Changes of Nasal resistance in obstructive sleep apneasyndrome / 中国基层医药

ABSTRACT

Objective To investigate the obstructive sleep apnea syndrome ( OSAHS) associated with nasal resistance.Methods 30 cases with obstructive sleep apneahypopnea syndrome ( OSAHS ) in the OSAHS group, 30 cases with snoring but without OSAHS in the snoring group and 30 cases with normal group based on polysomnog-raphy were detected the nasal resistance.Results The index of thsnoring index[(42.7 ±27.3),(19.4 ±18.5), AHI(38.7 ±30.2),(5.9 ±1.6)and Resl+r(1.63 ±1.11)Pa· s-1· mL-1,(0.72 ±0.31)Pa· s-1· mL-1] in OSAS group and snoring group were significantly higher than those of the normal group ( t=6.451,7.444,7.698,all P0.05),wake times (r=0.083,P>0.05) and lowest SaO2(r=0.105,P>0.05)were not significantly correlated;The cases with OSAS cephalometric.The results suggest majority snoring symptoms significantly more at supine posi-tion in OSAS.Conclusion Nasal resistance increased,which may be associated with the occurrence in patients with OSAHS.
