The Anion Gap & Why it Still Matters

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.
