I've been diving nitrox for a while and read piles of bumf on oxygen toxicity, acute and chronic. Pulmonary exposure seems to be a limiting factor in deco scheduling on extreme technical dives, with various methods of calculating maximum allowable exposure over a dive, series of dives and weeks of dives. I understand that oxygen is potentially damaging to lung tissues and why. However, I had a long conversation with a doctor fried who works in the ITU in Glasgow (asked to remain nameless) who tells me that they regularly have ill patients on pure O2 (realistically 90% due to masks etc) for many days 24hrs a day. No air breaks etc. I asked if this was damaging their lungs and he said sure, a bit, but nothing to worry about and certainly nothing permanent. He laughed, as did a colleague, when I explained the diving line on chronic oxtox. Long term exposures to high F02's seem the norm in hospitals.
Any thoughts?
