Carbon Monoxide and Asthma

Overview

Asthma is a chronic inflammatory disease of the airways. Carbon monoxide (CO) can have negative effects on asthma and respiratory health. Exposure to high levels of CO can trigger asthma symptoms and exacerbate respiratory conditions. Here's what you need to know about how carbon monoxide affects asthma, how people get exposed to it, and what can be done to reduce exposure:

Carbon monoxide may worsen asthma symptoms by reducing the amount of oxygen available to the body.
Studies have found the people with higher severity asthma symptoms have increased exhaled CO levels.

How People Get Exposed to Carbon Monoxide

Carbon monoxide is a pollutant gas that is released outdoors and contributes to air pollution.
Inhaling large amounts of CO can be toxic and dangerous to human health. CO binds to hemoglobin in blood, which reduces the amount of oxygen that can be carried in blood.
Sources of carbon monoxide include car exhaust, industrial emissions, tobacco smoke, faulty heating systems, and poorly ventilated appliances (such as gas stoves or furnaces).
People can be exposed to carbon monoxide indoors or outdoors, depending on the sources present in their environment.

Preventive Measures for Reducing Exposure to Carbon Monoxide

Ensure proper ventilation in your home by opening windows or using exhaust fans when using gas appliances.
Regularly inspect and maintain heating systems, chimneys, and appliances that use fuel combustion.
Install carbon monoxide detectors in your home as an early warning system for high levels of CO.
Avoid running vehicles or gas-powered equipment in enclosed spaces like garages.
Quit smoking and avoid secondhand smoke exposure.

Remember, if you have concerns about carbon monoxide exposure or its effects on your asthma or respiratory health, it's important to consult with your healthcare provider. They can provide personalized advice based on your specific situation.
