Objective To explore the therapeutic effect of high-flow heated humidified oxygen inhalation device in the treatment of elderly chronic obstructive pulmonary disease complicated with type II respiratory failure. Methods 200 elderly patients with chronic obstructive pulmonary disease combined with type II respiratory failure who were treated in our hospital from May 2018 to May 2020 were selected as the research objects, and 100 patients were randomly selected as the control group and 100 cases in the experimental group. Among them, the patients in the control group were treated with conventional drugs and low-flow oxygen therapy, while the patients in the experimental group were treated with high-flow heating and humidifying oxygen therapy. and clinical symptoms improvement, analyze the arterial blood gas, and determine whether the patient has adverse reactions after surgery. Results The heart rate and respiratory rate of the patients in the control group were weaker than those in the experimental group after treatment, and the clinical symptoms were not significantly improved. There were still a few patients with respiratory failure, expectoration, and shortness of breath. The experimental group had better treatment effect. Conclusion The use of high-flow heating and humidifying oxygen therapy for elderly patients with chronic obstructive pulmonary disease complicated with type II respiratory failure is more effective than low-flow oxygen therapy, and it can be widely used in clinical practice.
