Continuous Venovenous Hemodialysis (CVVHD) is a core modality of continuous renal replacement therapy (CRRT) — but many clinicians struggle to fully understand how diffusion-based clearance works in the ICU. In this episode, we break down CVVHD step-by-step, including dialysate flow, solute diffusion, ultrafiltration control, effluent rates, clearance principles, and how CVVHD differs from CVVH and CVVHDF. We focus on practical bedside physiology so you can clearly understand how toxins are removed, how fluid balance is controlled, and how settings impact patient care. This episode is designed for emergency physicians, intensivists, trainees, nurses, respiratory therapists, and advanced practice clinicians who want a structured, physiology-first framework for CRRT. If CRRT has ever felt overwhelming, this deep dive will simplify CVVHD into clear, actionable concepts. 🎥 Watch the full YouTube video here: 👉https://www.youtube.com/watch?v=ymfP1RxqOuw 📚 Download the PDF study guide for this video: 👉 https://www.patreon.com/c/WhiteBoardMedicine Patreon members get access to mini-courses, study guides, practice questions, ad-free videos, and in-depth educational discussions designed for emergency and critical care clinicians.
