Methodology
Averaging Time (Masimo Technology Only)
This menu option only appears when using Masimo Technology and sensor. Choose
a response time in order to compensate for different levels of patient activity: 2, 4, 8,
10, 12, 14, or 16 seconds.
For the 2 and 4 second averaging settings: The actual averaging times may range
from 2 to 4 and 4 to 6 seconds, respectively.
 10, 12, 14, or 16 seconds: These averaging settings are least affected by patient
movement.
 8 seconds: This averaging selection is recommended in cases where the patient
is relatively inactive.
 2 or 4 seconds: These averaging selections are most affected by patient movement.
Print Interval
This setting determines the time interval for printing the MSpO
2
values on the strip
chart paper.
%O
2
Trace
This setting enables or disables the printing of the MSpO
2
trend on the bottom grid
of the strip chart paper.
 On: The MSpO
2
trend prints in grey and is annotated with MSpO
2
.
 Off: The MSpO
2
trend is not printed.
Alarms
These fields adjust the high and low alarm limits for MSpO
2
, as well as for MHR/
P—in increments of 1% or 5 bpm. The selectable values are listed in Chapter 10,
“Alarms.” Refer to Appendix A, “Factory Defaults” for additional information.
Alarm Volume
This field controls alarm volume for all maternal alarms.
Refer to “Factory Defaults” on page A-1 for information on factory defaults and
setting options.
MSpO
2
Methodology
The maternal oxygen saturation is indicated by up to three digits representing the
percentage of oxygen saturation. The pulse amplitude indicator is a vertical bar that
visually indicates each pulse.
When MSpO
2
monitoring is employed, the MSpO
2
pulsatile (plethysmograph)
waveform can be displayed and printed. Refer to Chapter 14, “Waveforms” for more
information.
