A CO2 level above 45 mmHg is associated with which state?

Explanation:
High CO2 in the blood lowers pH because CO2 combines with water to form carbonic acid, which dissociates to release hydrogen ions. When the partial pressure of CO2 is above 45 mmHg, more carbonic acid builds up, pH drops, and the body is in an acidosis state. This is known as respiratory acidosis, which can occur with hypoventilation as a contributing cause, but the resulting state described by the question is acidosis. Normal CO2 is roughly in the mid-30s to mid-40s; alkalosis would require CO2 to be low, and normal would not involve elevated CO2.
