Surviving cardiac arrest after carbon monoxide poisoning treated with hyperbaric oxygen therapy

What Researchers Did

Doctors reported a single case of a 31-year-old patient who survived cardiac arrest caused by carbon monoxide and cyanide poisoning after receiving HBOT, despite existing guidelines advising against it in arrest patients.

What They Found

The patient had gone into cardiac arrest from combined carbon monoxide and cyanide poisoning during a fire and required CPR. After HBOT was administered, the patient survived, an outcome that contradicts current UHMS guidelines, which do not recommend HBOT for patients who have required resuscitation.

Canadian Relevance

Carbon monoxide poisoning is an OHIP-covered indication for HBOT in Ontario. However, current guidelines exclude patients who required CPR, and this case does not change that policy, it only questions it.

Study Limitations

This is a single case report and cannot establish whether HBOT caused the survival or whether other factors contributed.
