Comparison of Effect of Nasal High-flow Oxygen Therapy and Non-invasive Ventilator-assisted Ventilation in Patients with Type II Respira-tory Failure
Objective To analyze the effects of nasal high-flow oxygen therapy and non-invasive ventilator-assisted ventilation in patients with type II respiratory failure.Methods A total of one hundred patients with type II respiratory failure admitted to Yizheng People's Hospital from January 2022 to December 2023 were simple randomly selected as the study objects and divided into two groups according to random number table method.The control group(50 cases)received non-invasive ventilator-assisted ventilation,and the observation group(50 cases)received nasal high-flow oxygen therapy.The clinical therapeutic indexes,blood gas indexes,complications and prognosis of the two groups were compared.Results After treatment,there was no statistically significant difference in clinical treatment indexes between the two groups(P>0.05).After treatment,there was no statistically significant difference in oxygen partial pressure,carbon dioxide partial pressure and pH value between the two groups(all P>0.05).The complication rate of observation group(6.00%)was lower than that of control group(22.00%),and the difference was statistically signifi-cant(χ2=5.316,P<0.05).There was no statistically significant difference in intubation rate and mortality between the two groups(both P>0.05).Conclusion In patients with type II respiratory failure,both nasal high-flow oxygen therapy and non-invasive ventilator-assisted ventilation can effectively improve dyspnea symptoms and blood gas indexes of patients,but nasal high-flow oxygen therapy has fewer complications and better treatment tolerance.
