Registry for Chronic Obstructive Pulmonary Disease With Sleep Apnea Hypopnea Syndrome in China
Registry for Chronic Obstructive Pulmonary Disease With Sleep Apnea Hypopnea Syndrome in China
COPD and sleep apnea dyspnea syndrome represent two of the most common chronic lung diseases.
 It is reported that the prevalence of COPD with sleep apnea dyspnea syndrome is also very
 high. COPD and sleep apnea may have pathological or genetics interactions so that patients
 having both disorders tend to have worse outcomes than either condition alone. Data
 reflecting the prevalence, disease course and outcome of overlap syndrome is very limited in
 China. Therefore, the aim of the study is to describe the prevalence, treatment and outcome
 in Chinese patients and exploring the underlying interaction mechanism.
Inclusion Criteria:

 -  COPD patients with informed consent

 Exclusion Criteria:

 -  pregnant patients, patients with serious respiratory diseases other than COPD,
 patients with limited life expectancy, patients that can't coordinate well
