What Researchers Did
Emergency physicians reported a case of severe carbon monoxide poisoning in a 37-year-old male found unresponsive after hookah smoking, with a carboxyhemoglobin level of 24.9%, treated with HBOT and intensive care.
What They Found
The patient was extubated the following day after HBOT with normalization of carboxyhemoglobin levels and improvement in mental status. The case highlights that hookah charcoal produces high CO levels and that standard pulse oximetry fails to detect CO toxicity -- only a blood carboxyhemoglobin test reveals it.
Canadian Relevance
Carbon monoxide poisoning is an OHIP-covered indication for HBOT in Ontario. The growing popularity of hookah cafes in Canadian cities makes this presentation increasingly relevant to emergency departments.
Study Limitations
Single case report; individual cases do not establish treatment efficacy across the spectrum of CO poisoning severity.
