Abstract:
Objective To evaluate the effect of pulmonary function test on infants with obstructive sleep apnea-hypopnea syndrome (OSAHS). Methods Forty-eight patients were divided into two groups based on physical examination. Pulmonary function were measured in 48 patients. Age-matched healthy infants were enrolled as controls. The parameters included ratio of volume to PEF to total expiratory volume(VPTEF/VE,tPTEF/tE),inspiratory time/expiratory time(TI/tE),inspiratory time/total respiratory time(TI/Ttot),ratio of 50% of the tital inspiratory flow to tital volume(TIF_ 50 /V_T),mean inspiratory flow(V_T/TI),function capacity(FRCp),resistance effective(Reff).Results TI/Ttot,ratio of 50% of the tital expiratory flow to 50% of the tital inspiratory flow(TEF_ 50 /TIF_ 50 ),FRCp,Reff were significantly higher in patients compared with controls(P
