Hyperbaric oxygen treatment of poisoning
Experiments have suggested reduction of neurological sequelae from carbon monoxide (CO) poisoning by treatment with hyperbaric oxygen (HBO). Randomised clinical trials have, however, been ambiguous. The discrepancy may be explained by timing of HBO relative to exposure. For other asphyxiants data are too sparse for a qualified judgement. Until more evidence is available, we suggest that HBO is used exclusively for moderate an d severe CO poisoning within a time window of 12 hours.
