No inspiratory holds, no circulatory arrest, no extra equipment. FREE • Bedside calculator (Parkin and Leaning, J Clin Monit Comput 2008): Pmsa, Pvr and Eh. • Results update as you type, with checks on impossible values. • "How to measure" guide with diagrams of the Guyton curves and of the effect of fluids and inotropes. IGUYTON PREMIUM • Guyton diagram: venous return line reaching zero flow at Pmsa, the operating point (CVP, cardiac output) and a schematic cardiac function curve; resistance to venous return (RVR), body surface area and the c coefficient. • 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 Pmsa, Pvr and Eh 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.
