Settings
Changing the SpO
2
Sensitivity Mode
The Sensitivity Mode setting determines how quickly the monitor reports changes in
SpO
2
values by controlling the averaging algorithm used to calculate the SpO
2
value.
Note
If your system administrator has specified an SpO
2
alarm delay time, consider the total
possible delay time when selecting the Sensitivity Mode setting. For more information,
see “SpO
2
Alarm Delay” on page 5-9.
To change the SpO
2
sensitivity mode
1 Touch the SpO2 numeric pane.
The SpO2 menu appears, displaying the current settings.
2 Touch the Sensitivity Mode menu and select one of the following:
- Slow — Use this setting when motion artifact is an issue. SpO
2
changes are
reported every 20 seconds.
- Normal — Use this setting for most monitoring situations. Changes are reported
every 10 seconds.
- Fast — Use this setting for special applications (for example, sleep studies) when
you need a fast response. Changes are reported every 5 seconds. Do not use the
Fast setting if motion artifact is an issue.
3 Touch Done.
Depending on the magnitude of difference between the alarm limit and the displayed
value, the alarm signal generation delay may be from 1 second to the value of the
response time (5, 10, or 20 seconds), plus any additional configured alarm delay time. If
an SpO2 Extd Update technical alarm occurs, the physiological alarm response time is
proportionately longer. If the monitor is configured for SpO2 High/Low Alarm Delay, the
alarm generation is delayed by the configured time.
If the total delay in response time exceeds 30 seconds, the SpO2 numeric pane
alternates between displaying the SpO
2
value and displaying -?-.
