title: Acid-base disorders: classification and management strategies.
abstract: Acid-base disorders are common in clinical practice. Simple acid-base disturbances include metabolic acidosis, metabolic alkalosis, respiratory acidosis and respiratory alkalosis. Each can be clearly identified using a common clinical approach. Proper understanding of acid-base disorders requires knowledge of normal physiology. Each of the simple acid-base disorders can be diagnosed by obtaining a good history and performing a physical examination, followed by determinations of electrolyte levels, anion gap and pH. The degree and nature of compensation should then be analyzed. Finally, the ratio of the change in anion gap to the change in serum bicarbonate (delta AG/delta HCO3-) should be determined. When this diagnostic process is applied, proper identification of the disorder can be made and management can be undertaken. Mixed acid-base disorders can also be identified and managed using this method.
