Objective To analyze the clinical characteristics of patients with COPD and OSA. Methods 100 patients with chronic obstructive pulmonary disease and obstructive sleep apnea (observation group) and 100 patients with chronic obstructive pulmonary disease (control group) admitted to our hospital from April 1, 2022 to March 31, 2024 were selected as the research subjects. The respiratory data (SLT, RDI, LAT, AHI), blood oxygen distribution (meanSaO2, miniSaO2, TS90%), lung function (FEV1%, FEV1/FVC) and arterial blood gas indexes (pH, PO2, PCO2) of different patients were monitored by portable sleep monitoring. Results Compared with the control group, the observation group had a shorter sleep latency, more frequent respiratory disorders, higher LAT values, higher AHI values, significantly lower meanSaO2 and miniSaO2 values, higher TS90% values, lower FEV1% and FEV1/FVC values, lower PO2 and pH values, and higher PCO2, and the above comparisons were statistically significant (P < 0.05). Conclusion Compared with patients with simple COPD, patients with COPD and OSA have more prominent sleep quality problems, more severe hypoxemia symptoms, and poorer lung function.
