3.8 Troubleshooting
3.8.1 Alarms
Table 3-2 offers a guide to the most likely ventilator alarms, possible reasons for the alarms, and
corrective actions.
Caution
•
This manual tells you how to respond to ventilator alarms, but it does NOT tell you how to respond to the
patient.
•
To ensure proper servicing of the ventilator and reduce the possibility of physical injury, only qualified
personnel should attempt to service the Puritan Bennett 540™ Ventilator.
WARNING
When an alarm condition is triggered, or there is evidence of a patient-ventilator fault or problem,
examine the patient first before examining the ventilator.
WARNING
Except for replacing the internal battery and cleaning the device, do not try to repair or otherwise service
the ventilator yourself, or modify the ventilator, its components, or accessories. Doing so might endanger
the patient, cause damage to the ventilator, and/or void your warranty. Only qualified service personnel
should attempt repair of the ventilator.
