In the Core Curriculum entitled “Respiratory Acidosis and Respiratory Alkalosis: Core Curriculum 2023” that appeared in the September 2023 issue of AJKD,1 Figure 4 contained an error in the depiction of the mechanism of chronic respiratory alkalosis. In particular, an arrow indicating the change in Na+/H+ antiporter and Na+/3HCO3− cotransporter was in error: Na+/H+ antiporter and Na+/3HCO3− cotransporter should have been depicted as decreasing, not as increasing. The text describing the mechanism is correct as published.
