近年发现肝硬化病人的氧摄取(氧耗)降低,且氧耗异常地依赖于由心输出量及动脉血氧含量决定的氧转运。这些发现提示肝硬化患者可能存在亚临床组织低氧症。作者给予肝硬化病人吸氧以提高动脉血氧含量,观察能否增加氧耗,同时研究吸氧对压力感受器、心率和血压的反射调节。 In recent years, patients with cirrhosis of the liver found that oxygen uptake (oxygen consumption) decreased, and oxygen consumption abnormally depends on cardiac output and arterial oxygen content of oxygen transport. These findings suggest that subclinical hypoxia may exist in patients with cirrhosis. The authors give patients with cirrhosis of the oxygen to improve arterial oxygen content, to observe whether the increase in oxygen consumption, while studying the baroreceptor oxygen pressure, heart rate and blood pressure reflex regulation.
