Study Summary
The purpose of study is to evaluate the physiologic effects of pulmonary tissue/structural changes associated with COPD and upper airway inflammation on upper airway collapsibility. Upper airway collapsibility is closely associated with development of obstructive sleep apnea (OSA), which is a common disease characterized by repetitive collapse of upper airway during sleep, leading to hypoxemia and arousal. OSA has important neurocognitive and cardiovascular consequences, especially in patients with COPD. Participants in this research study will undergo two overnight sleep studies (PSGs), pulmonary function test, and CT scan of the upper airway and chest. The first sleep study will evaluate the sleep breathing disorder and the second sleep study will measure the upper airway collapsibility, called critical closing pressure (Pcrit). Pcrit is measured by a modified continuous positive airway pressure (CPAP) machine which can provide a wide range of pressures between 20 and -20 cmH2O in order to modify upper airway pressure.
