O.V.T
The patient circuit must be tested each time it is connected, so if you are
reconnecting a patient circuit or using a new one, you must perform the
Operational Verification Test (O.V.T.). This test, which takes less than one minute,
checks the integrity of the breathing circuit and audible alarm functionality.
Two plastic caps for covering the ends of the patient circuit are required for the
O.V.T. They are included with all patient circuits offered by Versamed.
To perform an O.V.T.:
1. Rotate the Control Knob until the O.V.T. option is selected in bright blue.
2. Press the Control Knob until you hear a click. The O.V.T. Instructions pop up
