Abstract：Objective To compare the effect of mechanical humidifier and oxygen atomization inhalation humidification for artificial airways. Methods Totally 74 critical patients established the artificial airway for more than 48 hours in our hospital between February 2017 and February 2018 were selected, and randomly divided into a control group and a study group, each of 37. The control group was given the oxygen atomization inhalation, while the study group was moisturized the airway using the mechanical humidifier. The wetting effect was compared between two groups. Results The sputum viscosity and the positive rate of sputum bacteria culture after airway humidification of the study group were significantly lower than those of the control group (Z=-6.849, P＜0.001;χ2=6.618, P=0.010). Moreover, the comfort of the study group was significantly higher than the control group (χ2=9.784, P=0.002). Conclusion For patients with artificial airway, the mechanical humidifying device is superior to the oxygen atomizing inhalation in humidifying the airway.
