For patients experiencing high mucus production from conditions such as CF, which airway clearance device is recommended?

High-frequency chest wall oscillation, often referred to as vest therapy, is particularly effective for patients with conditions like cystic fibrosis (CF) that lead to high mucus production. This device uses rapid oscillations delivered to the chest via an inflatable vest, which helps to loosen and mobilize thick mucus from the airway passages. By vibrating the chest walls, it encourages mucus clearance, making it easier for patients to expectorate.

The use of this technique is beneficial for individuals with CF, as they commonly struggle with the management of thick and sticky mucus. The oscillatory effects of the vest therapy help to prevent mucus buildup and potential lung infections by facilitating the movement of secretions toward the larger airways, where they can be more easily coughed out.

Other airway clearance devices exist, but they may not provide the same level of mucus mobilization effectiveness found with high-frequency chest wall oscillation. For example, continuous positive airway pressure (CPAP) is designed primarily to keep the airways open during sleep but does not target mucus clearance directly. Similarly, positive airway pressure adjuncts can aid in keeping airways open but aren’t primarily focused on mucus clearance. Mechanical insufflation-exsufflation (MIE) has its role in assisting with cough
