Study Details

Brief summary:

Investigators are studying how a device called The Lung Master device can help people breathe better. The investigational device increases the amount of air our lungs can hold, which is important for overall lung health. The Lung Master is not approved by the FDA.

The study has two visits approximately one month apart. In the first visit participants will take a spirometry test, particularly forced vital capacity (FVC), to measure volume change in the lungs. Participants will take the investigational device home to use daily, either in the morning or evening. Use will be recorded in a diary. After one month, participants will return for another spirometry test. Each study visit will take about one to two hours to complete.

Interventions and Outcome Measures

Arms

experimental: Lung Function in Young and Older Adults

Lung functions will be assess for two groups: young and older adults. The age range of 19 to 35 is categorized as young adulthood. This age range was selected because the lungs mature around 19-25 years old. The age range above 65 is designated as late adulthood, where lung function gradually declines.

Interventions

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.

Primary outcome measure

  • Inspiratory Capacity [ Time Frame: baseline and after one month of device use ]
  • Tidal Volume [ Time Frame: baseline and after one month of device use ]
