Objective,2,To analyze the distribution and characteristics of TCM syndromes in patients with obstructive sleep apnea （OSA）.,Methods,2,60 patients， who were diagnosed with OSA during hospitalization from January 2020 to January 2022 in the General Department of Beijing Hospital of Traditional Chinese Medicine affiliated to the Capital Medical University， were collected. The gender，age， TCM syndromes， apnea-hypopnea index （AHI），minimum blood oxygen saturation at night （SaO,2,）， and complicated underlying diseases were summarized.,Results,2,Among 60 OSA patients， 33 cases （55.00%） were characterized by mutual obstruction of phlegm and stasis， 13 cases （21.67%） were characterized by dampness and heat obstruction in the middle jiao， 8 cases （13.33%） were characterized by lung and spleen qi deficiency， and 6 cases （10.00%） were characterized by lung and kidney Yang deficiency. Mild OSA was more likely to occur in lung and kidney Yang deficiency than other syndromes（,P,<, 0.05）. Severe nocturnal hypoxemia was more likely to occur in the phlegm-stasis syndrome group than in the other syndrome groups （,P,<,0.05）. 65.00% patients were complicated with hypertension， and the syndrome of mutual obstruction of phlegm and stasis together with hypertension was more than that of other syndromes（,P,<,0.05）.,Conclusion,2,Among the OSA patients，the syndrome of mutual obstruction of phlegm and blood stasis and dampness and heat obstruction in the middle jiao are the most common. Most patients with phlegm and blood stasis syndrome suffer from moderate to severe OSA，more severe hypoxemia at night，and higher risk of hypertension. Patients with lung and kidney Yang deficiency syndrome are more likely to develop mild OSA.
