Abstract:

Carbon monoxide poisoning or “silent killer” is the most common fatal poisoning, found in very common sources of exposure such as cars, smoking and gas or fuel combustion. The main acute harmful characteristic of gas is based on its high affinity for hemoglobin, while the chronic effects are based on its interaction with other proteins.

Before the nonspecific clinic of the table, must have a high degree of diagnostic suspicion, to start the appropriate treatment or normobaric or hyperbaric oxygen therapy as appropriate.

Key words: Acute intoxication; carbon monoxide; toxic gases; carboxyhemoglobin
