In hypercapnic chronic respiratory failure red cell volume correlates with the arterial oxygen tension during the quiescent phase of the disease. During an acute exacerbation measurement of the red cell volume can give a reasonable index of the arterial oxygen tension existing in the previous quiescent state. This level of arterial oxygen tension appears to determine the tolerance of the individual to treatment with oxygen.
在高碳酸血症性慢性呼吸衰竭中,红细胞容量与疾病静止期的动脉血氧张力相关。在急性加重期,测量红细胞容量可合理反映先前静止期存在的动脉血氧张力。这种动脉血氧张力水平似乎决定了个体对氧疗的耐受性。
