An Oscillatory Positive Expiratory Pressure (OPEP) device helps open up clogged airways and expel mucus. OPEP devices are a subtype of Positive Expiratory Pressure (PEP) Devices. This device utilizes a flutter mechanism (not present in some PEP devices) to provide resistance and vibration during exhalation.
Mucus Clearance Devices relate to tools that help dislodge your airway of mucus. These devices are used in respiratory therapy procedures with the goal of easing the expulsion of mucus. Examples of Mucus Clearance Devices include PEP Devices, OPEP Devices and HFCWO.
COPD is a progressive disease with no known cure, treatment can help ease symptoms, prevent complications and its slow progression. At first, you may not even notice any signs except a bit of a cough and shortness of breath, but as the lungs become more damaged, the symptoms become worse and harder to ignore.
Emphysema is a respiratory disease where the millions of tiny air sacs in the lungs (alveoli) are damaged or ruptured. As these tiny air sacs are damaged they lose their natural elasticity and this causes the air sacs to close before you fully breathe out (exhale), as a result air gets trapped in the lungs.
