The Effect of Refined Airway Management on HFNC Treatment of EICU Acute Hypoxic Type I Respiratory Failure Patients
Objective To explore the effect of refined airway management on the oxygenation and blood gas of patients with acute hypoxic type I respiratory failure in the Emergency Department Intensive Care Unit(EICU)treated with High Flow Nasal Cannula(HFNC).Methods 112 patients with acute hypoxic type I respiratory failure admitted to Zhoukou Central Hospital from January 2022 to December 2022 were selected as the research subjects.According to the random number table method,they were divided into the control group(56 cases,treated with HFNC)and the observation group(56 cases,combined with refined airway management on the basis of the control group).The oxygenation index and heart rate(HR),respiratory rate(RR),blood gas indicators[carbon dioxide partial pressure(PaCO2),arterial oxygen partial pressure(PaO2),blood oxygen saturation(SaO2),pH value],comfort level[General comfort questionnaire(GCQ)]changes before and after intervention(3 days after intervention)of the two groups were compared;the difference in adverse reactions during the intervention of the two groups was explored.Results After intervention,the oxygenation index of both groups increased,and the vital signs(HR,RR)decreased.The oxygenation index of the observation group was higher than that of the control group,and the HR and RR indicators were lower than those of the control group,and the differences were statistically significant(P＜0.05).After intervention,the PaO2,SaO2,and pH indicators of both groups increased,and the PaCO2 indicators decreased.The PaO2,SaO2,and pH indicators of the observation group were higher than those of the control group,and the PaCO2 indicators were lower than those of the control group,and the differences were statistically significant(P＜0.05).After intervention,the GCQ scores of both groups increased,and the GCQ scores of the observation group were higher than those of the control group,and the differences were statistically significant(P＜0.05).During the intervention,the incidence of gastrointestinal bloating,aspiration pneumonia,mask pressure site injury,oropharyngeal discomfort,and ventilator-associated pneumonia(VAP)in the two groups was not statistically significant(P＞0.05).Conclusion Refined airway management can effectively improve the oxygenation index and blood gas indicators of patients with acute hypoxic type I respiratory failure in EICU treated with HFNC,and help improve their comfort level.
