Specifying the SpO
2
Averaging Time
The Masimo SpO
2
module in the X Series unit provides three different time periods over which
SpO
2
values are averaged: 4 seconds, 8 seconds (default) and 16 seconds. The averaging period
is rarely changed from the 8 second default setting. For high risk patients with rapidly changing
SpO
2
conditions, use the 4 second setting. Use the 16 second setting only when the 8 second
setting (default) is inadequate due to extremely high artifact conditions.
Selecting the SpO
2
Sensitivity
You can select either normal or high sensitivity for SpO
2
monitoring. The Normal sensitivity
setting is recommended setting for most patients. The High sensitivity setting allows you to
monitor SpO
2
even under very low perfusion conditions. Such conditions may include severe
hypotension or shock. With the High sensitivity setting, however, SpO
2
results are more easily
contaminated by artifact. To ensure accurate SpO
2
readings when using the High sensitivity
setting, observe the patient carefully and continuously.
Selecting the Heart Rate/ Pulse Rate (HR/PR) Tone
The unit allows you enable or disable the tone that the monitor uses to indicate detection of the
patient’s pulse:
On
or
Off
(no tone sounds). The default tone is
Off
.
