The program office desires an ODMS for use in the PRM, the SDCs, and on the surface. Implementation of O2/air decompression capabilities will reduce decompression time by as much as 25 hours, which will significantly reduce the amount of time DISSUB survivors must remain on the DISSUB awaiting rescue. Biomedical research has identified that delivery of Oxygen (O2) in advance of decompression and decompression via O2/air significantly increases the successful decompression of saturated personnel and significantly decreases the amount of time required to decompress. Navy SRS Decompression Plan and is currently administered using standard air decompression tables, which result in decompression timelines in excess of 57 hours for each able-bodied survivor from 5 Atmospheres Absolute (ATA). The decompression of survivors is accomplished via the U.S. Other properly functioning hyperbaric chambers can be vented to avoid unwanted pressurization. (4) The chamber pressure in the PRM cannot be reduced during transit. (3) Certain methods for monitoring hyperbaric oxygen delivery do not appear to scale to these larger numbers. Compressed oxygen for submarine rescue is limited and may not be replenished during the successful rescue window of opportunity. (2) Shore-based hyperbaric oxygen is typically administered via open circuit because compressed oxygen is easily obtained. ![]() There is no known system for monitoring the oxygen status for 35 individuals in a hyperbaric chamber. (1) Clinical hyperbaric systems support much fewer occupants. There is no known commercially available hyperbaric oxygen delivery and monitoring system capable of handling this many people at sea where compressed oxygen and air are limited. ![]() Each SDC has a maximum capacity of 35 occupants however, only 33 can be seated. The PRM can transport a maximum of 16-seated DISSUB survivors per sortie and two attendants. These mechanisms are joined together by flexible manways that let DISSUB survivors transfer under pressure from the PRM to the DTL and then to the SDC, where they undergo saturation decompression to the surface. OBJECTIVE: Develop an Oxygen Delivery and Monitoring System (ODMS) for the Submarine Rescue and Diving Recompression System that increases the successful decompression of DIStressed SUBmarine (DISSUB) survivors and minimizes the time required for rapid decompression.ĭESCRIPTION: The principal components of the Submarine Rescue System (SRS) Decompression Plan are composed of the Pressurized Rescue Module (PRM), the Deck Transfer Lock (DTL) and two Submarine Decompression Chambers (SDCs).
