And, those logistics raise an interesting question. Is the patient better off with the maximum gradient for as long as possible, or a reduced gradient for a longer period of time? I can see arguments both ways.
You mean from a decompression point of view? That's what decompression algorithms and recompression tables do - optimize offgassing. DDM can give you the real answer, but if you are talking about a patient with DCS, then the standard treatment (e.g. Navy table 6) involves O2 and air segments at standard pressures. It's not just a question of 100% O2 for as long as possible...
