11.11 SatSeconds Alarm Management*
* Only applicable to the Nellcor SpO
11.11.1 Describing SatSeconds
With traditional alarm management, upper and lower alarm limits are set for monitoring oxygen
saturation. During monitoring, as soon as an alarm limit is violated by as little as one percentage
point, an alarm is immediately triggered. When the SpO
alarm is triggered each time the limit is violated. Such frequent alarms can be distracting.
With the SatSeconds technique, upper and lower SpO
