broken parts; loose assemblies; or disconnected wires, connectors, or tubing. Repair as
needed.
5.4 Preliminary ventilator setup
Set up the ventilator for the performance verification as follows:

Install a complete Puritan Bennett™ (or equivalent) ventilator breathing circuit. Verify
bacteria filters are installed.
NOTE:
A humidification device is not required for the performance verification or ventilation.
2.
Connect ventilator to an oxygen source.
5.5 Preliminary pneumatic test equipment setup
To set up your pneumatic test equipment for use in the performance verification, verify all
equipment is calibrated and
sufficient warm-up time has elapsed prior to measurement.
5.6 Performance verification procedures
To ensure systematic performance verification and logical fault diagnosis, perform these tests
in the order given. If you need to repeat a test, however, the current control settings are
completely defined at the beginning of each individual check.
