Oxygen transport in patients with Friedreich's ataxia.
The hypothesis is that an abnormal oxygen-hemoglobin dissociation curve is a primary or a secondary defect in patients with Friedreich's ataxia was investigated in 12 subjects with this disease. Hemoglobin and P50 were measured and compared with age and sex matched controls. The mean hemoglobin concentration was 14.2 g% and the P50 was 26.25 torr for the patients and 13.8 g% and 26.27 torr in the controls. These results indicate that the oxygen transport system is normal in this disease and likely exclude an abnormal oxygen dissociation curve as a primary or a secondary factor in the pathophysiology of the cardiomyopathy and the neuromyopathy found in this disease.
