For those who do not know, a typical Table 6 treatment can be up to 6 hours long. At a SAC of .5 cuft/min one would need about 360 cu/ft of O2 at 30 feet. Depending on the severity depths may start at 60 feet on pure O2 thus requiring yet more gas. Obviously an injured diver could likely consume 4 times that amount. That's roughly 19 alu 80's of pure O2 at 3000 psi as gas for the injured diver only.
Even forgetting the risk of ox-tox and drowning, dehydration, hypothermia, etc, that's a fair amount of gas that has to make it down to the diver. And the treatment will only work if it's completed. And a bad bend can take SEVERAL table 6's over many days, plus hospital time, and dive physician supervision, to fix. Logistically that's a pretty hard thing to accomplish.
That's why the frequent and near-universal "do not attempt" caveat for IWR.
All numbers are approx and for illustrative purporses only. Do not attempt IWR at home or abroad. I may be a doctor, but not that kind. I'll have a look anyway ;-)
