4.2.4 PATIENT CIRCUIT TEST

The test measures the compliance and

resistance of the patient breathing system.

The patient circuit resistance is automatically

measured to determine if the ventilator

maintains the specified accuracy with the

connected breathing circuit.

Connect the complete breathing system

to be used on the patient. If an active

humidifier is used, it must be filled with

water.

VX-155a_XX

Important: When blocking the end of

the complete breathing system, make

sure there is no leakage. Leakage will

affect the circuit compliance

compensation calculation.

Block the end of the complete breathing

system and follow the on-screen

instructions. The circuit compliance and

resistance are automatically measured.

Go to Compensate for Circuit compliance

(see page 46).

VX-155b_XX

Unblock the end of the complete

breathing system and follow the on-screen

instructions.
