3.3 Pre-use Testing 6700 Ventilator

The patient airway flow sensor head must be in the patient circuit in order to carry out
compliance compensation.

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.

The option to run a pre-use test is built into the start-up screen. It is initiated by pressing the

‘

?

’

key or skipped by pressing the ‘alarm reset’ key. If the compliance compensation test is

skipped the message “compliance cancelled, no compensation” is displayed.

Follow the instructions given on screen and the ventilator will perform a Pre-use test and a leak
test.

On satisfactory completion of the compliance compensation test “compliance set ok” is
displayed.

If any part of either the leak or compliance test is failed, the user will be alerted by an on screen
message as to which test has been failed and instructed to press

‘

?

’

to retry. At this point the

user can elect to skip the test or to retry.

During Pre-use Test if fresh gas is set to greater then basal flow then compliance will fail and the
‘fresh gas too high’ message will be displayed

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.
