Pneumatic Design - ZOLL Z Vent Operator's Manual

In the event that the ventilator needs to be shutdown, turn the POWER switch to the OFF ("O")
position. If this fails to work or puts the patient or user at possible risk, disconnect the device
from the external power source.

Pneumatic Design

The ventilator includes an oxygen valve and a compressor to provide the appropriate gas
mixture for the patient. The system includes transducers for pressure measurements including
O input supply and barometric pressure.

The Wye circuit is part of the ventilator's pneumatic system. The inspiratory side of the wye
circuit provides gas to the patient. The expiratory side exhausts directly to atmosphere without
returning to the ventilator. The ventilator pneumatically controls the exhalation valve and a
transducer within the ventilator measures the airway pressure.
