What do cherry red mucous membranes indicate?

Explanation:
Cherry red mucous membranes point to carbon monoxide poisoning. When carbon monoxide is inhaled, it binds to hemoglobin to form carboxyhemoglobin, which is a bright red form of blood. This gives the blood, and thus the mucous membranes, a vivid red color. It’s different from anemia, which makes membranes pale; dehydration can cause dryness, not a bright red color; jaundice causes yellowing. If you see cherry red membranes (especially after exposure to exhaust, fires in enclosed spaces, or smoke), act quickly: move the animal to fresh air, seek veterinary care urgently, and provide oxygen if you’re able to.
