Utility of High Flow Nasal Cannula in CO Toxicity

"A high flow nasal cannula will be implemented to the CO-poisoned patients. In the meantime, intravenous access and cardiac monitorization will have been establishing. When the high flow nasal cannula becomes ready, the first venous blood sample will be taken and the treatment will be started without any delay. The gas flow rate will be started at the rate of 30 liters per minute and will be increased to the max flow rate which patient can tolerate and FiO2 of 1.0. If the first COHb level is lesser than 10%, the patient will be excluded and will receive standard emergency care.~The blood sample will be drawn from existing IV access every 10 minutes until the COHb levels become %50 or lesser of the initial level.~Once the COHb level becomes 50% of initial measurement, following blood samples will be taken in every 30 minutes."
