本文报道了我院自1974年11月至1976年2月慢性肺心病163例计333例次的血气变化及其与临床关系。在333例次测定中,有4.2%血气完全正常,有19.2%仅表现低氧血症。因此,认为对于有慢性咳嗽的病人低氧血症是肺心病早期诊断的一个重要指标。在酸碱类型中,以呼吸性酸中毒为主,占48.1%;其次是呼吸性酸中毒并代谢性碱中毒,占28.6%;代谢性碱中毒占12.9%。并分析了肺心病人碱中毒的原因及其危害性,以引起临床注意。在血气与临床关系上,呼吸性酸中毒这一类型中肺性脑病与心衰占1/2以上,达部分病人死亡率最
This article reports the changes of blood gas in 163 cases of chronic pulmonary heart disease in our hospital from November 1974 to February 1976 and the clinical relationship between them. In 333 sub-tests, 4.2% of the blood gas completely normal, 19.2% only showed hypoxemia. Therefore, hypoxemia in patients with chronic cough is considered to be an important indicator of early diagnosis of pulmonary heart disease. Among the acid-base types, respiratory acidosis was the most common, accounting for 48.1%; followed by respiratory acidosis and metabolic alkalosis, accounting for 28.6%; and metabolic alkalosis accounting for 12.9%. And analysis of pulmonary heart disease causes of alkalosis and its harmfulness, to attract clinical attention. In the relationship between blood gas and clinical, respiratory acidosis in this type of pulmonary encephalopathy and heart failure accounted for more than 1/2, up to some patients with the most mortality
