Title: [abstract] COUNERPERFUSION SUPERSATURATION.
Author: Hills, BA
Abstract: An extensive analysis of gas transfer under steady-state conditions shows that a state of gaseous supersaturation can be induced in tissue when two inert gases are transmitted in opposite directions across any system comprising a diffusion barrier adjacent to a zone of limited convective capacity. This has many implications for bubble formation in vivo and can explain the occurrence of symptoms of decompression sickness without decompression. This model has two distinct advantages over that based upon counter-diffusion in that it is no longer necessary to postulate an extensive lipid layer and the supersaturation is now greatest in the blood -where bubbles are found experimentally. Thus counter-perfusion supersaturation would appear to offer a better explanation for both vestibular "bends" in the absence of decompression and the bubbles in venous blood from cutaneous tissues when the skin is exposed to a more diffusible inert gas than the one inspired.
