Chronic obstructive pulmonary disease (COPD), which includes chronic bronchitis and emphysema, is one of the most common causes of death in the US. Often the result of smoking, it’s characterized by a restriction of the airways. Four years ago, a device known as the Lung Flute received FDA approval as a treatment for COPD. Now, a study conducted by the University of Buffalo has concluded that the hand-held device is indeed effective at helping patients breath more freely.
Manufactured by Buffalo, New York-based Medical Acoustics, the Lung Flute requires users to simply blow into it. Doing so causes an integrated reed to vibrate, producing low-frequency sound waves which travel down into the patients’ lungs. There, the waves break up the mucus, allowing it to subsequently be cleared when the user forcefully exhales.
