The following 3 screens are the Gas Machine Tests.
NB. This is just a set of instructions it is not an active test. Set the controls as instructed and carry out the manual test as instructed
making the necessary observations that all is working as correctly.
Having proved that the manual system works the ventilator can be tested at nominal settings of
TV 500 mL, 12 BPM, I:E 1:2.0 Set up the system as described Press the track wheel when ready
and set the Bag/Vent switch to Vent. Ensure that the Bag and Bellows are full. Observe the
displayed wave form and expired volume are consistent with the expected result. Other tests
can be carried out at the users discretion.
When this test is completed satisfactorily the system is ready for use.
The PEEP valve is tested during the Pre-Use test. If the valve is replaced or fitted during use the
Pre-Use test must be carried out to ensure continued accurate operation.
In later production systems an improved compliance compensation system has been
implemented. This has been improved in two ways:-
a. The pressure used in compensation is now averaged instead of using the last peak.
b. If a pressure limit is activated that peak is not fed into the average.
c. A rolling average of airway pressure is calculated that is used to monitor each delivered
breath. If the pressure rise is more than 25% above this rolling average an automatic limit will
be applied for that breath. This prevents abnormal high pressures being generated due to
patient movement or other artefacts. If a limit is activated this pressure will not be included in
the average.
