二型呼吸衰竭病人氧疗的时候,吸氧浓度不要过高,吸氧的浓度不要超过2个立升,否则会出现呼吸抑制危险。除此之外,二型呼吸衰竭氧疗的注意事项还有下面内容:氧疗浓度不当:慢性呼衰多属Ⅱ型,既有缺氧,又有二氧化碳潴留,此时呼吸中枢对二氧化碳的刺激已不敏感,主要依靠缺氧来维持其兴奋性。

What should be paid attention to when breathing oxygen in patients with type 2 respiratory failure
During oxygen therapy for patients with type II respiratory failure, The oxygen concentration should not be too high, The concentration of oxygen should not exceed 2 liters, Otherwise, there is a risk of respiratory depression. besides, The following points should be paid attention to in oxygen therapy of type II respiratory failure: improper concentration of oxygen therapy: chronic respiratory failure belongs to type II, There is hypoxia, Carbon dioxide retention * At this time, the respiratory center is not sensitive to the stimulation of carbon dioxide, It mainly depends on hypoxia to maintain its excitability.
