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.
