I'm reading the ending of The Last Dive by Bernie Chowdhury, and it involves a diver being placed in a hyperbaric chamber at the equivalent of 60ft, then later 165ft. The diver had come up abruptly from 230ft. My question is, why wouldn't you start out by placing the diver in 230ft (or the lowest the chamber can go - in this case, the 165ft mentioned) instead of starting out at 60ft? Wouldn't you want the nitrogen bubbles in the blood stream to shrink as quickly as possible? Or is there some other physiological issue I'm not considering that makes this a bad plan? (Or maybe, is a hyperbaric chamber different at all from diving at that depth/pressure?)
