Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This is an early phase clinical trial to test the efficacy of elevating lung volume with positive expiratory pressure (CPAP) as a controller therapy for asthma in patients with a BMI ≥ 30 kg/m2. There will be two phases to this trial. Phase I: In the first phase we will determine the optimal duration of CPAP that is effective as a controller therapy in asthma. Up to 9 participants will complete this this phase. Phase II: The 2nd phase will be a randomized double-blinded controlled trial of Sham CPAP versus CPAP 10 (using the duration of CPAP determined in phase I) as a controller therapy for asthma, and also to determine the effect o airway reactivity in healthy people with a BMI 30 kg/m2 and above. Twenty people with asthma and twenty controls will complete this phase.
