Abstract

Using a wetted-wall column one meter in length to produce a falling film, whole blood was oxygenated with a countercurrently flowing stream of pure oxygen. From the derived trans­port equation describing this operation, overall diffusion coefficients were calculated for oxygen in whole blood. For a l-inch diameter column, the arithmetic average value for the diffusion coefficient was 2.07 × 10−5 cm2/sec in the 87 to 96 per cent saturation range. For the 1/2-inch column, the average diffusion coefficient was 2.13 × 10−5 cm2/sec in the 72 to 96 per cent range. An arithmetic average of all the data for both columns in the 72 to 96 per cent range was 2.10 × 10−5 cm2/sec at 30°C with a standard deviation of 0.42 × 10−5 cm2/sec.

Limitations of the model used are discussed and a brief review of other work in this area is presented.
