Adapting the Ohmeda UPAC draw-over vaporizer for use in the modern operating room

Until recently, the use of draw-over anesthesia (DA) for elective cases has been prohibited in American military hospitals. The reasons cited for this have included the possibility of increased patient risk and the delivery of a second level of care. In this article, the authors outline a method of employing DA so as to bring its use up to the safety level of the modern operating room. This allows for the clinical training of those military anesthesia care providers who may find themselves deployed with highly mobile surgical units whose missions demand this technique of anesthesia.
