Cardiac Output Explained: From Physiology to Cardiogenic Shock Diagnosis & Management

Cardiac output is one of the most important—and most misunderstood—concepts in critical care. In this video, we break down cardiac output from first principles and connect it directly to cardiogenic shock, so you can understand not just the numbers—but how to use them at the bedside. We’ll cover: The cardiac output equation (CO = HR × SV) and what it actually means How preload, contractility, and afterload determine stroke volume The Frank-Starling relationship and fluid responsiveness The Fick equation and how cardiac output can be measured How cardiac output fails in cardiogenic shock Practical approaches to diagnosis and management in the ICU and ED This is a high-yield, clinically focused guide for medical students, residents, nurses, respiratory therapists, and physicians in emergency medicine and critical care. 🔗 Download the full study guide + access our complete emergency critical care curriculum:   / whiteboardmedicine   Our Patreon includes: • 📄 Study guides for every video • 🎓 Mini-courses (ventilation, shock, RRT & more) • ❓ Practice questions • 🚫 Ad-free videos • 🧠 A structured ICU curriculum 🎧 Listen to the podcast: https://podcasts.apple.com/us/podcast...
