Using SatSeconds

Overview

N-600x Operator's Manual
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 audible alarm immediately sounds. When
the %SpO level fluctuates near an alarm limit, the alarm sounds
2
each time the limit is violated. Such frequent alarms can be
distracting.
The N-600x pulse oximeter utilizes Nellcor SatSeconds alarm
management technique. With the SatSeconds technique, upper
and lower alarm limits are set in the same way as with traditional
alarm management. The clinician also sets a SatSeconds limit that
allows the monitoring of %SpO
limit for a period of time before an audible alarm sounds.
The SatSeconds limit controls the time that the %SpO
fall outside the alarm before an audible alarm sounds.
The method of calculation is as follows:
The number of percentage points that the %SpO
the alarm limit is multiplied by the number of seconds that the
%SpO level remains outside that limit. This can be stated as an

equation:
Points x Seconds = SatSeconds
Where:
Points = %SpO percentage points outside of the limit

Seconds = number of seconds the %SpO
that point outside of the limit
