Composed of a non-stretchable inflatable jacket vest/chest strap fitted after expansion and an adjustale pulse gas generator (i.e. main engine);
Connected by a tube, the main engine inflates/deflates at high speeds, and the vest creates high-frequency, low-amplitude movements in the patient's chest. It evenly acts on the entire chest wall and spreads through the chest wall to the bronchus at all levels of the lung, repeatedly producing cough-like shear forces that release sputum and promote sputum to move to the atmospheric tract.

Benefits of High-Frequency Chest Wall Oscillation :

• Improved Breathing: By reducing mucus buildup, it helps keep airways clear, reducing infections and hospitalizations.
• Ease of Use: It is non-invasive and often self-administered, allowing patients to perform airway clearance independently at home.
• Comfort: Most patients find the vibrating vest more comfortable than manual percussion.
