and then press SHOW. The HELP SPD window appears.The Saturation Pattern
Detection (SPD) help topic contains a total of ten (10) consecutive help windows.
Press the NEXT softkey to scroll through each window of the selected help topic
for the following information:
“Saturation Pattern Detection detects repetitive patterns of desaturation in the
trend in adults. Caregivers are alerted to these patterns via a visual indicator, and
optionally, an audio alarm. The triangle icon for Saturation Pattern Detection
appears on the monitor display when the feature is enabled. The triangle fills from
the bottom to the top as patterns become more severe and empties from top to
bottom as the patterns become less severe. If the triangle fills, an alarm sounds.
With Saturation Pattern Detection enabled, the default setting is On with the
sensitivity set to 1. The feature can be turned off in the LIMITS menu. Caregivers
can select from three alarm sensitivity settings: 1 (most sensitive), 2 (medium
sensitivity) or 3 (least sensitive), with 1 resulting in more alarms and 3 resulting in
fewer alarms.
Enabling Saturation Pattern Detection automatically activates the SatSeconds feature.
The TREND key blinks when a Saturation Pattern Detection alarm occurs. If the
alarm is resolved, the TREND key stops blinking but remains highlighted until the
caregiver presses it to view the event or clears it by pressing the TREND key.”
