Pre-operation Procedures

4.1.8   Leak Test / Compliance Value Calculation

Leak Test

1.  Select LEAK TEST through the Menu in Standby Mode.

2.  Check for a leak using an occluded breathing system.

3.  Disconnect gas sampling modules connected to patient 

monitoring equipment during this test.

This procedure checks the breathing system for pressure 

leakage, and calculates and displays 

Leak Level

 and 

Breathing System Compliance.

1.  Occlude the breathing circuit at the patient Y-piece

2.  Ensure that the bellows are fully inflated.

3.  Turn the gas delivery switch (1) off. 

This will stop all gas flows (including oxygen basal flow) 

and will also turn the AVS off. 

Then switch the AV-S on (2)  - at the ventilator (do not use 

the gas delivery switch).

4.  Press the menu switch (3). 

Select LEAK TEST from the main menu. 

Select <START/STOP LEAK TEST> to start the leak test. 

The ventilator will now drive gas into the absorber until 

a pressure of 30 cmH2O is obtained, and then hold that 

pressure for approximately 25 seconds before releasing 

the pressure and completing the test.

5.  The menu will display the leak test results:

a)  Leak Level: Leak rate is displayed

 NOTE

During the test, any pressure drop discovered once the 30 

cmH2O level is reached will be displayed as a possible leak 

by the ventilator self-test.

This includes pressure drop due to the relaxation of 

any elastic components in the breathing system (e.g. a 

breathing bag)

b)  (b) BSys Comp: Compliance 

BSys Comp is the compliance of the breathing system 

and is the value that will be used in providing the 

default compliance compensation for volume delivery.

 NOTE

a)  Default value is 7.0 cmH2O.

b)  Upper limit is 18 cmH2O (sufficient for normal 

breathing system capacities).

c)  The ventilator will continue to operate, irrespective of 

any detected leak.

d)  It is the responsibility of the user to determine if the 

detected leak is significant.
