I have been reading the book Fatal Depth about the Andrea Doria and all the people that have died diving it.
In the book there is a story about a guy that freaked out and shot to the surface from 250 ft. The book states the captain "ran some software" to determine that the diver needed to descend for four hours to decompress. With the remote location, I guess this is the only option, since a helicopter ride would be 2 hours to the nearest chamber.
My question is what would this look like? What depth(s) would he/she need to descend to and what gasses would he/she need to breath? The book seems to indicate the average decompression time was about 1 hour, so why 4?
The only technical information it provides is the diver was diving a trimix and it was the second dive of the day. The book also indicates its about a 4 hour interval between dives.
Thanks,
Jerrod
