The red curve in the graph below shows O₂saturation in normal conditions and the blue curve to the right shows O₂saturation in someone with carbon monoxide poisoning. You can determine from this curve that carbon monoxide:

Question

Quizplus · Accepted Answer

The saturation level of O₂ in someone with carbon monoxide poisoning is significantly lower than the saturation level in normal conditions. This indicates that carbon monoxide is affecting the ability of O₂ to bind to hemoglobin, which reduces the amount of hemoglobin available to transport oxygen. Therefore, the correct choice is C – carbon monoxide decreases the amount of O₂ that can bind to hemoglobin.
