Realistic cardiopulmonary bypass simulation: patient monitor, HLM, cardioplegia, ABG trends, case timers, guided onboarding tour, and safety interlocks — free to start. Pro adds advanced cases, crises, cell saver, custom patients, and more.
No account required for Free · Install as a PWA on desktop or phone · First-run guided tour included
Snapshot of live parameters you’ll drive in the sim — patient monitor, flows, ACT, and myocardial temperature. Open the full console →
Three steps from zero to a full practice run. No account required to start.
Launch the simulator in your browser. Take the guided tour, pick a routine CABG case, and explore the patient monitor and heart-lung machine.
Heparin and ACT, complete the time-out checklist, open the venous line, go on bypass, protect the heart, manage gases and volume, then wean with criteria.

Free deep-dive topics: on-bypass targets, pH-stat vs alpha-stat, TEG patterns, surgeries, and devices — plus core CPB skills. No Pro required.
Flow, MAP, SvO₂, DO₂i, ACT, reservoir, ALP — teaching ranges and red flags.
How temperature changes blood-gas strategy during hypothermia and DHCA.
R, MA, α-angle, LY30 — recognizing heparin effect, weak clot, and lysis.
CABG, valves, dissection, arch/DHCA, redo, MICS — the perfusion view.
Oxygenator, cell saver, IABP, Impella/LVAD concepts, ECMO vs CPB.
Anticoagulation, ACT checks, AT-III, and protamine safety.
Core CPB skills free. Advanced training and educator tools in Pro.
ECG & ART waveforms, HR, MAP, CVP, PAP, SvO₂, ACT, urine, CI, DO₂ / DO₂i / O₂ER / PVR, NIRS, and ABG with live trend graphs.
Dedicated clocks for Pump, Clamp, Ischemia, Circulatory Arrest, and Reperfusion — aligned with real case documentation.
Reservoir, arterial flow, FiO₂ / sweep / H-C, VAVD, pump sucker with heparin/protamine safety rules, filter purge, line pressures.
Antegrade / retrograde with delivery visualizer, cooling to arrest, VF→asystole, hot shot, delayed rewarming, temperature display, and myocardial protection graph.
Weight-based heparin, ACT checks that drift on bypass, AT-III, protamine interlock, pressors, inotropes, bicarb, insulin/D50, Lasix.
Spotlight tour of Patient Monitor, HLM, cardioplegia, and Interventions. Replay anytime with the Tour button.
Start/pause collection, process bowl, return washed RBCs. Sucker recirculates to reservoir when saver is paused — like the OR.
PROExpanded art/ven Fr sizes, art & venous sites. Pro cases auto-fill recommended cannulation with an on-screen guide.
PROBuild fictitious patients: name, age, sex, height, weight, Hct/Hb, diabetes, glucose, and problem history for tailored drills.
PRORedo sternotomy, Type A dissection, AVR/MVR, ASD, MICS, TAVR crash, pediatric VSD, arch/DHCA — CPB-focused library.
PROHypotension plus Pro events: air, cerebral malperfusion, acidosis, bleeding, pump failure, oxygenator failure, and more.
PRORecord vitals every 5s, replay, export/import JSON, delete runs. Temporary pacemaker with AAI/VVI/DDD teaching panel.
PROPre-bypass checklist for every user: heparin/ACT, de-air, cannulas secure. Venous clamp stays locked until time-out is complete.
Live trend of myocardial vs blood temperature — see cooling during cardioplegia and rewarming over ischemic time.
Give bicarb, saline, PRBC, albumin, CaCl, or KCl and watch pH, BE, Hct, Na, K respond — teach cause and effect.
PROAir, low reservoir, pump/oxygenator failure, and more open a step-by-step protocol checklist so events become teaching moments.
PRORandomize height, weight, Hct, comorbidities, and surgery type so students adapt instead of memorizing one CABG profile.
PROFor students who want exam-style scenarios and perfusionists who want deeper crisis and case variety.
Pre-bypass time-out is required for every user before venous clamp opens. Wean checklist and crisis step-by-step protocols unlock in Pro.
As you reduce flow, volume returns, CVP rises, and pulsatile ART returns when the heart ejects — practice coming off bypass.
Install on desktop, tablet, or phone. Works offline for core practice after first load (license validation when online).
Everything you need to learn the path onto and off bypass is free. Pro expands cases, crises, and educator tools.
