Polysomnography analyses and treatment of obstructive sleep apnea-hypopnea syndrome in senile patients

Objective To analyze the characteristics of polysomnography and treatment in senile patients with obstructive sleep apnea-hypopnea syndrome.Method 32-guide polysomnography was performed on 87 senile patients and 296 middle-juvenile patients with obstructive sleep apnea-hypopnea syndrome,and the results were analyzed by Polysmith.Also the 87 senile patients were treated with continuous positive airway pressure(CPAP)and an oral appliance(OA).Results The AHI was (25.97±18.23)/h in the senile patients and(46.43±27.26)/h in the middle-juvenile patients.The mean value of the NREM stage between the two groups was similar.The REM of the senile patients was higher than that of the middle-juvenile patients[(13.08±7.37)% vs(9.78±7.23)% ].Conclusion Senile patients with obstructive sleep apnea-hypopnea syndrome should first select non-invasive treatment.
