Description #
In this lecture we will explore how the body regulates levels of pH in the blood. We will consider disturbances of [H ] concentration and the causes of the four primary acid-base disorders. We will discover how to assess acid-base status from blood gas data sets, and assess for appropriate compensation. We will look at normal values of [H ], volatile and fixed acids and the elimination of acid. Next, we discuss major buffer systems in the blood, Henderson-Hasselbalch equation, blood gas measurements and blood gas analyzers. Finally, we will look at acid-base disturbances, compensation for an abnormal pH, Anion gaps, metabolic acidosis and metabolic alkalosis, and respiratory acidosis and respiratory alkalosis.
Learning Objectives #
• Identify acid-base disorders from blood gas data
• List causes of an abnormal anion gap
• Develop a differential diagnosis for each of the acid-base disorders
