Core Tip
Core Tip: Cardiorenal syndrome is often managed through conflicting specialty-specific approaches rooted in outdated assumptions about fluid status and creatinine trends. Emerging data emphasize venous congestion, not just reduced cardiac output, as a key driver of renal dysfunction. Traditional tools lack sensitivity and physiologic specificity. Point-of-care ultrasound (POCUS) offers a real-time, integrative method to assess forward flow, congestion, and extravascular fluid using focused cardiac, venous Doppler, and lung ultrasound. This physiology-based approach enables individualized care, clarifies rising creatinine during decongestion, and fosters consensus across specialties. POCUS should be seen not only as a tool but as a shared clinical language.
