SatSeconds Display
When the N-560 SatSeconds technology detects an SpO2 value
outside the alarm limit, the SatSeconds indicator LEDs begin to light
(fill) clockwise. When the SpO
2 value is within the set limits, the
SatSeconds indicator LEDs will extinguish counterclockwise.
When all of the SatS
econds indicator LEDs are lit, indicating that the
SatSeconds setting has been reached, an audible alarm sounds and
the SatSeconds indicator LEDs flash. As with traditional alarm
management, the audible alarm may be silenced by pressing the
Alarm Silence button.
Note: When a SatSecon
ds setting other than OFF is selected, the
green LED at the top of the SatSeconds indicator will light. The
green LED indicates that SatSeconds have been engaged.
Describing SatSeconds
With traditional alarm management, upper and lower alarm limits are
set for monitoring oxygen saturation. During monitoring, as soon as
an alarm limit is violated by as little as one percentage point, an
audible alarm immediately sounds. When the %SpO
2 level fluctuates
near an alarm limit, the alarm sounds each time the limit is violated.
Such frequent alarms can be distracting.
The N-56
0 utilizes Nellcor SatSeconds alarm management. With the
SatSeconds technique, upper and lower alarm limits are set in the
same way as traditional alarm management. However, the clinician
also sets a SatSeconds limit that allows monitoring of %SpO
2 below
the selected lower alarm limit and above the selected upper alarm
limit for a period of time before an audible alarm sounds.
