Critical Systems Simulator

Interactive, physiology-driven training tools for critical care. Each module runs live in the browser — no install. Synthesized for teaching only, not for clinical decision-making.

Mechanical Circulatory Support
Available IABP Intra-aortic balloon pump. Live arterial & balloon-pressure waveforms, inflation/deflation timing, the four classic timing errors, and mechanical balloon faults. Available Microaxial Flow Pump Trans-valvular microaxial flow pump — placement-signal ventricularization, motor-current pulsatility, suction, P-levels & weaning, and LV unloading. Available Temporary External Cardiac Pacing Epicardial-wire pulse generator — AAI / VVI / DDD & asynchronous modes, rate, output & sensitivity, capture threshold and the classic faults: loss of capture, under- and over-sensing, and failure to output.
Coming soon VA-ECMO Peripheral femoro-femoral veno-arterial ECMO — centrifugal flow & circuit pressures, differential hypoxia / Harlequin (pre- vs post-ductal SpO₂), LV distension, suck-down chatter, and oxygenator failure.
Coming soon VV-ECMO Veno-venous ECMO — oxygenation vs. sweep gas, recirculation, and cannula configuration.
Coming soon VAD Durable continuous-flow LVAD — pump speed & flow, the pump curve, pulsatility index, reduced arterial pulse pressure, and suction events.
Respiratory
Available Ventilator Pressure / flow / volume graphics across VC, PC & PS modes, best-PEEP mechanics & ARDS predicted-body-weight targets, holds for plateau / auto-PEEP, an esophageal-balloon tracing, and the patient–ventilator dyssynchronies. Available Capnography End-tidal CO₂ time capnogram — the labeled phases & ETCO₂, with the classic pathologies: obstructive shark-fin, hypo-/hyperventilation, rebreathing, oesophageal / apnoea, curare cleft, cardiac oscillations, and hypoperfusion.
Hemodynamics & Renal
Available Swan-Ganz PA-catheter interpretation — float the catheter through RA / RV / PA / wedge with live waveform changes, read the full hemodynamic profile (CVP, PA, PAWP, CI, SVR, PVR, SvO₂), and work through the classic shock states. Available CVP Waveforms Central venous pressure read against the ECG — the a / c / v waves & x / y descents, with tricuspid regurgitation, atrial fibrillation, cannon a waves, tamponade, constriction, tricuspid stenosis and RV failure. Available Arterial Line Damping Over- and under-damping of the arterial trace from the catheter–transducer response — the fast-flush square-wave test, and how damping distorts the measured systolic / diastolic away from the true pressure. Available CRRT Continuous renal replacement — circuit pod pressures (access / filter / return / effluent), TMP & ΔP, SCUF / CVVH / CVVHD / CVVHDF modes, filtration fraction & filter life, regional citrate, and the classic alarms: filter clotting, access failure, return obstruction, and blood leak.
