Brief Summary

Dyspnea is the most common symptom limiting the ability of COPD patients to perform activities of daily living. Although there has been research involving the benefit of providing Non Invasive Ventilation (NIV) during exercise to increase tolerance overall, there is little research specifically looking at shortening dyspnea recovery times associated with exercise. We hypothesize that providing intermittent non-invasive positive pressure therapy (a form of NIV or PAP) with a handheld device to COPD patients immediately after exertion can relieve their dyspnea, and consequently allow them to be more active. In this study, we are comparing the distance walked as measured by a modified 6-Minute Walk Test (6MWT) of 20 COPD patients using VitaBreath (NIV) device versus Pursed Lip Breathing.

• Allocation Method: RANDOMIZED
• Intervention Model: CROSSOVER
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

Vitabreath Device

The Philips Respironics investigational device VitaBreath is a handheld, battery powered, intermittent positive airway pressure device that is non-invasive, and provides positive airway pressure (PAP) of 18 cm water (H2O) during inspiration and 8 cm H2O on expiration, thus creating 10 cm H2O of pressure support. Pressure support is defined as the difference between inhalation pressure and exhalation pressure. The study device is intended as an adjunct therapy to relieve shortness of breath in COPD patients who experience exertion-related dyspnea to allow them to be more active. The air is delivered to the patient via a mouthpiece on the device.

Group Type: EXPERIMENTAL

Vitabreath Device

Intervention Type: DEVICE

The VitaBreath device is designed for non-continuous use only and typical device use is expected to be for 2-3 minutes. The device should only be operated for less than 10 minutes at a time. After such time, the device should be turned off for at least 30 minutes

Pursed Lip Breathing

Pursed lip breathing is a commonly used technique by COPD patients. That involves exhaling through tightly pressed lips and inhaling through the nose with the mouth closed.

Group Type: ACTIVE_COMPARATOR

Pursed Lip Breathing

Intervention Type: OTHER

Pursed lip breathing (PLB) is the standard of care and will be used as the control condition comparator.

Exclusion Criteria

• Subjects who are acutely ill, medically complicated or who are medically unstable as determined by the investigator.
• Suffering from COPD exacerbation at time of enrollment or 60 days prior
