Technical Information
N-560 Operator’s Manual 87
SatSeconds Display
When the N - 560 SatSeconds technology detects an SpO
2
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 SatSeconds 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 SatSeconds 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 - 560 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.
The SatSeconds limit controls the time that the %SpO
2
level may fall
below the alarm limit before an audible alarm sounds.
