Effect of Nasal CPAP on Cardiopulmonary Exercise Testing in Patients With Overlap Syndrome

Completed

Conditions studied: Obstructive Sleep Apnea, Chronic Obstructive Pulmonary Disease

In brief

Nasal CPAP will improve cardiopulmonary exercise test (CPET) performance in patients with overlap syndrome(COPD and OSA). Nasal CPAP is proven to improve cardiopulmonary exercise testing in patients with OSA. The investigators hypothesis is that patients with overlap syndrome will have a greater improvement in their cardiopulmonary exercise testing besides a possible improvement in their lung function test and airway resistance.
