ABG Interpretation - The Delta Ratio and Triple Disorders

Dive into the complexities of acid-base balance interpretation with a focus on the Delta Ratio and Triple Disorders. Learn how to utilize the delta ratio (also known as the "delta-delta") and the delta gap to diagnose mixed metabolic disorders, including triple acid-base disorders. Explore the concept of the Expected Delta Ratio and its application in identifying elevated gap metabolic acidosis and metabolic alkalosis. Examine the Delta Gap, its limitations, and work through practical examples involving lactic acidosis, ketoacidosis, and triple acidemia. By the end of this 21-minute lesson, gain a comprehensive understanding of these advanced ABG interpretation techniques, enhancing your ability to diagnose complex acid-base imbalances in clinical settings.
