#256 Non Invasive Fluid Assessment Explained | IVC, VExUS & Passive Leg Raise ICU Guide

In this episode, we break down non-invasive fluid assessment at the bedside, focusing on IVC ultrasound, VExUS (Venous Excess Ultrasound Score), and the passive leg raise (PLR). We walk through how to evaluate fluid responsiveness vs fluid tolerance, when each tool works (and when it fails), and how to integrate these approaches into a practical, physiology-based framework for critically ill patients. This episode tackles one of the most common and challenging decisions in critical care: when to give fluids—and when to stop. By combining ultrasound-based assessment with dynamic testing like the passive leg raise, we outline a more complete approach to hemodynamic assessment in the ICU and emergency department. If you’re a clinician managing acutely ill patients, this episode will help you move beyond guesswork and toward more precise, bedside-driven fluid decision-making. 🎥 Watch the full video here: https://www.youtube.com/watch?v=Raaog7Z6yEI 🚀 Support WhiteBoard Medicine + Get Full Access Get the full study guide for this episode + complete emergency critical care curriculum: https://www.patreon.com/c/WhiteBoardMedicine Our Patreon includes: • 📄 Study guides for every episode • 🎓 Mini-courses (ventilation, shock, RRT & more) • ❓ Practice questions • 🚫 Ad-free content • 🧠 A structured ICU curriculum ⚠️ Disclaimer This content is for educational purposes only and is not intended to provide medical advice.
