Performing the Pre-use Test

The pre-use test is used for detecting the type and characteristics of the patient circuit
that is connected to the Vivo 45 LS. 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.
NOTE
If the pre-use test has not been performed, the Vivo 45 LS will operate with default
patient circuit compensation.
