【摘要】 目的：研究加温湿化呼吸治疗仪在急诊急性呼吸衰竭患者中的应用效果。方法：采用前瞻性随机对照试验，选取2019年1月—2020年1月右江民族医学院附属医院急诊科收治的64例急性呼吸衰竭患者。随机分为试验组和对照组，各32例。试验组接受加温湿化呼吸治疗仪治疗，对照组接受无创呼吸机治疗，对比两组患者的生命体征、床边血气分析结果及相关并发症。结果：试验组治疗后呼吸频率、心率低于对照组，血氧饱和度高于对照组，差异有统计学意义（P<0.05）。试验组治疗后酸碱值（pH）、动脉血氧分压（PaO₂）、PaO₂/吸入氧浓度（FiO₂）高于对照组，动脉血二氧化碳分压（PaCO₂）低于对照组，差异有统计学意义（P<0.05）。试验组并发症发生率低于对照组，差异有统计学意义（P<0.05）。结论：加温湿化呼吸治疗仪在急诊急性呼吸衰竭患者中的应用效果理想，可明显改善患者的生命体征与床边血气分析结果，且能降低并发症发生率。更多还原

【Abstract】 Objective:To study the effect of warming humidification respiratory therapy instrument in emergency patients with acute respiratory failure.Method:A prospective randomized controlled trial was conducted to select 64 patients with acute respiratory failure from the Emergency Department of the Affiliated Hospital of Youjiang Medical University for Nationalities from January 2019 to January 2020.The patients were randomly divided into experimental group and control group,with 32 casess in each group.The experimental group received treatment with a heated and humidified breathing therapy device,while the control group received treatment with a non-invasive ventilator.The vital signs,bedside blood gas analysis results and related complications of the two groups of patients were compared.Result:After treatment,the respiratory rate and heart rate of the experimental group were lower than those of the control group,and the blood oxygen saturation was higher than that of the control group.The difference was statistically significant （P<0.05）.After treatment,the pH value,arterial partial pressure of oxygen （PaO₂）,and PaO₂/ inhaled oxygen concentration （FiO₂） in the experimental group were higher than those in the control group,while the arterial partial pressure of carbon dioxide （PaCO₂） was lower than that in the control group.The differences were statistically significant （P<0.05）.The incidence of complications in the experimental group was lower than that in the control group,and the difference was statistically significant （P<0.05）.Conclusion:The application effect of the heated and humidified respiratory therapy device in emergency patients with acute respiratory failure is ideal.It can significantly improve the vital signs and bedside blood gas analysis results of patients,and can reduce the incidence of complications.更多还原
