Study Arms:
- Vitabreath Device (Type: EXPERIMENTAL): 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.
- Pursed Lip Breathing (Type: ACTIVE_COMPARATOR): 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.

Based on this trial design, predict the completion outcome and termination type (if applicable).
