Bedside SWAN

Bedside SWAN turns six things you can get with a phased array probe and a blood pressure — heart rate, MAP, LVOT VTI, IVC, lungs and the patient's size — into cardiac output, cardiac index, stroke volume, systemic vascular resistance and a named shock profile. Built for medical students, residents and clinicians newer to point-of-care ultrasound. Free: Flow, vasoactive support, right atrial pressure, lungs, profile classification, conditional caveats, "how to measure" hints under every input, and a copyable report. Pro (one-time purchase, no subscription): diastology and LV filling pressure, right ventricle, pulmonary circulation (mPAP, PVR, TPG, DPG, compliance, ePAPI, Qp:Qs), VExUS grading, and pericardial effusion and tamponade — each with a measurement guide. Nothing you enter leaves your phone. No accounts, no analytics, no patient identifiers. Educational tool — not a medical device.
