The Vest

The Vest™ system consists of an inflatable vest connected
by tubes to an air-pulse generator. The generator rapidly
inflates and deflates the vest, compressing and releasing
the chest wall up to 25 times per second. This technology
is called high-frequency chest wall oscillation (HFCWO).
The rapid chest movement mimics “mini-coughs”

A session with The Vest system takes approximately 
15-20 minutes).  The patient does not have to be repositioned 
during therapy–  Therapy can be administered to a patient 
in any position, even while sitting in a bedside chair. 

Vests are disposable- single patient-use units.
