Changes in pH and their interpretation
Due to the compensating mechanisms of the buffers, lungs and kidneys any primary alteration in the value of either component of the [HCO 3 − ] [H2CO3] ratio invokes a compensatory change in the other component, thus reducing the extent of the initial change in the pH. For example, in a respiratory acidosis with a PCO2 of 80 mmHg (10.6 kPa), if there were no compensatory rise in HCO 3 − , the pH would be 7.1; in other words
