Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This purpose of this study is to determine whether nasal delivery of heated and humidified air for a period of 4 hours will improve the clearance of mucus from the lungs of patients with chronic obstructive pulmonary disease (COPD). Mucus clearance will be measured using a nuclear medicine imaging procedure called a mucociliary clearance scan. Humidified air (with added oxygen if needed) will be delivered from the Fisher and Paykel myAirvo2 heater/humidifier through an Optiflow nasal cannula.
