Carbon Monoxide Poisoning

Carbon monoxide poisoning occurs when this odorless, colorless gas is breathed in, produced by the incomplete combustion of heaters, stoves, braziers, or engines, and which reduces the blood's ability to carry oxygen.

Warning signs: Headache, dizziness, nausea, weakness, confusion, and drowsiness usually appear; with intense exposure, fainting may occur.

When is it an emergency? If several people or pets in the same enclosed space have these symptoms at the same time, it is best to go outdoors immediately and seek emergency care.

Who treats it? In the acute phase the emergency physician steps in; the general practitioner, the internist, and the pediatrician take part in the assessment and follow-up. If you suspect exposure, going to an emergency department without delay is the safest decision.
