Free POCUS Teaching Case: Bayesian Reasoning at the Bedside

A 67-year-old man with decompensated heart failure. Creatinine rising. Urine output falling. The intern asks the question that splits the differential: does he need more fluid, or does he need diuresis?

This free case study walks through the full Bayesian chain: pre-test probability, scan findings (IVC, hepatic vein Doppler, portal vein pulsatility, intrarenal venous Doppler), likelihood ratios, and the posterior decision that changed management. It's the reasoning layer most POCUS courses skip — not just what you're looking at, but how to think about what you're looking at.

What you'll get:

• A single clinical case with the full reasoning chain exposed
• VExUS protocol findings explained in context — not as abstract patterns
• The Bayesian calculation — pre-test odds × likelihood ratio → posterior — applied to a real bedside decision

No slide deck. No certificate. Just the thinking behind the scan.
