ABG Interpretation - Alternative Approaches to Acid Base Analysis

Explore alternative approaches to acid-base analysis in this comprehensive 37-minute lecture. Delve into the base excess and Stewart methods, comparing them qualitatively and quantitatively to the traditional approach. Learn about the evolution of acid-base physiology, examining various approaches including the Boston, Copenhagen, and Stewart methods. Understand the concepts of normal gap vs. elevated gap acidosis, and SID vs. SIG acidosis. Analyze simple phenomena like gastric acid secretion using qualitative analysis. Discover algorithms for analyzing acid-base status and gain insights into Stewart's primary acid-base disorders. Conclude with a thorough understanding of these alternative approaches and their applications in medical practice.
