The ambulance hands over a house-fire victim pulled unconscious from an enclosed space. Clothes smell of smoke, soot rings the nostrils, and there are patchy facial burns. The finger-probe SpO2 reads 99 percent on oxygen. The trap is false reassurance — that number can be a lie.[1]
Smoke inhalation kills by progressive airway oedema, carbon monoxide, cyanide, chemical pneumonitis, and later pneumonia. The viva pivots are crisp: when to intubate, why the pulse oximeter lies in carbon monoxide, the exact half-life numbers, and hydroxocobalamin 5 g IV.[1]
