What is the primary consequence of inhaling carbon monoxide?

The primary consequence of inhaling carbon monoxide is hypoxia, which occurs because carbon monoxide binds with hemoglobin in the blood more effectively than oxygen does. This binding reduces the blood's ability to carry oxygen to the body's tissues and organs, leading to a state where the body is deprived of the oxygen it needs to function properly.

When hypoxia occurs, the body’s cells and tissues do not receive adequate oxygen, which can result in symptoms such as fatigue, dizziness, and impaired judgment. While fatigue and dizziness can occur as secondary effects of hypoxia, they are not the primary consequence. Hyperventilation, which is an increase in breathing rate, may happen in response to a lack of oxygen, but it is not a consequence of inhaling carbon monoxide itself. The critical issue with carbon monoxide exposure is its direct impact on the oxygen-carrying capacity of the blood, leading to hypoxia, which can be life-threatening if not addressed.
