What condition would require the use of Positive Expiratory Pressure (PEP) devices?

The use of Positive Expiratory Pressure (PEP) devices is particularly beneficial for individuals with cystic fibrosis. This condition leads to thick, sticky mucus production in the lungs, making it difficult for patients to clear secretions effectively. PEP devices help by providing a controlled resistance during expiration, which creates a pressure that helps to open the airways and allows trapped mucus to be mobilized and expelled more effectively.

In cystic fibrosis, the main therapeutic goal is to improve airway clearance and prevent infections, both of which are achievable with PEP therapy. By enhancing the patients' ability to remove mucus, PEP devices contribute significantly to the management of respiratory symptoms and overall lung health in these individuals.
