Efficacy Analysis of High-Flow Nasal Cannula Oxygen Therapy in Patients with Type I Respiratory Failure
Objective To analyze the efficacy of high-flow nasal cannula oxygen therapy in patients with type I respiratory failure.Methods Seventy-six patients with type I respiratory failure admitted to Nanyang Central Hospital from October 2022 to October 2023 were included as study subjects.They were divided into groups using a random odd-even number method,with 38 odd-numbered cases in the control group receiving conventional mask oxygen support,and 38 even-numbered cases in the study group receiving High-flow nasal cannula oxygen therapy.Blood gas analysis indicators[partial pressure of arterial oxygen(PaO2),Partial Pressure of Carbon Dioxide(PaCO2),arterial oxygen saturation(SaO2)],oxygen therapy time,ICU stay duration,incidence of oxygen therapy-related complications,and comfort scale scores before and after treatment were compared between the two groups.Results There were no statistically significant differences in PaO2,PaCO2,and SaO2 levels between the groups before treatment(P＞0.05).After treatment,PaO2 and SaO2 levels in both groups were higher than before treatment,and PaCO2 levels were lower than before treatment.The PaO2 and SaO2 levels in the study group were higher than those in the control group,and the PaCO2 level was lower than that in the control group,with statistically significant differences(P＜0.05).The oxygen therapy time and ICU stay duration in the study group were shorter than those in the control group,with statistically significant differences(P＜0.05).The incidence of oxygen therapy-related complications in the study group(5.26%)was lower than that in the control group(23.68%),with statistically significant differences(P＜0.05).There were no statistically significant differences in comfort scale scores between the groups before treatment(P＞0.05).After treatment,the comfort scale scores in both groups were higher than before treatment,and the scores in the study group were higher than those in the control group,with statistically significant differences(P＜0.05).Conclusion High-flow nasal cannula oxygen therapy is more effective in patients with type I respiratory failure,significantly improving arterial blood gas indicators,shortening oxygen therapy time and hospital stay,enhancing patient comfort,and reducing oxygen therapy-related complications,making it worthy of clinical application.
