Expiratory valves Expiratory valves

Controlling the expiratory gas flow. A key aspect of ventilation therapy

The main task of the expiratory valve set is to control the respiratory phases and the positive end-expiratory pressure (PEEP). 

It is also designed to prevent internal ventilator components from coming into contact with the patient’s exhaled gas.

Our single-use and autoclavable expiratory valve sets consist of three different components: housing, membrane, and locking ring (Excluding expiratory valve for HAMILTON-G5/S1 and GALILEOA​). They are specially developed for use with our ventilators.
