WebA decrease in pH is sensed by arterial chemoreceptors and leads to increases in tidal volume or respiratory rate; CO 2 is exhaled and blood pH increases. In contrast to chemical buffering, which is immediate, pulmonary regulation occurs over minutes to hours. It is about 50 to 75% effective and does not completely normalize pH. Webbuffer range. The buffer capacity is the amount of acid or base that can be added before the pH begins to change significantly. It can be also defined as the quantity of strong acid or base that must be added to change the pH of one liter of solution by one pH unit.
