The most important factor that determines the percent of oxygen saturation of hemoglobin is
erik [133]

Answer:

This question lacks options, options are:

a) The partial pressure of oxygen

b) Acidity

c) The partial pressure of carbon dioxide

d) Temperature

e) BPG

The correct answer is a. The most important factor that determines the percent of oxygen saturation of hemoglobin is <u>The partial pressure of oxygen </u>.

Explanation:

Hemoglobin is an oxygen transport protein. Partial Oxygen Pressure (PaO2), measures the pressure of dissolved oxygen in the blood, that is, it shows how well oxygen passes from the lungs into the bloodstream. A high partial pressure of oxygen in the blood produces an almost complete saturation of hemoglobin, which indicates the maximum amount of oxygen that combines, but when PaO2 is reduced, so is hemoglobin saturation, when saturation is below 90% hypoxemia occurs, that is, the level below normal blood oxygen levels.
