Free BCEN Certified Emergency Nurse (CEN) Practice Question
In the treatment of inhalation injuries, administration of 100% oxygen is recommended to displace carbon monoxide from hemoglobin in cases of carbon monoxide poisoning.
In cases of carbon monoxide poisoning secondary to inhalation injuries, it is crucial to administer 100% oxygen. Carbon monoxide binds with hemoglobin more effectively than oxygen, forming carboxyhemoglobin, which inhibits oxygen transport and release throughout the body. Administering 100% oxygen helps displace carbon monoxide from hemoglobin, thereby restoring its oxygen-carrying capacity and alleviating the symptoms of poisoning.
