7. Results Surfaced directly Place in Chamber in 3.5 minutes
Recompressed to 40 FSW (~12 MSW)
Stoppage of FSW
1min 20 sec ascent to Surface on O2

8. 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

9. 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?
