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
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, cooling to arrest, VF→asystole, hot shot, delayed myocardial rewarming, and myocardial temperature display.
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.
PROFor students who want exam-style scenarios and perfusionists who want deeper crisis and case variety.
Pre-bypass and wean reminders that log to the event timeline — Pro-gated so free users see the standard, not the full workflow tool.
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).

Yes. It’s a Progressive Web App. Use Install in Chrome/Edge or Add to Home Screen on iOS. A guided tour helps new users find every panel.
Perfusion Nexus is focused on cardiopulmonary bypass machines and CPB procedures — case library and workflows are CPB-centric.
Stripe handles the $14/month subscription. Cancel anytime from the customer portal link in your receipt email. Pro is revoked when the subscription ends.
No. Perfusion Nexus is an educational simulation only. It does not replace clinical training, institutional protocols, or certification.
