iElastance vs EchoGuide by ASE

iElastance estimates left ventricular end-systolic elastance (Ees), effective arterial elastance (Ea) and their ratio, ventricular–arterial coupling (VAC), from six values you already have at the bedside: cuff pressures, a standard echocardiogram and two systolic time intervals. No catheter, no extra equipment. FREE • Single-beat calculator (Chen et al., J Am Coll Cardiol 2001): systolic and diastolic pressure, ejection fraction, stroke volume, pre-ejection and total ejection time. • Results update as you type, with checks on impossible values. • "How to measure" guide with diagrams of the method of disks and of systolic times on the LVOT pulsed Doppler. IELASTANCE PREMIUM • Pressure–volume diagram: ESPVR and Ea lines, stroke volume, ESP, EDV, ESV and V0. • Cases: keep your 10 most recent cases, each with as many measurements as you need (baseline, after fluids, after a vasopressor or inotrope…). • Trends of VAC, Ea and Ees over time. • PDF report with results, diagrams, measurement table, trends, method and reference, ready to print or share. • Archive export and import to move your cases to another device. PRIVATE BY DESIGN No account, no analytics, no advertising. Cases and reports stay on your device.
