An airway clearance system is a device that helps people who have trouble clearing mucus from their lungs. Mucus is a sticky substance that traps dust, bacteria, and other particles that enter the airways. Normally, the lungs have tiny hairs called cilia that move the mucus up and out of the lungs. However, some people have conditions that make their mucus too thick or sticky, or damage their cilia. This can cause mucus to build up in the lungs and block the airways, leading to breathing problems and infections.
An airway clearance system can help these people by loosening and removing the mucus from their lungs. There are different types of airway clearance systems that use different methods, such as vibration, percussion, suction, or oscillation. One of the most common types is the chest vest, which uses high frequency chest wall oscillation (HFCWO).
A chest vest is a device that consists of an inflatable garment that wraps around the chest and a machine that pumps air into it. The machine delivers pulses of air to the garment, which creates gentle pressure waves that shake the chest wall. These waves travel through the lungs and break up the mucus, making it easier to cough or suction out.
A chest vest can help people who have conditions such as cystic fibrosis, bronchiectasis, chronic obstructive pulmonary disease (COPD), or neuromuscular disorders. It can improve their lung function, reduce their risk of infections, and enhance their quality of life. It can also be used at home or on the go, making it convenient and flexible.
