Conclusion: Continuous warming humidification to air passage can reduce the form of sputum crust, incidence of irritable cough, blooding in air passage, sputum aspiration and hypoxia caused by sputum aspiration as well. 结论:加温持续气道湿化可明显减少痰痂形成,刺激性咳嗽,气道出血及肺部感染的发生,并可减少吸痰次数,减轻吸痰所致的低氧血症程度并缩短其持续时间及住院天数。
Results: sputum crust, irritable cough and blooding in air passage were less seen in treated group than control group ( P < 0.01). 结果:治疗组形成痰痂、发生刺激性咳嗽、气道出血的例数和吸痰次数均明显少于对照组(P<0.01);
There are 22 cases with cough onset in the early morning, 9 cases at the night, which is irritable dry cough. 咳嗽多见于清晨者22例,夜间者9例,多为刺激性干咳。
Results Irritable cough and pulmonary infection were less in heating vapor humidification group than in dripping humidification group, oxygen partial pressure and heart rate reduced either. 结果加热蒸汽加温加湿法较气道内直接滴注加湿法,能够减少人工气道患者的刺激性咳嗽和肺部感染的发生,提高氧分压和氧饱和度,降低心率。
