18. Functional Testing
The functional test procedure is to be used in-conjunction with a checklist. The
checklist is used to record that each test has been passed. This checklist will be
become part of the service record of the ventilator. A template checklist (which
should be copied) is to be found in Appendix 2 of this manual on page 313.
Where information needs to be recorded the user will see symbol next to
the section.
18.1 Ventilator setup
The ventilator needs to be connected to air and oxygen. Fit the exhalation block
and silencer. A complete patient circuit needs to be connected with a N6647 test
lung at the ET manifold. Make sure that all the covers are in place. Connect the
ventilator to the mains power supply.
Prepare a calibration analyser with an ET tube connection.
18.1.1 Complete Power Fail Alarm Test.
Step 1 The ventilator has a complete power fail alarm. This alarm is activated when both
mains power and back-up battery power fail. This alarm is a high pitched,
continuous tone emitted by the ventilator in the event of complete power failure.
Turn ON the ventilator allow the start up screen to clear and wait for it to enter the
Ventilation OFF mode.
Calibrate Flow Sensor (for this calibration there is no need to occlude the flow
sensor).
Turn OFF the mains power by switching off the
supply at the wall socket or by removing the plug
from the socket.
This will trigger the mains power fail alarm.
