THE ROLE ARCADE • ACTIVE EXPERIENTIAL SIMULATION

Test-Drive Real Clinical Care-Team Tools

Forget generic quiz questions. The Role Arcade lets students and educators step directly into the hot seat of essential healthcare professions. Experience the actual day-to-day decisions, calculations, and mechanical pressures of hospital medicine.

1. Authentic Clinical Cockpits

Not multiple-choice trivia. Manipulate realistic bypass pump flow, calculate renal clearance, and time MRI contrast injections.

2. Mission Briefings Included

Every console features an expandable step-by-step playbook explaining what is happening, what to click, and target numbers.

3. Zero Prior Jargon Needed

Every medical acronym (MAP, SvO₂, CrCl, TOF) has plain-English tooltips so any 9th–12th grader or teacher can succeed.

CLINICAL COCKPIT WORKSTATION: AUTHENTIC OPERATING DISPLAY
OR-04 • CPB TELEMETRY ACTIVE

Case: Aortic Valve Replacement (Cardiopulmonary Bypass)

1. The Clinical Scenario (What is happening)

In OR-04, the cardiac surgeon is performing an open-heart aortic valve replacement. To operate safely on the valve, the patient's heart must be completely stopped. You are standing two feet away operating the cardiopulmonary bypass console, which functions as the patient's mechanical heart and lungs.

2. Your Mission Objective (How to succeed)

Maintain physiological blood pressure (MAP 65–85 mmHg) and organ oxygenation (SvO₂ > 70%), prevent catastrophic blood clotting in the machine's plastic circuit (keep ACT > 400 sec), rewarm the patient to 37°C, and successfully wean circulation back to the native heart.

No medical experience required
1Target: > 400s
Check Anticoagulation (ACT)

Blood rapidly clots when contacting synthetic plastic tubing. Watch the Activated Clotting Time (ACT). If it dips towards 400s, click 'Administer Heparin Bolus' immediately.

An ACT below 400s causes fatal oxygenator thrombosis within minutes.
2Target: 4.0 - 4.8 L/min
Balance Pump Flow & MAP

Adjust Slider 1 (Arterial Roller Pump Speed) so that Mean Arterial Pressure (MAP) stays in the safe 65–85 mmHg green zone.

Never push flow above 5.4 L/min! Excessive shear stress crushes red blood cells (hemolysis) and damages the kidneys.
3Target: SvO₂ > 70%
Set Oxygen Delivery (FiO₂)

Adjust Slider 2 (Gas Blender FiO₂) around 60%. Monitor Venous Saturation (SvO₂) to verify that vital organs (brain, liver, kidneys) receive enough oxygen.

SvO₂ measures oxygen leftover after tissues feed. A low SvO₂ means organs are suffocating.
4Target: 37°C Core
Rewarm & Wean Bypass

When the surgeon completes the valve suture, click 'Rewarm Patient to 37°C'. Once the heart warms and telemetry is stable, click 'Wean From Bypass' to release the cross-clamp.

The heart will resume spontaneous rhythm as normal blood flow returns.
Plain-English Concept: Cardiopulmonary Bypass (CPB)

When a surgeon operates inside the heart, the heart cannot be beating or filled with blood. A heart-lung machine diverts dark blood from the patient's veins, filters and oxygenates it, warms or cools it, and pumps bright red blood directly back into the aorta.

Why This Matters in Modern Healthcare

Cardiovascular perfusionists earn six-figure salaries ($140K–$195K+) with only 6 years of post-high school education (4-year Bachelor's + 2-year Master's). They work on the frontline of open-heart surgery without attending 4 years of medical school or 5+ years of surgical residency.

The Cardiovascular Perfusionist Behind the Dials$153,300 Median US Salary

While the cardiac surgeon repairs the aortic valve, the Perfusionist operates this exact console standing two feet away. A 2-year accredited master’s degree puts you in this seat earning six figures right out of school - combining high-stakes fluid dynamics, hematology, and pharmacology without 8 years of residency.

Console Chronology:
08:15 - Aortic & venous cannulation verified.
08:20 - Initial Heparin 300 U/kg administered. ACT: 480 sec.
08:25 - Cardiopulmonary bypass initiated. Heart arrested with cold cardioplegia.
