Instructions for Using an Oscillating Positive Expiratory Pressure (OPEP) Device
Your child’s healthcare team has prescribed an OPEP device to help clear mucus from the lungs. The OPEP uses vibration and positive pressure to help thin out and move the mucus. It is important to follow the directions closely when using this device to make it as effective as possible.
