The most effective method for improving the oxygenation status of a fireman who has been knocked unconscious in a burning environment is hyperbaric oxygen therapy. This treatment involves placing the patient in a hyperbaric chamber where they breathe 100% oxygen at pressures greater than atmospheric pressure. This approach significantly increases the amount of oxygen dissolved in the plasma and enhances the diffusion of oxygen into tissues, particularly in cases of carbon monoxide poisoning, which is a common risk for individuals exposed to smoke and combustion products.

Hyperbaric oxygen therapy can help displace carbon monoxide from hemoglobin, reducing the symptoms and potential neurological damage associated with carbon monoxide exposure. Additionally, the increased pressure can aid in the healing of tissues that may have been affected by hypoxic conditions during the incident.

Other options, while they may have their roles in clinical settings, do not directly address the acute need to enhance oxygenation in this specific context. Using a non-rebreather mask at a high fraction of inspired oxygen may improve oxygen delivery to some extent, but it is unlikely to match the efficacy of hyperbaric therapy in cases of significant carbon monoxide exposure. Blood transfusion is generally indicated in severe anemia and would not enhance oxygenation in the absence of that condition. Monitoring co-ox
