ZOLL R Series Monitor Defibrillator Rev D - Manual (Page 13)

Monitoring a Patient
9650-0901-01 Rev. D R Series Pulse Oximetry (SpO
2
) 11
4. If the pulse indicator shows a weak signal, check the oximeter sensor or apply it to a more
appropriate site.
If necessary, enable SpO
2
alarms and adjust the alarm limits. Refer to “Setting SpO2
Alarms” on page 13.
Note: If ECG leads are not attached to the patient, the unit uses SpO
2
pulse measurements for
displaying the heart rate (HR) in the ECG area. In this case, the heartbeat indicator
does not flash.
Note: If the unit displays the message SPO2 COMM ERROR shortly after powering on, the
SpO
2
monitoring subsystem has failed. Contact ZOLL Technical Service.
Adjustable SpO
2
Settings
The pulse oximeter includes several settings which you can adjust when the unit is in clinical
mode:
• Sensitivity level
• Measurement averaging period
• Plethysmogram display
• SpO
2
alarm state and limits (SpO
2
and pulse rate)
Any change you make to one of these settings remains in effect until changed again or until the
unit is turned off for at least 10 seconds. When restarted, the unit reinstates its configured
default settings, which can differ from the factory defaults. (For the factory default values, refer
to “Default Settings for the SpO
2
Option” on page 14.)
To access the SpO
2
monitoring functions:
1. Turn the Mode Selector to the following:
• MONITOR for ALS models.
• ON for Plus or BLS models. Press the Manual Mode softkey, and then the Confirm
softkey to enter the Manual mode of operation.
2. Press the Param softkey.
Softkey labels for the SpO
2
functions appear: Sens (used to adjust the SpO
2
sensitivity), and
Average (used to adjust the SpO
2
averaging period). Follow instructions in the two
subsequent sections.
Setting the SpO
2
Sensitivity
The Sens softkey allows you to select either Normal or High sensitivity for SpO
2
monitoring.
Normal sensitivity is recommended for most patients.
Under very low perfusion conditions, such as severe hypotension or shock, high sensitivity
might provide more accurate measurements.
Note: With high sensitivity, SpO
2
measurements are more easily contaminated by artifact;
carefully and continuously observe the patient.
To set the SpO
2
sensitivity level:
1. Press the Sens softkey.
The Normal and High softkeys appear.
2. Press the softkey for the preferred SpO
2
sensitivity, then press the Return softkey.
