Massachusetts Medical Society: Carbon Monoxide Poisoning

Carbon Monoxide Poisoning

Carbon Monoxide Poisoning Course

Carbon monoxide (CO) poisoning, both acute and chronic, can be difficult to diagnose and mimic other conditions.  In a study of children presenting to the emergency department with afebrile viral symptoms who were found on exposure history to have a potential source of CO exposure, 50% of the children had elevated carboxyhemoglobin (COHb) levels.  There are also case reports of emergency medical service personnel becoming victims themselves of CO poisoning by not recognizing a potential exposure. This activity promotes awareness of the risks and symptoms of carbon monoxide poisoning, and is designed to promote understanding of best practices related to diagnosis, treatment and prevention of carbon monoxide poisoning. 

Learning Objectives

  • Examine the current epidemiology of carbon monoxide poisoning by learning the etiology and historical context of carbon monoxide.

  • Discuss classic and contemporary sources of carbon monoxide and the breadth of possible presentations of carbon monoxide poisoning.

  • Interpret laboratory COHb levels and be familiar with the benefits and limitations of non-invasive COHb detection.

  • Recognize goals of oxygen therapy for the treatment of carbon monoxide poisoning as well as the risks/benefits of hyperbaric oxygen therapy.

  • Incorporate pediatric-specific considerations into the treatment of carbon monoxide poisoning.    


Theodore Eric Macnow, MD is a pediatric emergency fellow at Boston Children's Hospital.  Dr. Macnow graduated from Tufts University School of Medicine in 2009.
