What are the symptoms of carbon monoxide poisoning?

The symptoms of carbon monoxide poisoning include headache, dizziness, weakness, nausea, and confusion. These symptoms occur because carbon monoxide interferes with the body’s ability to transport oxygen. As CO binds to hemoglobin in the blood, it forms carboxyhemoglobin, reducing the amount of oxygen that can be carried to tissues and organs. This can lead to the various symptoms mentioned.

Headaches may occur due to reduced oxygen delivery to the brain, while dizziness and weakness can be a result of insufficient oxygen in the body. Nausea can arise as the body responds to the toxic effects, and confusion indicates a more severe impact on brain function.

Understanding these symptoms is crucial for recognizing carbon monoxide poisoning early, as it can rapidly become life-threatening without prompt intervention. Other options listed, like high fever or rash, are not typical indicators of carbon monoxide exposure. These features highlight why the specified answer accurately identifies the primary and concerning symptoms of this type of poisoning.
