WhiteBoard Medicine - Emergency And Critical Care · Mar 28, 2026 · 29m

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…
