What Researchers Did
Researchers conducted an online survey of 76 medical institutions in Japan to identify differences in how they treat carbon monoxide poisoning, including the use of hyperbaric oxygen therapy.
What They Found
Of the 48 institutions that responded, 33 (69%) administered hyperbaric oxygen therapy for carbon monoxide poisoning. The main reasons for using HBOT were consciousness disturbance, long exposure to carbon monoxide, and elevated carboxyhemoglobin levels. Treatment pressures varied, with 19 institutions (58%) using 2.0 ATA, 6 (18%) using 2.5 ATA, and 8 (24%) using 2.8 ATA. The number of HBOT sessions ranged from 1-3 on the first day and 1-7 on days 2-7.
What This Means for Canadian Patients
This study shows that treatment practices for carbon monoxide poisoning, including hyperbaric oxygen therapy protocols, can vary between facilities. Canadian patients should know that HBOT is a Health Canada-recognized treatment for carbon monoxide poisoning. It is important for patients to discuss specific treatment options and expected protocols with their healthcare providers.
Canadian Relevance
This study is not Canadian. However, it covers carbon monoxide poisoning, which is a Health Canada-recognized indication for hyperbaric oxygen therapy.
Study Limitations
As a retrospective survey, this study relied on self-reported data from a limited number of institutions, which may not fully represent all practices in Japan.
