Tests
Testing the outer hose:
1. Connect the breathing circuit as follows:
a. Connect the hose (1) to the inspiratory port (2).
b. Remove the coaxial test adapter (3) from the expiratory port (4).
c. Connect the elbow (5) to the hose (6).
d. Plug the hose (6) with the elbow connected on to the circuit plug (7).
e. Connect the hose (8) to the expiratory port (4).
2. Touch the Tests... button.
3. Touch the Leakage test button.
The determined leakage value is displayed as Leakage (mech. vent.). Note down
the value as the leakage of the expiratory hose.
Evaluation of the values determined for leakage:
Test of the inspira-
tory hose

Evaluation
The breathing circuit is intact.
Low leakage. Check whether the
breathing circuit is suitable for the
particular patient category.
Do not use the breathing circuit.
There is a risk of rebreathing.
Take account of the leakage when
setting the parameters for fresh gas
and ventilation.
Do not use the breathing circuit.
The leakage is possibly caused by
other components and not by the
breathing circuit. Repeat the test with
a different coaxial breathing circuit.
