CPB Simulation Lab · Students & practicing perfusionists

Train like you’re on the
heart-lung machine

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.

📡

Patient monitor

ECG & ART waveforms, HR, MAP, CVP, PAP, SvO₂, ACT, urine, CI, DO₂ / DO₂i / O₂ER / PVR, NIRS, and ABG with live trend graphs.

⏱️

Case timers

Dedicated clocks for Pump, Clamp, Ischemia, Circulatory Arrest, and Reperfusion — aligned with real case documentation.

⚙️

Heart-lung machine

Reservoir, arterial flow, FiO₂ / sweep / H-C, VAVD, pump sucker with heparin/protamine safety rules, filter purge, line pressures.

❄️

Cardioplegia & myocardium

Antegrade / retrograde, cooling to arrest, VF→asystole, hot shot, delayed myocardial rewarming, and myocardial temperature display.

💉

Heparin, ACT & drugs

Weight-based heparin, ACT checks that drift on bypass, AT-III, protamine interlock, pressors, inotropes, bicarb, insulin/D50, Lasix.

🗺️

First-run guided tour

Spotlight tour of Patient Monitor, HLM, cardioplegia, and Interventions. Replay anytime with the Tour button.

🩸

Cell saver workflow

Start/pause collection, process bowl, return washed RBCs. Sucker recirculates to reservoir when saver is paused — like the OR.

PRO
🔌

Cannulation & circuit

Expanded art/ven Fr sizes, art & venous sites. Pro cases auto-fill recommended cannulation with an on-screen guide.

PRO
👤

Custom patients

Build fictitious patients: name, age, sex, height, weight, Hct/Hb, diabetes, glucose, and problem history for tailored drills.

PRO
📚

Advanced CPB cases

Redo sternotomy, Type A dissection, AVR/MVR, ASD, MICS, TAVR crash, pediatric VSD, arch/DHCA — CPB-focused library.

PRO

Crisis training

Hypotension plus Pro events: air, cerebral malperfusion, acidosis, bleeding, pump failure, oxygenator failure, and more.

PRO
📹

Pump-run recorder

Record vitals every 5s, replay, export/import JSON, delete runs. Temporary pacemaker with AAI/VVI/DDD teaching panel.

PRO

Why Pro?

For students who want exam-style scenarios and perfusionists who want deeper crisis and case variety.

CPB checklist

Pre-bypass and wean reminders that log to the event timeline — Pro-gated so free users see the standard, not the full workflow tool.

🫀

Weaning physiology

As you reduce flow, volume returns, CVP rises, and pulsatile ART returns when the heart ejects — practice coming off bypass.

📱

PWA install

Install on desktop, tablet, or phone. Works offline for core practice after first load (license validation when online).

Simple pricing

FAQ

Quick answers before you start.

Do I need an account?

No for Free. Pro is unlocked with a license key after Stripe checkout — no membership login required.

Can I install it on my phone or laptop?

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.

Is this only for CPB, or also ECMO?

Perfusion Nexus is focused on cardiopulmonary bypass machines and CPB procedures — case library and workflows are CPB-centric.

How does billing work?

Stripe handles the $14/month subscription. Cancel anytime from the customer portal link in your receipt email. Pro is revoked when the subscription ends.

Is this medical advice or certification?

No. Perfusion Nexus is an educational simulation only. It does not replace clinical training, institutional protocols, or certification.
