Title: [abstract] SIZE DISTRIBUTION OF INTRAVASCULAR BUBBLES INDUCED BY DECOMPRESSION.
Author: Butler, BD; Hills, BA; Sutton, TE
Abstract: Although in most cases, bubbles found in the venous system during decompression are trapped in the lungs, it is still most desirable to know their size distribution in attempting to predict their effects. Dogs (18-24 kg) were anaesthetised and compressed to various depths ranging from 120 to 220 faw for exposures lasting to 3 hours. Prior to compression cannulae were placed into the sinus venarum cavarum for sampling venous blood containing the decompression-induced bubbles. The cannula was connected to a high-pressure blood sampling valve which passed through the chamber wall. Size distributions of the bubbles were determined from 50 ml. aliquots drawn from the venous cannula for periods up to 2 hours post decompression. A Coulter-counter was used for bubble size measurement. Bubble sizes ranged from 19-179pm for the lower end of the scale while larger bubbles. hundreds of microns in diameter. were measured after various intervals post-decompression. Quantities of smaller bubbles usually appeared immediately post-decompression while larger bubbles tended to appear later. The research reported here has been supported under the Office of Naval Research with funds provided by the Naval Medical Research and Development Command.
