Nellcor OXIMAX SpO2: Buttons Associated with SpO2
SatSeconds™
With traditional alarm management, upper and lower alarm limits are set for
monitoring SpO
2
. 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
fluctuates near an alarm limit, the alarm sounds each time the limit is
violated. To prevent these nuisance alarms, the V100 Monitor uses the
SatSeconds
technique. The SatSeconds technique ( SAt ) controls the time that the % SpO
2
level
may fall outside the alarm before an audible alarm sounds. Choose either
0, 10,
25, 50,
or 100 seconds. If 0 is chosen this limit hold-off feature is disabled.
The SatSeconds number is calculated by taking the amount the current
saturation value is out of limits and multiplying it by the amount of time it has
been out of those limits. For example: if the lower limit is set to 95% and the
patient's saturation is 90%, the amount out of limit is 5%. If the SatSeconds
feature is set to 50, the alarm would sound in 10 seconds, because 5%
saturation (out of limits) multiplied by 10 seconds (time out of limit) equals 50
SatSeconds.
The SatSeconds “Safety Net” is for patients with saturation levels having frequent
excursions below the limit, but not staying below the limit long enough for the
SatSeconds time setting to be reached. When 3 or more limit violations occur
within 60 seconds, an alarm sounds even if the SatSeconds time setting has not
been reached.
Buttons Associated with SpO
2
There are no buttons associated with this parameter.
Windows Associated with SpO
2
There is one window associated with this parameter: SpO
2
. While in offline
mode, nothing is displayed in the SpO
2
window. When in ready mode and the
parameter senses that a sensor is connected, a single dash (-) appears in this
window. When it is in operate mode and the parameter is reporting valid data,
the derived SpO
2
value appears in this window and updates continuously. The
values are displayed in %.
NOTE: If SpO
2
is the source for pulse rate, the Pulse Rate window is associated
with this parameter. Refer to the “Pulse Rate” Section for more
information.
Indicators Associated with SpO
2
There is one indicator associated with this parameter: the pulse amplitude
indicator bar. The red LED bar flashes to indicate that pulse rate measurements
are being derived from SpO
2
signals and the height of the bar is proportional to
the arterial blood flow.
