POCUS for Primary Care: Ultrasound Tips for Diagnosing and Managing CHF

A structured POCUS protocol for congestive heart failure assessment integrates three essential views: cardiac ultrasound to evaluate ejection fraction (using muscle thickening, chamber volume change, and mitral valve leaflet position), IVC assessment to determine plethoric status indicating fluid overload, and lung ultrasound to detect pulmonary congestion through B-lines (vertical reverberation artifacts indicating alveolar fluid) and pleural effusion. This three-step approach significantly improves diagnostic accuracy compared to clinical judgment alone, with POCUS demonstrating 92% sensitivity for pulmonary congestion versus 77% for chest X-ray, and 80% specificity for heart failure diagnosis versus 38% for clinical assessment alone.
