3 Alarms and Troubleshooting
Warning
Setting Alarm limits to extreme values can cause the ventilator alarms to malfunction.
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.
The alarms or faults generated by your Puritan Bennett™ 560 Ventilator are classified into
two categories:
•
Ventilation (or utilisation) alarms
•
Technical faults
Some of the ventilator alarms are adjustable, depending on ventilation modes. Automatic, non-adjustable
alarms also exist to create a safety net for safer patient ventilation.
Alarms indicate events likely to affect the ventilation in the short term and necessitate rapid intervention (refer
to section
3.8, “Troubleshooting” ).
Technical faults do not directly affect machine operation. Therefore, the user is not alerted to technical faults.
Only authorised and trained technicians may consult the maintenance menu (refer to the Puritan Bennett™
560 Service Manual).
Note:
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.
Default alarm setting preferences should be entered prior to using the ventilator.
