慢性肺心病急性发作期有80～97.5%的患者可发生呼吸衰竭。在肺心病的死因中,主要为肺性脑病占33.65%。因此,呼吸衰竭的治疗,尤其是肺性脑病的抢救,对降低肺心病的病死率是很重要的。我们在1975年以间歇辅助通气治疗肺性脑病,以后又以持续吸氧、间歇辅助通气治疗呼吸衰竭均取得较好的疗效。现将进一步研究的结果报告如下。 Chronic pulmonary heart disease acute exacerbation of 80 ~ 97.5% of patients with respiratory failure can occur. In the cause of pulmonary heart disease, the main pulmonary encephalopathy accounted for 33.65%. Therefore, the treatment of respiratory failure, especially the treatment of pulmonary encephalopathy, is very important to reduce the mortality of pulmonary heart disease. We in 1975 with intermittent adjuvant ventilation for the treatment of pulmonary encephalopathy, and later continued to oxygen, intermittent assisted ventilation for respiratory failure have achieved better results. The results of further studies are reported below.
