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 medical device uses high-frequency vibrations to help loosen secretions in the lungs, making it easier for individuals with respiratory conditions, such as cystic fibrosis or chronic obstructive pulmonary disease (COPD), to expel mucus. By facilitating the movement of mucus, the percussion vest plays a crucial role in maintaining airway clearance, which is essential for lung health and functionality.

While improving lung function might be a secondary benefit, it is not the primary design or purpose of the vest. Devices that measure oxygen levels or provide supplemental oxygen serve very different functions—monitoring and enhancing oxygenation rather than focusing on mucus clearance. Thus, the function of a percussion vest is specifically targeted at aiding in airway clearance, confirming the accuracy of the selected answer.
