【Abstract】 Objective To investigate the diagnostic va lue of polysomnography (PSG) in sleep apnea syndrome (SAS) and the effect of sle ep apnea syndrome on sleep structure.Respiratory disorder oxygen saturation and cardiovescular system. Methods 230 patients were monitored with polysomnography. Results 108 patients were diagnosed as sleep apnea syndrome (SAS)(46.9%).12 2 w ere diagnosed as simple snore(SS).There was a significent difference between sle ep apnea syndrome and simple snore,in sleep structure,respiratory disorder,oxyge n saturation and cardiovescular system changes. Conclusions Polysomnography is a practical method in the diagno sis of sleep apnea syndrome,assessing the severity of the disease and method of therapy.更多还原
