#238 Continuous Venovenous Hemofiltration CVVH Explained | ICU CRRT Deep Dive

Continuous Venovenous Hemofiltration (CVVH) Explained | ICU CRRT Deep Dive

Continuous venovenous hemofiltration (CVVH) is a core modality of continuous renal replacement therapy (CRRT) used in critically ill ICU patients, particularly those with hemodynamic instability who cannot tolerate intermittent dialysis. In this episode, we take a deep dive into the physiology, mechanisms, and clinical applications of CVVH to help you build a clear, bedside understanding of how this therapy works.

We break down the foundational principles behind CVVH, including convection and solvent drag, ultrafiltration, transmembrane pressure, and solute clearance. We also review key CRRT terminology, replacement fluid strategies, and high-yield clinical concepts that explain why CVVH is commonly used in septic shock, cardiogenic shock, severe fluid overload, and life-threatening electrolyte abnormalities.

This episode is designed for medical students, residents, fellows, ICU nurses, respiratory therapists, emergency physicians, and critical care clinicians who want a strong physiology-based understanding of renal replacement therapy in the ICU.

Topics covered include:
• What CVVH is and how it works
• Convection vs diffusion in CRRT
• Ultrafiltration and net fluid removal
• Transmembrane pressure and sieving coefficient
• Replacement fluid strategies
• Basic CVVH prescription principles
• Clinical indications and complications
• High-yield ICU and bedside pearls

If you want to strengthen your understanding of emergency critical care physiology and ICU management, this episode provides a structured and practical approach to one of the most important therapies in modern critical care.
