Pneumatic Design

The ZOLL Ventilator includes an oxygen valve and a compressor to provide the gas to the
output port. The system includes transducers for pressure measurements including input supply
pressure and barometric readings.
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.
The following image is a diagram of the ventilator's pneumatic design.
