Lung flute. A lung flute is a medical device used to clear mucus from congested lungs with low-frequency sound waves. The device consists of a mouthpiece and a plastic reed which vibrates within a chamber to create sound waves in the chest cavity.
The lungs consist of two cone shaped spongy organs that contain alveoli and trap air for gas exchange. The lung is designed for gas exchange. Its prime function is to allow oxygen to move from the air into the venous blood and carbon dioxide to move out. Although the lung performs other functions, its primary responsibility is to exchange gas.
