 and special features

There are multiple configuration settings associated with this parameter. Refer 
to the following table for details and then configure as necessary.

This feature uses acoustic technology to continually measure a patient's respiration 
rate based on airflow sounds generated during the breathing cycle of inspiration and 
expiration.

This feature alerts for an increasing quantity of smaller desaturations that may not 
exceed the low SpO

2

 alarm threshold and that may provide an early indication that 

the patient's respiratory status is declining. The user enters the period of time over 
which to look at desaturations, desired delta threshold (% from baseline), and number 
of desaturations before being alerted.

Current number of desaturations is displayed by Desaturation Index. The number of 
Desat Occurrences can be reset by 1) adjusting the Desat Threshold, or 2) removing 
the sensor from the patient or the monitor.

Options:

•

Desat Occurrences can range from 1 to 24.

•

Desat Threshold range change from 2-10% in 1% increments.

•

Desat Time period range from 1 to 4 hours in 1 hr increments.

Configure in Alarm Setup or Monitor Setup > Advanced > Default Setup > Alarm 
Defaults.

FastSat enables rapid tracking of arterial oxygen saturation changes. Arterial oxygen 
saturation data is averaged using pulse oximeter averaging algorithms to smooth the 
trend.

FastSat is always on when 2 - 4 and 4 - 6 averaging modes are activated.

FastSat is not recommended for routine use as the increased fidelity of this mode may 
also increase the frequency of alarms caused by rapid but transitory changes in SpO

.

FastSat enables rapid response to, and display of, fast changes in SpO

 by giving 

priority to the most recent data.

During some seizures, oxygen levels may drop to dangerous levels. SpOC is a non-
invasive measure of the total oxygen content present in the blood. 

The Perfusion Index (PI) is the ratio of the pulsatile blood flow to the non-pulsatile or 
static blood in peripheral tissue. PI thus represents a noninvasive measure of 
peripheral perfusion that can be continuously and noninvasively obtained from a 
pulse oximeter.
