7.5 Changing SpO
2
Settings
7.5.1 Accessing SpO
2
Menu
By selecting the SpO
2
parameter or waveform area, you can access the [ SpO2 Setup ]
menu.
7.5.2 Adjusting the Desat Alarm
The Desat alarm is a high level alarm notifying you of potentially life threatening drops in
oxygen saturation.
Select [ Alarm Setup >> ] from the [ SpO2 Setup ] menu. From the pop-up menu, you can
set low alarm limit and alarm switch for [ Desat ]. When the SpO
2
value is below the Desat
alarm limit and Desat alarm switch is set to [ ON ], the message [ SpO2 Desat ] is displayed.
7.5.3 Setting SpO
2
Sensitivity
For Masimo SpO
2
module, you can set [ Sensitivity ] to [ Maximum ] or [ Normal ] in the
[ SpO2 Setup ] menu.
When monitoring neonatal or non-critically ill patients who tend to move a lot, noise or
invalid signals may be caused. In this case, it is recommended that the sensitivity is set to
[
Low ] or [ Normal ] so that the interference caused by motion can be filtered and
therefore the measurement stability can be ensured.
7.5.4 Changing Averaging Time
The SpO
2
value displayed on the monitor screen is the average of data collected within a
specific time. The shorter the averaging time is, the quicker the equipment responds to
changes in the patient’s oxygen saturation level. Contrarily, the longer the averaging
time is, the slower the equipment responds to changes in the patient’s oxygen
saturation level, but the measurement accuracy will be improved. For critically ill
patients, selecting shorter averaging time will help understanding the patient’s state.
To set the Masimo SpO
2
averaging time, select [ Averaging ] in the [ SpO2 Setup ] menu
and then toggle between [ 2-4 s ], [ 4-6 s ], [ 8 s ], [ 10 s ], [ 12 s ], [ 14 s ] and [ 16 s ].
7.5.5 Monitoring SpO
2
and NIBP Simultaneously
When monitoring SpO
2
and NIBP on the same limb simultaneously, you can switch
[ NIBP Simultaneous ] on in the [ SpO2 Setup ] menu to lock the SpO
2
alarm status until
the NIBP measurement ends. If you switch [ NIBP Simultaneous ] off, low perfusion
caused by NIBP measurement may lead to inaccurate SpO
2
readings and therefore cause
false physiological alarms.
