What are common symptoms of carbon monoxide poisoning?

The symptoms of carbon monoxide poisoning include fainting, headache, and nausea, which are the most common manifestations of this dangerous condition. When carbon monoxide enters the body, it binds to hemoglobin in red blood cells more effectively than oxygen does, leading to a decrease in the amount of oxygen that is transported in the bloodstream. This insufficient oxygen supply to the body's tissues can result in headache, dizziness, and a feeling of nausea.

Fainting can occur because the brain is particularly sensitive to a lack of oxygen. As the concentration of carbon monoxide increases in the blood, these symptoms may worsen, potentially leading to unconsciousness. Understanding these symptoms is crucial, as early recognition and prompt treatment are essential to prevent serious health complications, including death.

In contrast, the other options do not accurately reflect the primary symptoms associated with carbon monoxide poisoning. Increased blood pressure, rapid heartbeat, sweating, severe skin rashes, and fever are more indicative of other medical conditions and not necessarily primary symptoms of carbon monoxide exposure.
