3.8 Troubleshooting
Warning
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 and avoid the possibility of physical injury to personnel or damage
to the ventilator, only personnel authorised and qualified by Covidien should attempt to service
or make authorised modifications to the Puritan Bennett™ 560 Ventilator.
3.8.1 Alarms
Table 3-2 offers a guide to the most likely ventilator alarms, possible reasons for the alarms, and
corrective actions.
Warning
Do not attempt to open, repair or otherwise service the ventilator yourself. Doing so might
endanger the patient, damage the ventilator, and/or void your warranty. Only personnel
authorised and qualified by Covidien should repair, open or service the ventilator.
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.
Note:
The ventilator screen must be unlocked before setting and parameters can be changed.
Many of the functions of the ventilator are not accessible when the Locking key is enabled. For
additional assistance contact your Clinician or equipment representative.
