C. The patient’s presentation is concerning for cyanide toxicity, which, although rare, when it does occur is associated with smoke inhalation from residential and commercial fires. Soot in the mouth or nose, altered mental status, hypotension, cherry red color to the skin, inappropriately reassuringly high SaO2 are clues to the diagnosis. Cyanide antidotes include hydroxocobalamin or sodium nitrite and sodium thiosulfate.
