Setting the SpO
2
Averaging Period
The R Series provides three different time periods over which SpO
2
values are averaged:
• 4 seconds
• 8 seconds (factory default)
• 16 seconds
The averaging period is rarely changed from the 8-second default setting. For high-risk patients
with rapidly changing SpO
2
conditions, use 4-second averaging. The 16 second setting should
be used only when the 8-second setting (default) is inadequate due to extremely high artifact
conditions.
To set the SpO
2
averaging period:
1. Press the Average key.
The following softkeys appear: 4 secs, 8 secs, 16 secs.
2. Press the softkey for the preferred averaging period, then press the Return softkey.
Displaying the Plethysmogram
When pulse oximetry is in use, the unit can display a plethysmogram below the ECG in either
the second or third trace position in MONITOR and DEFIB mode (for ALS models) or ON
mode (for Plus and BLS models), or in the second trace position in PACER mode (for all
models).
To display or remove the plethysmogram:
1. From one of the following modes:
• MONITOR, DEFIB or PACER mode for ALS models
• ON or PACER mode for Plus or BLS models
2. Press the Options softkey.
3. Press Traces.
4. Press Trace 2 in PACER mode, or press either Trace 2 or Trace 3 in DEFIB or MONITOR
mode (for ALS models) or ON mode (for Plus or BLS models) to select the position.
5. To display the plethysmogram in the selected position, press SpO
2
. To remove the trace from
the display, press Off.
6. When you are finished, press Return twice to return to the main menu.
The third waveform disappears in DEFIB mode (for ALS models) or ON mode (for Plus or
BLS models) under the following conditions:
• When the CHARGE button is pressed
• When the ANALYZE button is pressed
• When the ENERGY SELECT button is pressed
• While synchronization is enabled
