Service Manual

The Pulse Search indicator illu-
minates after successful mea-
surements occur.
•
Check the status of the patient.
•
Perfusion may be too low for the monitoring system to track the pulse.
Test the monitoring system on another patient. Change the sensor site
and/or try another type of Nellcor™ sensor.
•
Interference may be preventing the monitoring system from tracking
the pulse. Verify the sensor is securely applied and replace it if neces-
sary. Change the sensor site. Use a type of sensor that tolerates more
patient movement; for example, an Nellcor™ adhesive sensor. Electro-
magnetic interference may be preventing the monitoring system from
tracking the pulse. Remove the source of interference and/or try to
stabilize the environment.
•
The sensor may be too tight, there may be excessive ambient light, or
the sensor may be on an extremity with a blood pressure cuff, arterial
catheter, or intravascular line. Reposition the sensor as necessary.
Alarms only briefly actuate.
•
Check patient trend data.
•
Examine the patient.
•
Determine if Alarm Audio Off is enabled. If so, an alarm will sound
every three (3) minutes.
•
Determine if the SPD alarm is active and alarming.
•
Check the speaker. Reference
Table 11-6.
