潮气呼吸肺功能在婴幼儿腺病毒肺炎中的应用

目的 探究潮气呼吸肺功能在婴幼儿腺病毒肺炎中的应用效果.方法 选取50例腺病毒肺炎患儿作为观察组,另随机抽选常规检查的健康婴幼儿作为对照组.所有研究对象均进行潮气呼吸肺功能检查,对比两组的肺功能各项指标[呼吸频率(RR)、潮气量(VT)、吸气时间(Ti)、潮气呼气峰流速(PTEF)、到达潮气呼气峰流速的时间/呼气时间(...

Application of tidal breathing pulmonary function in infants with adenovirus pneumonia

Objective To investigate the practical effect of tidal breathing pulmonary function in infants with adenovirus pneumonia.Methods There were 50 infants with adenovirus pneumonia selected as the observation group,and another healthy subjects as the control group.All subjects underwent tidal breathing and lung function tests.The pulmonary function indicators[respiratory frequency(RR),tidal volume(VT),inspiratory time(Ti),peak tidal expiratory flow(PTEF),time to tidal peak expiratory flow/expiratory time(TPTEF/Te),expiratory volume at tidal peak expiratory flow/expiratory time(VPTEF/Ve)and tidal peak expiratory flow/expiratory time/expiratory time(PTEF/Ve)]of the two groups were compared.Results The RR(34.16±7.14)times/min,PTEF(136.48±18.01)ml/s and PTEF/Ve(1.58±0.29)%of the observation group were higher than(22.64±5.01)times/min,(123.54±10.64)ml/s and(1.31±0.35)%of the control group,Ti(0.78±0.12)s was shorter than(0.84±0.13)s of the control group,and VT(6.78±0.54)ml/kg,TPTEF/Te(38.97±6.98)%and VPTEF/Ve(40.13±9.13)%were lower than(8.46±0.85)ml/kg,(45.16±8.46)%and(46.58±7.15)%of the control group.All the difference was statistically significant(P<0.05).Conclusion In the acute stage,infant adenovirus pneumonia shows increased small airway resistance,decreased tidal volume,and mixed ventilation dysfunction.Pulmonary function test is an ideal method to monitor the condition of infant adenovirus pneumonia.
