Transportable Recompression Chamber System (TRCS)

Introduction From Information for Marines web site:

The TRCS is a combination of two pressure vessels used to treat divers suffering from decompression sickness and air embolisms. One vessel, the conically shaped Transportable Recompression Chamber (TRC), is used as the emergency evacuation chamber and for decompressing divers. The Transfer Lock (TL) is designed to transfer people, normally medical personnel, in and out of the TRC. The two vessels, TRC and TL, are connected by a freely rotating NATO flange coupling. The vessels are supported with individual oxygen/air support racks used to supply and control oxygen/air to personnel in the vessels. The TRCS will be transportable by various ground, ship, and air transportation. This will enable a diver to receive prompt medical treatment when located at a remote site.

Characteristics: Recompression Chamber Transport Lock Capacity: 1 Patient 1 Medical Person 1 Medical Person Physical Characteristics for TRC Length 90 in. Width 47 in. Height 49 in. Weight 1,213 lbs. Cube 50 cu. ft.

Unit 3) talk with a "patient" inside a transportable recompression chamber system (TRCS) during Exercise Kernel Blitz '97. These devices are used on divers who are brought to the surface too quickly for the body to properly decompress. The chamber recompresses the diver to a safe depth, and then slowly recompresses to normal pressure. Exercise Kernel Blitz '97. was an exercise near the Southern California coast designed to train U.S. Sailors and Marines and Canadian and Australian troops in amphibious operations.
