SatSeconds Alarm Management
The N-550 utilizes Nellcor’s SatSeconds alarm management technique.
SatSeconds is a function of the software within the N-550. With the
SatSeconds technique, upper and lower alarm limits are set in the same way as
traditional alarm management. The clinician also sets a SatSeconds limit that
allows monitoring of %SpO
2
below the selected lower alarm limit for a period
of time before an audible alarm sounds. Refer to the N-550 Operator's manual
for managing
SatSeconds .
