Performing a Pre-Use Test

The pre-use test is used for detecting the characteristics of the patient circuit that is con-
nected to the ventilator. The resistance and compliance of the patient circuit are measured
and calculated. This will be used to compensate for pressure drop in the patient circuit and
the compliance of the patient circuit.
The patient shall not be connected during the pre-use test.
