Official title
Peak Inspiratory Flow (PIF) and Dry Powder Inhaler (DPI) Performance in Chronic Obstructive Pulmonary Disease (COPD)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of the study is to determine whether PIF is clinically important when using the Ellipta DPI device. In addition, the study will validate the best/most clinically appropriate way to perform a PIF maneuver, to determine the testing capabilities of the preferred PIF maneuver and to relate this PIF measurement to meaningful clinical outcomes in COPD patients
