What Researchers Did
Researchers presented two case reports of patients with severe neurological impairment due to carbon monoxide intoxication who received delayed hyperbaric oxygen therapy.
What They Found
Two patients with severe neurological impairment, despite low admission carboxyhaemoglobin levels of 2% and 1.7%, responded well to hyperbaric oxygen therapy. In one of these cases, symptoms recurred several days later but also improved with further hyperbaric oxygen treatment.
Canadian Relevance
This study has no direct Canadian connection as it was conducted in New Zealand.
Study Limitations
As a case study involving only two patients, the findings cannot be generalized to a larger population.
