Scope
SCOPE

  • Background

  • Overview of the Problems of the Trial Directive

  • Proposed Objective of the Trials

  • Limitations of the Trial

  • Diving Issues & solutions

  • Medical Aspects & solutions

  • Conclusion


Background
Background

  • Submarine Escape Suit (SES)

    • “Wet escape”: Exposure to the ambient pressure

    • Provide “breathable” pressurised gas mixture

      • Hypoxia

      • Oxygen Toxicity

    • Choice of “diluent gas”

      • Minimise chance of DCS & Inert Gas Narcosis

    • Controlled Ascent Rate

      • Reduce risk of barotrauma & CAGE

    • “Survival at Sea” aspects


Background1
Background

  • Currently Used: IDA 59M

    • Soviet origin

    • Mechanical model

    • Provides “Trimix”: 25% O2 + 15%He + 60% N2

    • Varying amounts of Oxygen according to depth

      • ↓ O2: Reduces chances of O2 toxicity at depth

      • ↑ O2: Reduces chances of DCS at shallow depths & surface

  • Indigenous SES

    • Reverse engineered by DRDO

  • SMHQ: Need felt for “Human Trials” to 100MSW


Problems of the trial directive overview
Problems of the Trial DirectiveOverview

  • Mimicking Submarine Escape

  • Control on IDA 59M

  • Compression & Decompression Rates

  • Submarine Escape Tables

  • Objective monitoring of Parameters


Proposed objectives of the trial
Proposed Objectives of the Trial

  • Partial Pressure of Oxygen

  • Partial Pressure of Nitrogen

  • Partial Pressure of Carbon Dioxide

  • Psychological Aspects

  • Endurance of the set


Limitations of the trial
Limitations of the Trial

  • No remark on the individual set

  • Thermal insulation offered by the set

  • Pressure endurance of the materials of the set

  • Survival at Sea aspects


Diving issues and solutions
Diving Issues and Solutions

  • Classification as Experimental Dive

  • Rate of Compression

  • Decompression Schedule

  • Endurance of the Set


Medical issues and solutions
Medical issues and Solutions

  • Illnesses due to breathing gas abnormalities

    • Hypoxia

    • Hyperoxia

    • Carbon Dioxide Toxicity

  • Illnesses due to Inert Gas

    • Inert Gas Narcosis

    • High Pressure Neurological Syndrome


Medical issues and solutions1
Medical Issues and Solutions

Decompression Sickness

  • Preventive Strategies

    • Slow rate of Decompression

    • High Vann K factor

    • High Partial Pressure of Oxygen

    • Selection of Personnel


Medical issues and solutions2
Medical Issues and Solutions

Decompression Sickness

  • Therapeutic strategies

    • Type I DCS post dive

    • Type II DCS post dive

    • DCS during the course of the dive

      Barotraumas

      Not Dive Related (NDR) Illnesses

      Psychological issues


Conclusion
Conclusion

  • Most complex human trial attempted in the Navy

  • Multiple spin offs
