Obstructive Sleep Apnea in Patients with Chronic Obstructive Pulmonary Disease
Pantaree Aswanetmane, Chok Limsuwat
Obstructive sleep apnea (OSA) and chronic obstructive pulmonary disease (COPD) are common disorders in clinical practice and are associated with significant cardiovascular morbidity. The simultaneous occurrence of OSA and COPD happens frequently and is referred to as an overlap syndrome. These patients often have very poor quality sleep and more nocturnal hypoxemia. This combination may increase the severity of metabolic complications and cardiovascular disease, and these patients have increased mortality when compared to patients with either COPD or OSA alone. The treatment of overlap syndrome should focus on both coexisting diseases and includes continuous positive airway pressure, oxygen supplementation, and medications for chronic lung disease.
