Figure 6: Alarm Response with SatSeconds
Saturation levels may fluctuate rather than remaining steady for a
period of several seconds. Often, %SpO
2 levels may fluctuate above
and below the alarm limit, reentering the non-alarm range several
times.
During such fluctuation, the N-560
integrates the number of %SpO2
points, both positive and negative, until either the SatSeconds limit
(SatSeconds setting) is reached, or the %SpO
2 level returns within a
normal range and remains there.
SatSeconds “Safety Net”
The SatSeconds “Safety Net” is for patients whose saturation levels
frequently go below the limit but do not stay below the limit long
enough for the SatSeconds setting to be reached. When 3 or more
limit violations occur in 60 seconds, an alarm will sound even if the
SatSeconds setting has not been reached.
