2.5.7 Mechanical

Overpressure

Valve

The Mechanical Overpressure Valve (MOPV) is a mechanical valve that operates
regardless of electrical power. It functions as a third level of redundancy to the
ventilator's pressure limit control functions, supplying pressure relief at approximately
110 cm H

O.

2.5.8 Free

Breathing Valve

The ventilator is programmed to supply a specified number of breaths per minute to
the patient. If, in between one of these programmed cycles, the patient needs a breath
(spontaneous), the free breathing valve permits the patient to inhale. The free breathing
valve is closed on mechanical inspiration.
