| Abstract: | The effect of hemodialysis on oxygen delivery has been assessed in nine patients. During hemodialysis the arterial PO2 decreased from 76.89 mm Hg to 69.03 mm Hg. There was also an increase in pH from 7.39 to 7.49 which resulted in an increase in the affinity of the blood for oxygen. In the absence of compensatory changes this could result in a 17.9% decrease in oxygen delivery. This could be hazardous in patients who are already anemic particularly in the presence of cardiac or respiratory insufficiency. |
