Evaluation of an Acid–Base Disorder

  • Alluru S. ReddiEmail author


In Chap. 26, we stated that a change in plasma [HCO3 ] results in a metabolic acid–base disturbance, whereas a change in arterial pCO2 results in a respiratory acid–base disorder. Clinically, four primary acid–base disorders can be recognized: (1) metabolic acidosis; (2) metabolic alkalosis; (3) respiratory acidosis; and (4) respiratory alkalosis. Values for an arterial blood gas (ABG) for each primary acid–base disorder are shown in Table 27.1.
