What is the term for elevated carbon dioxide levels in the blood?

Explanation:
Elevated carbon dioxide in the blood is called hypercarbia (also known as hypercapnia). This term specifically describes higher CO2 levels in the blood, regardless of pH. Acidosis refers to a low blood pH and can occur when CO2 is high, but the term asked for is the CO2 elevation itself. The other options describe oxygen status—hypoxemia means low blood oxygen, and hypoxia means inadequate oxygen delivery to tissues. So hypercarbia is the correct term.
