What Researchers Did
Researchers reported on a 90-year-old man who experienced repeated unconsciousness due to chronic carbon monoxide poisoning from a briquette kotatsu.
What They Found
A 90-year-old man presented with impaired consciousness and a carboxyhemoglobin level of 18.0% due to chronic carbon monoxide poisoning. He received high-flow oxygen therapy, which quickly improved his condition. The study noted that high-flow oxygen therapy may be sufficient for carbon monoxide poisoning, even in places without hyperbaric oxygen therapy.
Canadian Relevance
This study covers carbon monoxide poisoning, which is a Health Canada-recognised indication for hyperbaric oxygen therapy.
Study Limitations
As a single case report, the findings may not apply to all patients with chronic carbon monoxide poisoning.
