The presence of elevated carbon dioxide levels in the blood is called.

Explanation:
Elevated carbon dioxide in the blood is called hypercarbia, or hypercapnia. This term specifically refers to the amount of CO2 present, which rises when ventilation is inadequate or gas exchange is impaired. While high CO2 often leads to respiratory acidosis because CO2 forms carbonic acid and lowers pH, the focus here is on the CO2 level itself. The other terms describe different problems: hypoxemia means low arterial oxygen, which can cause tissue hypoxia; hypoxia refers to insufficient oxygen delivery to tissues; acidosis is a low blood pH state that can result from various respiratory or metabolic disturbances, not just elevated CO2.
