How should EMS respond to suspected cyanide poisoning in a fire victim?

• A. Provide 100% oxygen, assist ventilation as needed, monitor for deterioration, rapidly transport, and initiate antidote protocols if available
• B. Ignore symptoms and wait
• C. Administer nitroglycerin
• D. Transport without oxygen

Answer: (A)

The main idea is that suspected cyanide poisoning from a fire requires immediate actions to maximize oxygen delivery and prepare for antidote therapy as quickly as possible. Cyanide prevents cells from using oxygen, so providing 100% oxygen and supporting ventilation helps reduce tissue hypoxia even though the toxin blocks cellular respiration. Rapid transport is essential because definitive antidote treatment and advanced care are typically available in hospitals. If antidotes are available in the field and your protocol allows, administer them promptly. In addition, continuously monitor for deterioration and manage the airway and breathing as needed. Fires often involve exposure to both cyanide and carbon monoxide, so high-flow oxygen also helps address CO toxicity. The other options don’t fit: ignoring symptoms delays lifesaving care, nitroglycerin has no role here and can be harmful, and transporting without oxygen would neglect a critical need.
