  • Title: Oxygen exchange in silicone rubber capillaries.
    Author: Heineken FG, Predecki PK, Filley GF.
    Journal: J Bioeng; 1978 Jun; 2(3-4):195-204. PubMed ID: 711713.
    Abstract:
    Capillaries of 7 and 12.5 mu diameter have been fabricated in silicone rubber. Whole blood treated with heparin has been perfused through these capillaries. Under flowing conditions, no clotting or other clumping effects have been observed and red cells appear to maintain a constant velocity. Oxygen transfer data to and from saline perfusing the 12.5 mu diameter capillaries have been obtained in order to determine how rapidly O2 will permeate the silicone rubber film. The data indicate that the capillaries simulate lung tissue oxygen exchange and will allow for the first time the experimental determination of oxygen exchange kinetics in flowing whole blood.
