Figure 13: Alarm Response With Satseconds - Nellcor OxiMax N-595 Operator's Manual

SatSeconds
136
The alarm response time, assuming a SatSeconds limit set at 50 and a
lower alarm limit set at 90, is described and illustrated below.
In this example, the %SpO
there for a period of 2 seconds (2 points x 2 seconds = 4 SatSeconds).
The %SpO then drops to 86 for 3 seconds and then to 84 for 6
2
seconds. The resulting SatSeconds are:
%SpO2
2 x
4 x
6 x
After approximately 10.9 seconds the SatSeconds alarm would sound,
because 50 SatSeconds had been exceeded. See the arrow (!) in
Figure 13 on page 136.
