Study on the treatment of elderly chronic obstructive pulmonary disease complicated with type IIrespiratory failure by high-flow heating and humidifying oxygen inhalation
高流量加温湿化吸氧治疗老年慢阻肺合并II型呼衰的研究

摘要

目的 探究使用高流量加温湿化吸氧装置治疗老年慢阻肺合并II型呼吸衰竭的治疗效果。方法选取2018年5月-2020年5月在本院治疗的200例老年慢阻肺合并II型呼吸衰竭患者为研究对象，随机抽选其中100例患者为对照组和100例实验组形式，其中对照组患者使用常规药物与低流量氧疗形式完成治疗过程，实验组患者使用高流量加温湿化吸氧治疗法，记录患者治疗后一天、两天、三天后的心率指标、呼吸频率指标和临床症状改善情况，对动脉血气做出分析，并判断患者术后是否存在不良反应现象。结果 对照组患者在治疗后心率与呼吸频率均弱于实验组患者，临床症状改善效果不明显，仍存在少数患者有呼吸衰竭、咳痰、气短现象，实验组治疗效果更好。结论 使用高流量加温湿化吸氧治疗法对老年慢阻肺合并II型呼吸衰竭治疗效果好于低流量氧疗法，可在临床上大面积推广。

Abstract

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.
