肺泡气-动脉血氧分压差(P_(A-a)O_2)是评价肺内气体交换功能的有价值的指标。我们分析了44例慢性肺心病并发呼吸衰竭P_(A-a)O_2,结果显示出 P_(A-a)O_2的改变与病情严重性有相关。这对治疗和预后判断有一定参考意义。一、资料与方法1.性别,年龄 44例中,男34例,女10例。年龄24～83岁,平均58.7岁,其中55～70岁者共31例,占70%。2.基础病因仅2例为多发性肺囊肿,余42例均为慢性支气管炎并阻塞性肺气肿,最后发生肺心病。病史7～50年。
Alveolar gas-arterial partial pressure of oxygen (P_ (A-a) O_2) is a valuable indicator for evaluation of gas exchange in the lung. We analyzed 44 cases of chronic pulmonary heart disease complicated with respiratory failure P_ (A-a) O_2, the results showed that P_ (A-a) O_2 changes and the severity of the disease are related. This treatment and prognosis have some reference value. First, the data and methods 1 gender, age 44 cases, 34 males and 10 females. Aged 24 to 83 years, mean 58.7 years, of which 55 to 70 years old in a total of 31 cases, accounting for 70%. 2. The basic cause of only 2 cases of multiple pulmonary cysts, more than 42 cases of chronic bronchitis and obstructive pulmonary emphysema, the final occurrence of pulmonary heart disease. History of 7 to 50 years.
