Abstract：Objective To explore the application effect of warm humidification oxygen therapy in non-artificial airway management in elderly stroke patients.Methods A tatal of 600 elderly patients with non-artificial airway stroke who admitted to our hospital from June 2016 to June 2018 were selected.They were randomly divided into the observation group and the control group, 300 cases in each group.The observation group was provided with a warm humidifying oxygen therapy program consisting of a venturi mask and a humidifier of MR410, MR760 or MR810 or a breathing tube for the ventilator, and the control group was provided with a traditional nasal catheter or mask oxygen therapy program,the phlegm viscosity, sputum callus formation, oxygen therapy effect and pulmonary infection in the two groups were compared.Results The sputum consistency of the observation group was better than that of the control group (P<0.05).The sputum scab formation rate, pulmonary infection rate and arterial carbon dioxide partial pressure (PaCO2) in the observation group were all lower than those in the control group, and the differences were statistically significant (P<0.05).The blood oxygen saturation (SpO2) of the observation group was higher than that of the control group, and the difference was statistically significant (P<0.05).Conclusion Venturi warm humidifying oxygen therapy device can effectively improve the effect of oxygen therapy, humidifying the airway, reduce the incidence of pulmonary infection, and improve the comfort and compliance of patients with oxygen therapy.
