... an increase in plasma HCO 3 – levels, but arterial pH does not change because of a ventilatory compensation that counters the metabolic alkalosis. It seems, therefore, that ventilation is controlled to preserve pH and not P CO 2 during the postprandial period. To investigate this possibility, we determined...
