The SatSeconds Safety Net
The SatSeconds “Safety Net” is for patients with saturation levels frequently
below the limit, but not staying below the limit long enough for the SatSec-
onds time setting to be reached. When three or more limit violations occur
within 60 seconds, an alarm sounds even if the SatSeconds time setting has
not been reached.
3.7.3
OxiMax SPD™ Alert Parameter

WARNING:
Supplemental oxygen will attenuate patterns of desaturation. A patient’s
respiratory compromise can be proportionally more severe before patterns
appear in the saturation trend. Remain vigilant when monitoring a patient on
supplemental oxygen.

Caution:
Do not modify any other alarm settings while using the SPD parameter.
The OxiMax SPD™ Alert (SPD) method of detecting patterns of desaturation in
adults is a function of the software within the monitoring system, which
detects repetitive occurrences of desaturation followed by resaturation. These
patterns are indicative of repetitive reductions in airflow through the upper
airway and into the lungs. With the SPD parameter enabled, the default value
for SatSeconds alarms is 100.
