慢性阻塞性肺疾病是以气流受限为主要特征的肺部疾病,临床死亡率较高,呼吸衰竭是该病最为常见的合并症之一,原因主要是气道阻塞会致使患者呼吸问题的加重,再加上患者本身极容易发生高碳酸血症、缺氧缺血、电解质紊乱甚至营养不良等问题,因此会导致呼吸肌疲劳,引发呼吸衰竭。无创正压通气是一种辅助治疗手段,主要为患者提供呼吸支持。与有创正压通气相比,其在慢性阻塞性肺疾病合并Ⅱ型呼吸衰竭患者临床治疗中的应用更具有普遍性。本文首先分析了应用无创正压通气治疗慢性阻塞性肺疾病合并Ⅱ型呼吸衰竭的背景及其发展情况,之后详细分析了无创正压通气在慢性阻塞性肺疾病合并Ⅱ型呼吸衰竭临床治疗应用的优势,最后介绍了无创正压通气的应用方法及其取得的效果。
Chronic obstructive pulmonary disease (COPD) is a lung disease characterized by limited air flow and has a high clinical mortality rate. Respiratory failure is one of the most common comorbidities of the disease. The main reason is that airway obstruction causes the patient’s respiratory problems to worsen , Coupled with the patient itself is very prone to hypercapnia, hypoxia and ischemia, electrolyte imbalance or malnutrition and other issues, it will lead to respiratory muscle fatigue, trigger respiratory failure. Noninvasive positive pressure ventilation is an adjuvant treatment, mainly to provide respiratory support for patients. Compared with invasive positive pressure ventilation, its application in clinical treatment of patients with chronic obstructive pulmonary disease and type 2 respiratory failure is more common. This paper first analyzes the background and development of noninvasive positive pressure ventilation in the treatment of chronic obstructive pulmonary disease (COPD) complicated with type II respiratory failure, and then analyzes in detail the clinical application of noninvasive positive pressure ventilation in COPD with type II respiratory failure Advantage, and finally introduces the application of noninvasive positive pressure ventilation and its effect.
