The Increase of Lung Capacity Using the Lung Master (Pulmonary Exerciser)
What this study is about
Investigators are studying how a device called The Lung Master device can help people breathe better. The experimental 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.
View original scientific description
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
DEVICE
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 measures
Inspiratory Capacity
Time frame: baseline and after one month of device use
After reaching the end of a normal, quiet expiration, the maximum volume of air that can be inspired will be measured.
Tidal Volume
Time frame: baseline and after one month of device use
The amount of air that moves in or out of the lungs with each respiratory cycle will be measured.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
