APPENDIX D 



TREATMENT SCHEDULE FOR USE IN EMERGENCY OR ACCIDENTAL DECOMPRESSION 

 FROM 100-FSW SATURATION 



1. Recompress diver to 165 FSW in the 

 DDC immediately in an air breath- 

 ing atmosphere. 



2. If full recovery or stabiliza- 

 tion occurs within 15 min, 

 proceed to step 5 herein. 



3. If diver's condition does not 

 stabilize or if it continues 

 on a downhill course, further 

 recompress him to 200 FSW and 

 change breathing mixture to 

 90% He-10% 02- If stabiliza- 

 tion or recovery results from 

 this procedure, proceed to 

 step 5 . 



4. If procedures of step 3 are 

 unavailing in producing stabi- 

 lization or recovery of the 

 diver, further decompress him 

 to 250 FSW and maintain 



90% He-10% O2 breathing mix- 

 ture. 



5 . Keep diver 24 hr at whatever 

 pressure the treatment halted 

 or reversed symptoms. Adjust 

 Op percentage to normoxic value 

 within 4 hr. 



6. Decompress diver to 70 FSW at the 

 rate of 24 min per ft. Maintain 

 the normoxic breathing mixture. 



7. Follow regular 100-FSW decompres- 

 sion schedule from 70 FSW to 

 surface pressure. Switch to air 

 breathing if diver was on N2-O2 

 previously. Otherwise he must 

 remain on the normoxic He-O- mix- 

 ture interspersed with periods 

 of breathing 100% O^ , as indicated 

 in Appendix C .
