The Lung Flute - An Acoustic Device for Airway Clearance
Introduction[edit | edit source]
It is a handheld device that uses sound waves to mobilize and clear secretions.
Method of Use[edit | edit source]
Mechanism of Action[edit | edit source]
The patient inhales a little deeper than normal, places his/her lips completely around the mouthpiece, and blows out through the Lung Flute as if trying to blow out a candle. When the patient has finished exhaling, he/she will remove the mouthpiece from his/her mouth, quickly inhale again, put the mouthpiece back in his/her mouth, and blow gently through the Lung Flute.
The patient then removes the mouthpiece again and waits 5 seconds, taking several normal breaths.
In order to achieve the best results, the patient should aim for blowing into the Lung Flute for up to 20 sets of two blows per set. As with any therapy, patients may need to begin slowly and build up the number of repetitions over time.
Approximately 5 minutes after the session has ended, mucus will have collected at the back of the patient's throat and he/she can start to cough vigorously. The patient may notice thinned mucus collecting at the back of his/her throat for several hours after the session. This is normal. A drink of water will wash away the mucus and can prevent minor throat irritation.
