The AffloVest offers physicians and patients a medical device that helps clear your chest airways. The AffloVest gives patients a device that they can use at home or anywhere on a preventative type of therapy which could help to prevent mucus buildup and subsequent lung infections. In other words, if patients use this therapy as prescribed by their doctor, typically 1 to 2 times per day for just minutes a day at home, it may help prevent lung infections which lead to hospitalization and subsequent re-admissions.
