carbon monoxide poisoning

30

An individual suffers a blood clot in an artery that delivers blood to his leg. The leg begins to take on a blue hue, becomes colder than the rest of his body and he experiences numbness in the leg. He is most likely experiencing-

ischemic hypoxia

An individual has an ideal weight of 125 pounds. Based on this fact, the estimated size of his anatomical (respiratory) dead space is-

125 milliliters

37

The most important factor that determines the percentage of oxygen saturation of hemoglobin is?

Po2
