Net acid excretion


In renal physiology, net acid excretion is the net amount of acid excreted in the urine per unit time. Its value depends on urine flow rate, urine acid concentration, and the concentration of bicarbonate in the urine. NAE is commonly expressed in units of milliliters per minute and is given by the following equation:

Pathology

Increased net acid excretion is a compensation for respiratory acidosis, while decreased net acid excretion is a compensation for respiratory alkalosis.
