What is the purpose of a percussion vest?

The purpose of a percussion vest is primarily to aid in clearing the airway of mucus. This device works by using vibrations and percussion to help loosen and mobilize mucus that may be trapped in the lungs. By shaking the chest and creating waves in the lung tissue, the vest promotes the movement of mucus toward the larger airways, making it easier for the individual to cough it up. This is particularly beneficial for individuals with respiratory conditions, such as cystic fibrosis or chronic obstructive pulmonary disease (COPD), where mucus accumulation can lead to blockages and increased risk of infection.

While the options focusing on improving lung function and measuring or providing supplemental oxygen are related to respiratory health, they do not specifically address the function of the percussion vest. The vest does not directly improve lung function in a general sense, nor does it serve as a tool for measuring oxygen levels or delivering supplemental oxygen. Its primary role lies in facilitating mucus clearance, which correlates with overall lung health and function indirectly through improved airway clearance.
