title: Closed circuit, multiperson, lung-powered rebreathers for hyperbaric oxygen treatment.
abstract: During the conceptual design of a "fly away" Submarine Rescue System (SRS) for the US Navy, a closed circuit breathing system for hyperbaric oxygen treatment was chosen to reduce the weight and volume of the necessary oxygen stores used in decompression treatments. A multiperson, human-powered breathing system was modeled and analyzed for potential development. The potential development of a prototype will allow empirical testing of performance parameters such as breathing, resistance, oxygen concentration, and hyperbaric gas analysis. As a spinoff of the multiperson concept, the modification of commercial off-the-shelf closed circuit air rebreathers are now being considered as an alternative for development. Each concept has benefits and limitations in providing a solution to the procurement of a key component to the SRS.
