Advanced Technologies for Reducing Decompression Obligation in Extreme Dives

Despite over 100 years of research, decompression sickness (DCS) remains the mission-limiting factor in the design and execution of deep combat dives. Divers may spend over an hour decompressing after spending as little as ten minutes at the target depth. While decompressing, divers are limited in vertical mobility, making then susceptible to detection and threatening their survivability. Recent technological advances in a number of areas may provide the means to limit the need for decompression. The Creare team proposes to develop an Integrated Diver Physiology Platform (IDPP) to reduce the decompression obligation of combat divers in extreme dive profiles. The IDPP will use novel, probabilistic decompression algorithms to change the breathing gas composition in real time to reduce decompression risk, control the delivery of DCS-mitigating pharmacological agents, and prescribe a personalized ascent profile. The algorithms will be supported by an integrated, miniaturized, physiological sensor suite monitoring bubble formation, breathing gas composition, tissue inert gas tension, and other common physiological metrics. This physiological feedback will allow the system to minimize decompression obligation while monitoring and maintaining the safety of the diver, enabling dive profiles currently impossible with existing technologies.
