oscillatory positive expiratory pressure (OPEP)

Oscillatory positive expiratory pressure (OPEP) is a technique used to help clear mucus from the lungs. It involves breathing out through a device that creates gentle vibrations and resistance, which helps loosen mucus in the airways. This process improves airflow and makes it easier to cough up the mucus, aiding in lung hygiene. OPEP is often used by individuals with lung conditions like COPD or cystic fibrosis to prevent infections and improve breathing. It is generally safe, non-invasive, and can be performed at home with proper guidance.
