Free Defibrillator Simulator
A free browser-based training tool that lets your students practice rhythm interpretation, defibrillation, pacing, and synchronized cardioversion without needing a physical monitor.
Developed by clinical educators at the University of Colorado, this is the cleanest and most reliable defibrillator simulator available for students today, specifically mimicking the Lifepak® 20e interface.

Why Use a Digital Defibrillator Simulator Online?
For many programs, a $20,000 monitor is hard to come by for every student. Using a virtual defibrillator simulator offers:
- Safe Environment: Practice high-stakes cardiac arrests (VT/VF) without risk.
- Immediate Feedback: Guided tutorials correct your pacing and shocks in real-time.
- Accessibility: As a 100% defibrillator simulator online, you can train from a laptop, tablet, or smartphone anywhere.
What Will You Get?
- Interactive Walkthrough of the Lifepak® 20e’s interface and functions
- Guided Tutorial Mode to practice responding to rhythms like VT, VF, bradycardia, etc.
- Assessment Cases to test your response time in managing cardiac events

Who Should Use This Simulator?
- EMS students learning cardiac rhythm recognition and treatment
- Instructors use this defibrillator simulator as a supplemental resource for classroom lectures or virtual labs.
-
Program directors looking to supplement hands-on skills training with digital tools
Why Is It Free?
This tool was created by clinical educators who believe EMS students should have access to high-quality training regardless of budget or equipment. While we don’t own the software, we recognize it as one of the best defibrillator simulator resources available online and want to ensure it’s easy for the EMS community to find and utilize.
