TOTAL DECOMPRESSION TIMES AMONG STOPS AT DIFFERENT DEPTHS. THE

STUDY IS SUPPORTING DEVELOPMENT OF NEW U.S. NAVY AIR DECOMPRESSION

TABLES AND PROCEDURES, BUT IS ALSO RELEVANT TO MIXED GAS NITROX

(N2-O2) AND HELIOX (HE-O2) DIVING PROCEDURES.

2. ALL DIVES ARE SQUARE DIVES TO 170 FSW FOR 30 MINUTES WITH 180

MINUTES OF DECOMPRESSION UTILIZING THE MK-20 FULL FACE MASK. DIVERS

WATER THROUGHOUT EACH DIVE. DIVERS PERFORM MODERATE EXERCISE ON

BOTTOM AND REMAIN AT REST DURING DECOMPRESSION. DESCENT RATE IS 60

FPM, WITH A SMALL MARGIN FOR HOLDS IF NECESSARY FOR CLEARING. IT IS

IMPERATIVE THAT VOLUNTEERS BE ABLE TO CLEAR.

3. THE RISKS OF DECOMPRESSION SICKNESS (DCS) FROM THESE DIVES ARE

ESTIMATED TO BE BETWEEN 3% AND 6%. TO DATE, 189 MAN-DIVES HAVE BEEN

COMPLETED WITH 8 CASES OF DCS, ALL OF WHICH WERE TREATED IN THE NEDU

TREATMENT CHAMBER WITH COMPLETE RESOLUTION OF SYMPTOMS.

7. NAVSEA 00C STRONGLY SUPPORTS FLEET PARTICIPATION IN THIS

CUTTING-EDGE DIVING PROTOCOL. DATA ACCUMULATED FROM THIS STUDY WILL

HAVE A PROFOUND EFFECT ON NAVY DIVING IN THE FUTURE - THE GREATER

FLEET PARTICIPATION, THE BETTER THE RESULTS WILL BE TO DEFINE THE
