Carbon Monoxide Poisoning

Carbon monoxide (CO) is an odorless, colorless, poisonous gas that can cause sudden illness and death if present in sufficient concentration in the ambient air.

Sources: Carbon monoxide is found in combustion fumes produced by generators, Automobile/ RV, Boat, Kerosene/ gas space heater, power tools (include mover), fuel burning appliances (fixed stove/ boiler/ furnace), portable fuel burning grill/ stove, charcoal grills and fire, etc.

Health Effects: The clinical presentation of acute carbon monoxide (CO) poisoning varies depending on the duration and magnitude of exposure. The most common signs and symptoms include headache, nausea, lethargy (or fatigue), weakness, abdominal discomfort/pain, confusion, and dizziness. Other signs and symptoms may include visual disturbances including blurred vision, numbness and tingling, ataxia, irritability, agitation, chest pain, dyspnea (shortness of breath), palpitations, seizures, and loss of consciousness.

Laboratory Tests: Blood carboxyhemogolbin (COHb) level is useful in confirming the diagnosis of carbon monoxide poisoning. Environmental monitoring data collected by first responders is also useful in the detection of CO exposure.
