Carbon monoxide poisoning symptoms

Published January 03. 2014 05:00PM

People cannot smell, taste, or feel carbon monoxide. Therefore, its presence may not be evident until symptoms develop. Symptoms of carbon monoxide poisoning include:




Rapid heart rate

Irregular breathing

Nausea and/or vomiting

Thought impairment or disorientation

Wheezing/bronchial constriction/pesistent cough

Chest pain in persons with coronary artery disease

Death can occur in the absence of some or all of these symptoms. In this case the victim simply "falls asleep" and never regains consciousness.
