Overlap syndrome is a term which specifies the existence of both chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA) in the same patient. The prevalence of OSA in COPD patients equals its prevalence in the general population. Overlap patients have a greater degree of hypoxemia and hypercapnea than COPD patients matched for stage. They also have a greater prevalence of pulmonary hypertension and right heart failure, and suffer higher morbidity. Due to these consequences of the overlap syndrome, it is recommended to actively search for its existence in COPD patients, and to treat it with continuous positive airway pressure (CPAP) concurrently with oxygen and optimal pharmacological treatment of COPD.

UI	MeSH Term	Description	Entries
D006976	Hypertension, Pulmonary	Increased VASCULAR RESISTANCE in the PULMONARY CIRCULATION, usually secondary to HEART DISEASES or LUNG DISEASES.	Pulmonary Hypertension
D009017	Morbidity	The proportion of patients with a particular disease during a given year per given unit of population.	Morbidities
D006333	Heart Failure	A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.

D015995	Prevalence	The total number of cases of a given disease in a specified population at a designated time.

D045422	Continuous Positive Airway Pressure	A technique of respiratory therapy, in either spontaneously breathing or mechanically ventilated patients, in which airway pressure is maintained above atmospheric pressure throughout the respiratory cycle by pressurization of the ventilatory circuit.

D020181	Sleep Apnea, Obstructive	A disorder characterized by recurrent apneas during sleep despite persistent respiratory efforts. It is due to upper airway obstruction. The respiratory pauses may induce HYPERCAPNIA or HYPOXIA. Cardiac arrhythmias and elevation of systemic and pulmonary arterial pressures may occur. Frequent partial arousals occur throughout sleep, resulting in relative SLEEP DEPRIVATION and daytime tiredness. Associated conditions include OBESITY; ACROMEGALY; MYXEDEMA; micrognathia; MYOTONIC DYSTROPHY; adenotonsilar dystrophy; and NEUROMUSCULAR DISEASES.
