A Compression-Decompression Schedule for Producing Dysbaric Stress in Mature Rats

Abstract

A need arose to develop a compression-decompression table that would insure a proper degree of severe decompression stress in rats. Severe decompression stress has been defined as that stress which is neither safe, allowing complete (100%) survival, nor excessively hazardous (explosive) resulting in a 90-100% death rate within one hour post-surfacing. By these criteria, then a 66% survival rate documents severe decompression. This report details a schedule with 72 minutes of chamber time which will routinely produce severe decompression stress in rats. This schedule was employed as a model for study of the effects of decompression accidents which may be encountered by human divers.
