What are the signs and symptoms of carbon monoxide poisoning?

The signs and symptoms of carbon monoxide poisoning are primarily related to the way carbon monoxide affects the body's ability to deliver oxygen to tissues. When inhaled, carbon monoxide binds to hemoglobin in the blood more efficiently than oxygen, leading to reduced oxygen supply to the body's organs and tissues.

Headache, dizziness, weakness, nausea, and confusion are classic symptoms associated with this type of poisoning. These symptoms can occur because the brain and other vital organs are not receiving adequate oxygen. Headaches are common due to the lack of oxygen, while dizziness and weakness can occur due to general hypoxia. Nausea and confusion are also prevalent as the body struggles to cope with the stress of reduced oxygen levels.

In contrast, the other options list symptoms that are not typical indicators of carbon monoxide exposure. For instance, dry skin and muscle cramps are more associated with dehydration or electrolyte imbalances rather than carbon monoxide poisoning. Similarly, elevated heart rate and visual disturbances, while they may occur in some medical conditions, are not specific to carbon monoxide poisoning. Lastly, chest pain, shortness of breath, and fever might indicate respiratory or cardiac issues but are not direct symptoms of carbon monoxide exposure. Thus, recognizing the correct symptoms is crucial for timely diagnosis and treatment of carbon
