由于慢性呼吸衰竭急性发作(Acute on Chronic Respiratory Failure,ACRF)患者基本的气体交换障碍是通气过低及通气血流比失调(假设不存在严重的肺炎及肺水肿),因此病员的低氧血症对吸氧有良好的反应。但临床医生却常常不及时给予合适的氧疗。毫无疑问,许多教科书及综述性文章均指出慢性梗阻性肺部疾病(COPD)患者呼吸中枢的兴奋主要靠低氧血症刺激来维持,如果缺氧纠正可能引起呼吸停止。尽管没有令人信服的证据,但这种观点却被广泛接受。
As the basic gas exchange disorder in patients with Acute on Chronic Respiratory Failure (ACRF) is hypoventilation and ventilatory-to-blood-flow imbalance (assuming no severe pneumonia and pulmonary edema), the patient’s hypoxemia Have a good response to oxygen. However, clinicians often fail to give proper oxygen therapy in time. Undoubtedly, many textbooks and review articles point out that the excitement of the respiratory center in patients with chronic obstructive pulmonary disease (COPD) is mainly sustained by hypoxemic stimulation, which may cause respiratory arrest if hypoxia is corrected. Although there is no convincing evidence, but this view has been widely accepted.
