SCOPE Background Methods Results Conclusion
Background US Navy Decompression Practices Followed globally Pioneers Followed globally Recreational Divers Recompression Therapy Technical divers
Methods SALVEX 2011 Indian Clearance Divers in US Deco Practices USNS Salvage INS Nireekshak Off Port Blair: Jan 2011 Indian Clearance Divers in US Deco Practices 42 MSW / 140 FSW Surface Supported Dive in KMB MK 17B

Results Surfaced directly Place in Chamber in 3.5 minutes Recompressed to 40 FSW (~12 MSW) Stoppage of 11 Min @ 40 FSW 1min 20 sec ascent to Surface on O2
Conclusion Advantages of Sur DO2 Shorter exposure in water Hypothermia prevention Decreased Marine Anima Injury Less chance of “Blow up” Safety from Sea conditions Decreased Decompression time Controlled Decompression in chamber
Conclusion Disadvantages of Sur DO2 Application in our set up? Extensive resources Chamber Manpower Oxygen requirements Synchronised timings Increased risk of DCS Application in our set up?
