Sets the Sat-Seconds limit.
When Sat-Seconds reaches or exceeds the set limit,
the low SpO
2
alarm is triggered.
If SpO
2
measurement fluctuates outside the set limit
for three times within 1 minute, the low SpO
2
alarm
will be triggered even though the set Sat-Seconds
limit is not reached.
The Sat-Seconds function does not affect the Desat
alarm. Once the SpO
2
is below the Desat limit, the
Desat will be triggered.

Sat-Seconds (Nellcor only) is calculated as follows:
where,
n represents the number of SpO
2
values that falls outside the alarm limit.
SpO
2
(i) represents each SpO
2
value that violates the alarm limit.
SpO
2
(lim) represents the corresponding high or low alarm limit.
t (i) is the time that SpO
2
(i) lasts, and the unit is s.
