肺性脑病是慢性肺胸疾病严重并发症之一,伴有缺氧与二氧化碳潴留,出现意识障碍,精神症状,病死率很高,是肺心病患者死亡的主要原因。因此早期诊断及早期防治此病,对降低肺心病的死亡率是有重要意义的。近年来我国各地区在抢救肺性脑病方面积累了许多经验,使肺性脑病病死率有所下降。肺性脑病的发生机理肺性脑病主要是由于肺心病急性发作期低血氧症、严重高碳酸血症、酸硷平衡失调等所引起的。根据国内某些地区资料分析:当血pH值为7.36,动脉血二氧化碳分压高于60毫米汞柱时可出现嗜睡;当pH值为7.33,二氧化碳分压高于70毫米汞柱则
Pulmonary encephalopathy is one of the serious complications of chronic pulmonary disease, accompanied by hypoxia and carbon dioxide retention, disturbance of consciousness, mental symptoms, high mortality is the main cause of death in patients with cor pulmonale. Therefore, early diagnosis and early prevention and treatment of the disease, to reduce the mortality of pulmonary heart disease is of great significance. In recent years, many regions in our country have accumulated a great deal of experience in salvage of pulmonary encephalopathy, resulting in a decrease in the mortality of pulmonary encephalopathy. Pulmonary encephalopathy mechanism of pulmonary encephalopathy is mainly due to acute episodes of pulmonary heart disease hypoxemia, severe hypercapnia, acid-base balance disorders caused. According to some domestic data analysis: When the blood pH value of 7.36, partial pressure of arterial carbon dioxide higher than 60 mmHg when sleepiness may occur; when the pH value is 7.33, the partial pressure of carbon dioxide is higher than 70 mmHg
