PPT-Acidosis and alkalosis Acid-base disorders are very common clinical problems.

PH 735745 Acidemia is a pH lt735 and alkalemia is a pH gt745 Acidosis and alkalosis are used to describe how the pH changes The primary causes of acidbase disturbances are abnormalities in the respiratory system and in the metabolic or renal system.
