An increase in the H⁺ ion concentration [H⁺] of the blood due only to an increase in the arterial PCO₂ (hypercapnia) best describes which of the following?

Question

Quizplus · Accepted Answer

For example, if the pH was lower than 7.35 (denoting an acidosis) and the PaCO₂ was higher than 45 mm Hg, according to the H-H equation, the high PaCO₂ would indeed lower the pH (i.e., produce an acidosis). Therefore, the respiratory system is at least in part, if not entirely, responsible for the acidosis.
