Health Indicator Report of Emergency Department Visits for Unintentional Carbon Monoxide Poisoning

Carbon monoxide (CO) is a colorless and odorless poisonous gas produced by the incomplete burning of solid, liquid and gaseous fuels. Unintentional CO exposure to people most frequently occurs due to improper ventilation, and or inhalation of exhaust fumes from vehicles, generators, gas furnaces or heaters. CO poisoning can also occur in combination with smoke inhalation and burns during residential fires. While most CO poisoning can be prevented, every year more than 500 Americans die as a result of exposure to this toxic gas. Thousands of Americans annually need to get medical care for non-fatal CO poisonings. Symptoms of CO exposure may include: headache, fatigue, shortness of breath, nausea, dizziness and confusion. At high levels, CO poisoning causes loss of consciousness and death. Survivors of severe poisoning may suffer long-term neurological problems. CO poisoning can be prevented by the installation of CO detectors/alarms and the proper maintenance of heating systems.

How Are We Doing?

Between 2015 and 2019, emergency department visit rates due to unintentional CO poisoning have averaged 0.15 per 100,000 persons from fire-related causes, 5.0 per 100,000 persons from non-fire related causes (e.g. fumes from improperly ventilated heaters, furnaces or motor vehicles) and 1.1 per 100,000 persons from unknown causes per 100,000 persons. Most of the cases are attributable to non-fire-related causes.
