Effect of CPAP on 6-Minute Walk Test Outcomes in Patients With ECAC
The purpose of this protocol is to perform a prospective, randomized, double-blinded, pacebo-controlled clinical trial to determine the influence of a non-invasive positive pressure ventilation device on exercise capacity and symptoms in adult patients with ECAC. Primary outcome will include the total distance traversed by the study subject during a standard 6-minute walk test, and secondary outcomes will include peak flow measurement and symptom reporting before and after the exercise testing. The study will focus on the use of continuous positive airway pressure (CPAP) device. CPAP is FDA-approved for the treatment of various medical conditions, including obstructive sleep apnea and heart failure, but is not FDA-approved for the treatment of ECAC. The study will enroll 32 ambulatory study subjects with confirmed ECAC at the BIDMC, and each study subject will be monitored for up to 3 months.
