value.
To adjust averaging time:
1. Outline and select the SpO
2
area on the Home Screen.
2. Select
AVERAGING TIME
and then select one of the following:
• 4 Seconds
• 8 Seconds
• 12 Seconds
• 16 Seconds
Note:
Averaging time of 8 seconds is recommended for most patients. For patients with rapidly
changing SpO
2
values, 4 seconds is recommended. Use a 12- or 16-second time period when
artifact is affecting the performance of the pulse oximeter.
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.
