BPSIM · physiology teaching simulation

Blood pressure simulation

An interactive model of the pressure in the human aorta. Change heart rate, contractility, resistance, compliance or the aortic valve and see how pressure and flow change. Two versions are available.

BPSIM Monitor

A bedside-monitor style simulation with a physiological model of the heart and the aorta.

Time-varying elastance ventricle, aortic valve with stenosis and regurgitation, blood inertia
Three-element windkessel with pressure-dependent compliance and pulse wave velocity
Aortic, root and left ventricular pressure, flow, ECG, trend and pressure–volume loop
16 conditions, from exercise and pregnancy to shock, valve disease and AV block
Documented equations, parameters and literature

BPSIM Classic

The original BPSIM, now running directly in the browser without Unity or plug-ins. It keeps the model, the look and the behaviour of the 2019 version.

Two-element windkessel after Randall (1981)
Heart rate, systole duration, peripheral resistance, compliance and stroke volume
Pressure and flow curves, systolic and diastolic trend, MAP and cardiac output
