1. NAVY EXPERIMENTAL DIVING UNIT (NEDU) IS SEEKING VOLUNTEER ACTIVE DUTY OR RESERVE U.S. NAVY 2ND CLASS AND ABOVE QUALIFIED DIVERS TO PARTICIPATE IN EXPERIMENTAL AIR DECOMPRESSION DIVES IN THE NEDU OCEAN SIMULATION FACILITY IN PANAMA CITY, FL, DURING THE FOLLOWING DATES:

A. 21MAR-14APR06 (8 DIVERS)
B. 07AUG-01SEP06 (12 DIVERS)
C. 02OCT - 01DEC06 (12 DIVERS)

ALL DIVING IS DONE MONDAY - THURSDAY, WITH DIVING ON FRIDAYS POSSIBLE IF NECESSARY. THE DIVES ARE BEING CONDUCTED UNDER NEDU INSTITUTIONAL REVIEW BOARD-APPROVED PROTOCOL NEDU 05-23/32174 (REFA) TO TEST THE EFFICACIES OF ALTERNATIVE DISTRIBUTIONS OF EQUAL 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 WEAR T-SHIRT AND SWIM TRUNKS WHILE FULLY IMMERSED IN 86°F (30°C) 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.

4. TRAVEL AND LODGING (NAVAL SUPPORT ACTIVITY PANAMA CITY, FL BEQ) COSTS FOR VOLUNTEERS WILL BE COVERED BY NEDU. VOLUNTEERS WILL RECEIVE THE STANDARD AREA PER DIEM ALLOWANCE. HAZARDOUS DUTY INCENTIVE PAY IS AUTHORIZED FOR THESE DIVES.

5. VOLUNTEERS MUST HAVE A CURRENT DIVING PHYSICAL. IN ORDER TO REVIEW RECORD PRIOR TO REPORTING, VOLUNTEERS WILL BE REQUIRED TO FAX A COPY OF CURRENT DIVE PHYSICAL PRIOR TO REPORTING AND PROVIDE ACTUAL MEDICAL RECORD UPON REPORT TO NEDU. NEDU MEDICAL STAFF WILL BE FINAL DETERMINING AUTHORITY ON MEDICAL QUALIFICATION TO DIVE. IT IS IMPERATIVE THAT ALL VOLUNTEERS BE MEDICALLY QUALIFIED, IN WRITING, COMPLYING WITH ALL CURRENT DIRECTIVES, OR HAVE APPROVED WAIVERS FOR NON-CONFORMANCES. IF DMOS HAVE ANY QUESTIONS, NEDU POC IS LT HILL AT 850-230-3199.

6. VOLUNTEERS WILL BE REQUIRED TO READ AND SIGN AN INFORMED CONSENT FORM AND MUST SUCCESSFULLY COMPLETE A PRELIMINARY MEDICAL SCREENING EXAM AT NEDU BEFORE THEIR FIRST DIVE. VOLUNTEERS WILL REMAIN AT NEDU FOR A MINIMUM OF 9 CONSECUTIVE DAYS; ARRIVING BEFORE 2100 ON A FRIDAY WITH EARLIEST DEPARTURE AFTER 1300 ON THE FOLLOWING SATURDAY. VOLUNTEERS WILL PARTICIPATE IN TWO DIVES DURING THIS PERIOD AND MUST OBSERVE ALL OTHER PROSCRIPTIONS IN THE PROTOCOL, INCLUDING:

A. NO FLYING OR OTHER DIVING WITHIN THE PERIOD OF PARTICIPATION;
B. REMAIN WITHIN 30-MIN TRAVEL TIME OF NEDU FOR 24-HR AFTER EACH dfDIVE;

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 MODEL TO BE USED TO CREATE THE NEW USN DIVE TABLES. YOU CAN BE PART OF THIS!
