Abstract
Objective To investigate the effect of high flow oxygen therapy system on the incidence of hospital acquired pneumonia in patients with tracheotomy.Methods 70 patients who separated from the ventilator of tracheoto-my were randomly divided into treatment group (humidified oxygen humidified high flow)and conventional group (tra-ditional artificial humidification oxygen mask)35 cases,arterial oxygen partial pressure (PaO2 ),arterial partial pressure of carbon dioxide (PaCO2 ),oxygen saturation (SaO2 ),the incidence of airway humidification effect of pH value,satis-faction rate and complication were compared between two groups.Results Before the treatment,humidified oxygen ther-apy group and normal group of PaO2 ,PaCO2 ,SaO2 ,pH value of the difference was not statistically significant (P >0.05);4 h treatment,after the treatment of 24h,PaO2 ,SaO2 humidification oxygen therapy group were higher than that in control group (P <0.05 ),there was no significant difference between PaCO2 and the conventional group (P >0.05);after 1 2 h treatment,the two groups of patients with airway humidification was evaluated,humidification oxygen therapy group airway humidification satisfaction was 80% higher than the conventional group 54.29% (P <0.05);hu-midification oxygen therapy group excessive airway humidification of 0% lower than the conventional group 1 1 .43%(P <0.05);the treatment process,oxygen humidification treatment group,the complication rate was 1 1 .43% lower than the conventional group 40 (P <0.05),humidification oxygen therapy group occurs in hospital acquired pneumonia in 6 cases (1 7.1 4%)of 1 4 cases lower than the conventional group (40%),the difference was statistically significant (P <0.05).Conclusion High flow humidification oxygen therapy system can effectively reduce the incidence of hospital ac-quired pneumonia in patients with tracheotomy and maintain stable blood gas levels.关键词
