Inleiding

This guide provides step-by-step information on how to replace the Exhalation Valve Body for the Cardinal Health Vela Ventilator.

The exhalation valve is a critical component of any ventilator, designed to mitigate inward leakage of air contaminants during inhalation without inhibiting exhalation.

The Exhalation Valve Body may need to be removed for cleaning and sterilization, or to replace the exhalation valve diaphragm.

Viasys’ replacement guide for the Flow Sensor can be found on page 38 of the service manual attached.
