#214 ECMO Explained: VA-ECMO, VV-ECMO, and When to Use Each

Extracorporeal membrane oxygenation (ECMO) is one of the most complex and powerful tools in critical care—but also one of the most misunderstood. In this episode, we break down ECMO step by step, focusing on VA-ECMO, VV-ECMO, how they work, and when to use each configuration.

We start with the fundamentals of ECMO physiology and circuit components, then walk through veno-arterial (VA) ECMO for cardiac failure and veno-venous (VV) ECMO for severe respiratory failure. Along the way, we highlight key indications, hemodynamic effects, common pitfalls, and complications clinicians need to recognize at the bedside.

This episode is designed as a practical, physiology-based guide for emergency medicine and critical care clinicians who want a clear mental model for ECMO decision-making—whether you’re encountering it for the first time or looking to solidify your understanding.
