Four Basic Therapy Options
Recompression Chamber on Site
In-water Recompression Therapy
Oxygen Therapy during Transportation
Oxygen Therapy Without Recompression
RECOMPRESSION CHAMBER ONSITERepresentative Examples
Hydrogen Bomb Search, Mediterranean Sea 150’-165’ Surface Supplied Air
U. S. Navy 1966 Biological Research Studies, Gulf of Maine, USA
105’ – 120’ Open-Circuit Scuba NOAA/NMFS 1977
Archaeological Research, Mediterranean Sea 100’-200’ Open-Circuit Scuba

Metal ChambersSuccessfully Used For Recompression Therapy Onsite
Single-occupant Chambers and Dual-occupant Chambers
Older, Single Occupant “Coffin Chamber”

Multi-place and Multi-lock Chambers
Major Considerations
Size and Weight
42 inch diameter double-lock recompression chamberLess than ~3000 lbs (~1315 kg)
Vortex
Tube
Cooling
Eclipse Oxygen
Generator
Required Equipment Extra To Research Diving Operations
Without RecompressionCapabilities
Recompression Chamber
Vortex Cooling Tube
Oxygen Generator
Semi-closed Rebreather Inside the chamber
Addition of Chamber and Associated Equipment Means
Increased Safetye. g. Onsite Diving Accident Management
Increased Efficiencye. g. Surface Decompression with Oxygen
Increased Safety plus Increased Efficiency Equals
Increased Cost Effectiveness
