Quantitative analysis of oxygen transport in blood requires accurate values for the oxygen diffusion coefficient (D) in blood plasma and in whole blood. There has been a controversy over the effect of plasma composition on D. One group [1] has found a precipitous drop in plasma D with small changes in the concentrations of various common plasma proteins. This would have profound physiological and pathological consequences [2,3]. Other groups [4,5,6] have found D in solutions of plasma proteins to be well-behaved, decreasing regularly with increasing protein concentration. None of these measurements, however, have been made on natural human plasma. The present study, which used freshly drawn human plasma, found that D decreased almost linearly with total protein content, even in very abnormal plasmas. It also found that the D in plasma and its serum were identical and that serum could be stored frozen for several months without changing its D. From measurements of D in plasma, and literature values for D in packed red blood cells, D in whole blood was estimated.
