Positive expiratory pressure (PEP) therapy for the treatment of cystic fibrosis (CF). This device is used to help clear phlegm from the lungs of a patient with CF. Air is pushed into the lungs as the patient exhales, which expands the airways. The pressure created in the lungs moves phlegm to the larger airways where it can be more easily cleared. CF is a hereditary disease affecting the lungs, sweat glands and digestive system. Both the lungs and pancreas produce abnormally thick mucus. The mucus in the lungs encourages bacterial growth, leading to severe respiratory infections. The mucus in the pancreas blocks the release of digestive enzymes, resulting in malabsorption.
