in SpO2. For example, set the intelligent alarm range as 50, the upper limit of NELLCOR SpO2 alarm as
97%, and lower limit as 90%, the measured SpO2 value turns out to be 80% and remains for 3 seconds, then, it
decreases to 78% and remains for 2 seconds, so calculating from the time the alarm limit is exceeded, the
sound-light alarm will initialize instantly only when the SpO2 value is out of the alarm range for 5 seconds.
Meanwhile , the circle beside the SpO2 value returns to origin. Its calculation is as follow:
Minus percentage points x seconds = SatSeconds integer
values of the calculated SatSeconds are shown:
%SpO2
(90%-80%) x
(90%-78%) x
Total SatSeconds
SatSeconds Example:
After about 4.9 seconds, the instrument will report SatSeconds alarm, because 54 is beyond the intelligent
alarm range 50 SatSeconds.
Within a few seconds , saturation will fluctuate a bit, and not be stable. Generally, the patient's SpO2 value
may fluctuate between the upper and lower limits of the alarm, and may re-enter to non-alarm range several
times. In this volatile period, the system will store the positive and negative points of the SpO2, till it reaches
the SatSeconds limit or patient's SpO2 values returned to and remains in the non-alarmrange.
