【摘要】 本文在50例健康人及71例慢性肺源性心脏病人（其中肺性脑病21例）动、静脉血气分析基础上,进一步对动、静脉血氧分压差值（Pa-vDO₂）作了统计与对比分析。结果发现肺源性心脏病人的Pa-vDO₂比健康人明显减少,而肺性脑病患者更低,Pa-vDO₂值的变化与病情预后有密切关系。本文并论述了Pa-vDO-2值的临床意义。更多还原

【Abstract】 Blood gas values of 50 cases of healthy persons and 71 patients with chronic cor pulmonale were analysed.21 cases were complicated by pulmo-encephalopathy. Pa-vDO2 value was obviously decreased in those 71 patients and even much lower for the 21 patients with pulmo-encephalopathy. Their average values were 3.6±2.1 1.3±0.8 and 7.4±1.2 kPa respectively, P<0.01).The variation of Pa-vDO2 p< for patients with pulmo-encephalopathy is closely connected with the prognosis.更多还原
