High frequency chest wall oscillation(HFCWO) for aiway clearance
Why Need the Coughvest Airway Clearance System
Many people with chronic respiratory conditions struggle each day to adequately remove secretions from their lungs. This can be due to the volume or thickness of secretions, muscle weakness leading to an ineffective cough or even the reliance on others to assist with airway clearance. Retained secretions may lead to increased rates of respiratory infection, hospitalisation and reduced lung function.
In order to assist you in improving mucus clearance , Konted developed the Coughvest Airway Clearance System to deliver High Frequency Chest Wall Oscillation (HFCWO).
What HFCWO is
High frequency chest wall oscillation (HFCWO) draws its effectiveness from the science of fluid mechanics,
the study of fluids and the forces which act upon them. Because mucus is a viscous fluid, it tends to resist movement. But sufficient and sustained airflow creates what physicists call “shear force,” which can cause even high-viscosity fluids to shift and flow.
How the CoughVest Airway Clearance Work?
The Coughvest Airway Clearance System consists of an inflatable vest connected by tubes to an air-pulse generator. The generator rapidly inflates and deflates the coughvest, compressing and releasing the coughvest wall up to 25times per second. This technology is called High Frequency Chest Wall Oscillation (HFCWO).
The rapid chest movement minics”mini-cough” that dislodge and thin the mucus, moving it along to the central airways. The coughvest therapy treats all lobes of the lungs simultaneously and it technique indepent. It can be beneficial to patients across the continuum of care, including acute and post-acute facilities, as well as at home
