Question

Quizplus · Accepted Answer

$\mathrm { P } _ { 0 _ { 2 } }$ refers to the partial pressure of oxygen in the blood, which is the pressure exerted by the amount of oxygen dissolved in the blood. It is a crucial factor in determining the percent saturation of hemoglobin. In carbon monoxide poisoning, $\mathrm { P } _ { 0 _ { 2 } }$ remains normal because carbon monoxide affects hemoglobin's ability to bind oxygen, not the amount of oxygen dissolved in the blood.
