For adult cyanide exposure, what is the recommended oxygen delivery method?

• A. O2 via NRB at 15 L/min
• B. Cyanokit: 5 g IV/IO over 10-15 minutes
• C. Administer 100% oxygen via bag-mask ventilation only
• D. Do not administer oxygen

Answer: (A)

When cyanide blocks cells from using oxygen, the goal is to maximize the amount of oxygen carried in the blood to improve overall tissue oxygen delivery. Delivering high-concentration oxygen through a non-rebreather mask at about 15 L/min achieves the highest feasible FiO2 in a non-intubated patient, making it the best initial oxygen strategy. While bag-mask ventilation can also provide 100% oxygen, it’s primarily used during airway management or resuscitation and isn’t the most practical stand-alone method for ongoing oxygen delivery. Oxygen is important, but so is definitive antidotal treatment (such as cyanide antidotes) to address the underlying toxicity. Do not withhold oxygen.
