HOW DOES IT WORK?
The Mylar reed is flared on the other end to increase the air mass within the device. This provides acoustic impedance. When the device is being used, the Mylar reed will oscillate at a frequency that matches the resonance frequency of pulmonary secretions (16-25Hz).
Thus, the viscosity of these secretions is reduced by mechanical vibrations resulting from the sound waves.
Additionally, these vibrations will also facilitate the action of the mucociliary escalator system, which will mobilize the loose and thin liquid jelly or mucus, to ensure optimal bronchial hygiene by easier and more effective expectoration.
INSTRUCTIONS
The following steps will ensure the correct use of the device:
-
First, perform a deep inhalation. Then, place lips around the mouthpiece. Exhale forcefully through the Lung Flute® as if trying to blow out a candle. After that, remove the mouthpiece and quickly inhale again. Now, put the mouthpiece back in the mouth, and blow gently through the Lung Flute.
-
Remove the mouthpiece again and wait 5 seconds, taking several normal breaths.
-
For best results, blow into the Lung Flute® for up to 20 sets of two blows per set. (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 throat and vigorous coughing may occur. Thinned mucus may collect at the back of the throat for several hours after the session, which is normal. A drink of water will wash away the mucus and prevent minor throat irritation.
