The Anion Gap & Why it Still Matters - On Demand 2025
ABGs mislead when context is missing; the anion gap still points to the truth. In this on-demand session, you will describe core acid-base physiology, then analyze real cases to interpret simple and mixed disorders. You'll calculate anion gaps and delta ratios, and assess respiratory and metabolic compensation to synthesize a full picture. By the end, you can confidently apply a systematic approach that sharpens bedside decisions.

Learning Objectives
After completing this activity, learners should be able to:
  1. Describe clinically relevant components of acid-balance physiology.
  2. Analyze simple and complex acid base disorders.
  3. Calculate the anion gap to measure the amount of unmeasured anions and cations in serum.
  4. Assess clinical cases by interpreting acid-base balance, calculating the anion gap and delta ratio, and evaluating for respiratory or metabolic compensation.
