Puritan Bennett 560 Ventilator User's Manual - Covidien

E Alarms Tests
Before connecting the ventilator to the patient, perform the following tests to ensure the ventilator‘s alarms
are working properly.
Warning
Do not perform ventilator alarm tests while the patient is connected to the ventilator. Provide
the patient with an alternate means of ventilation before conducting these tests.
If the ventilator fails any alarm test or if you cannot complete these tests, see the
Troubleshooting section (refer to chapter 3, “Alarms and Troubleshooting”) of this manual or
call your equipment supplier or Covidien (refer to section 8.3, “Service Assistance”).
The setting of the Min PIP alarm must be adjusted for the patient, but must also be set high
enough to allow the PATIENT DISCONNECTION alarm to trigger properly. Perform the Low
Pressure Test (refer to section E.1, “Low Pressure Test”) to ensure the Min PIP alarm is properly
set.
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.
Most of these tests require that an approved patient circuit be connected to the ventilator. Ensure that
your patient circuit is properly connected prior to performing these tests.
