Application Description:  


The first breathing exercise app of its kind for patients with COPD and Asthma. This app coaches users to practice a phonetic breathing exercise that promotes deep breathing and well-being.

Full description:

Progressively hyperextended alveoli leading to the destruction of lung parenchyma is the basic pathophysiology for development of emphysema and COPD. Increase the length of exhale deeper and slower and make it as smooth as possible are fundamental to ensure the alveoli not going overextend or to collapse or collapse with positive end expiration pressure being maintained at 0cm H2O pressure which is equal to the atmosphere pressure. The common obstacles are related to inconsistency on the instructions on how to be able to breathe effectively. Exheale coaching program strategically selects words that promote longer exhalation with loose lip closure. For example, the word "woof" is used in one of the exercises. The instructions ask the participants to pay close attention to the inhale to exhale timer. Inhale with open mouth while silently saying "woo" in one to two second. Then, exhale with lips loosely closed while making the second part of the word "f" as long as you can. The emphasis is on the resistive phonation during the exhalation and prolongation of the exhalation as the exercise progressively getting harder.
