Blood Oxygenation. I. The Kolff Apparatus. II. Multiple Horizontal Rotating Cylinders. *

Abstract

Summary

1. Cellulose sausage casing presents too great a barrier to the diffusion of O₂ into blood to make the Kolff apparatus an efficient oxygenator. 2. Although the Kolff machine mixes blood and oxygen, the foaming which results is excessive for an oxygenator. 3. Horizontal revolving cylinders oxygenate blood efficiently enough to make their use in animal perfusion practicable, but foaming is excessive.
