11 interactive modules
- Full laboratoryRun the full heart simulation with linked PV loops, pressures and metrics.
- Pressure-volume loopsChange preload, afterload and contractility and watch the PV loop move.
- The cardiac cycle (Wiggers)See pressures, volumes and valve events line up over one heartbeat.
- Starling and venous returnSee how cardiac output and venous return meet, and what shifts them.
- Waveform recognitionLearn to tell catheter pressure waveforms apart in each chamber.
- Valve and disease explorerLoad valve lesions and cardiomyopathies and see their hemodynamics.
- Shock and drug effectsTry shock types and drugs and see how pressures and flow respond.
- Mechanical support and shuntsAdd support devices or shunts and watch the circulation change.
- Heart-lung interactionSee how breathing and ventilation change heart pressures and output.
- Measurement and catheterizationPractise cath measurements and spot when the readings mislead.
- Practice casesGuided cases: predict, try it, observe, explain, then apply.
