本文研究高频喷射通气(HFJV)在慢性肺原性心脏病中的应用。结果表明HFJV对Ⅰ型呼衰改变缺氧效果显著,不导致CO_2潴留。Ⅱ型呼衰HFJV组所有病例PaO_2均达满意水平,疗效明显优于HFJV/呼吸兴奋剂及低流量吸氧组,不导致PaCO_2升高。HFJV时气管内氧并非高浓度氧。本文结论:HFJV是一种使用方便,安全可靠的机械通气方式,对肺心病Ⅰ型及Ⅱ型呼衰均有显著疗效,不导致CO_2潴留。
This article studies the application of high frequency jet ventilation (HFJV) in chronic pulmonary heart disease. The results showed that HFJV on type Ⅰ respiratory failure to change the effect of hypoxia significantly, does not lead to CO_2 retention. All patients with type Ⅱ respiratory failure HFJV group all reached satisfactory levels of PaO_2, the effect was significantly better than HFJV / respiratory stimulants and low flow oxygen group, does not lead to PaCO_2 increased. HFJV when the trachea oxygen is not a high concentration of oxygen. Conclusion: HFJV is a safe, reliable and mechanical ventilation method. It has significant effect on type Ⅰ and type Ⅱ respiratory failure of pulmonary heart disease without causing CO2 retention.
