Elimination of carboxyhemoglobin with various oxygen therapies. (a) Theoretical elimination of carboxyhemoglobin (COHb) after removal from source and given hyperbaric oxygen (HBO) versus other oxygen therapies. (b) Elimination of COHb after removal from the source, receiving high-flow oxygen and following a typical delay of 2Â hours to be given HBO versus other oxygen therapies. ATM, standard atmospheres; O2, oxygen.
