Julian,
I recall an article from one of the Medical International magazines some
years ago - it was a review and I don't know the original source - which
gave the half-life of carboxyhaemoglobin as c. 4 hours when breathing room
air; c. 80 mins in 100% O2 and c. 22 mins with hyperbaric oxygen.
I've since seen some case reports etc which seemed to support these figures
but can't say how evidence based they are.

Subject: CO-haemoglobin: help please
