The Increase of Lung Capacity Using the Lung Master (Pulmonary Exerciser)

During the one-month using the Lung Master at their house, the participant will be using it at least one time every day, either in the morning or in the evening before going to sleep. During the session, the participants will sit upright and try to prolong the inhalation and exhalation breaths through the Lung Master device for at least three seconds. For each session, the participants will try to concentrate on 35-50 breaths in and breaths out which is about 2-5 minutes. Every session can involve using the Pulmonary Exerciser for a minimum of 5 minutes and a maximum of 20 minutes. After each session, participants will be asked to note how long they have used the device and when they have used it. Information from each session will be recorded on the Participant Device Log that will be provided.
