Monitor-first interface
ECG, capnography and key observations remain visible beside the controls used during a teaching session.

The monitor and the controls in one view.
The challenge
Rhythm recognition and resuscitation practice are easier to teach when the monitor and controls stay in the same view. A static rhythm chart cannot show the pace of a session, while a fragmented interface makes it harder to change the scenario without interrupting it.
The system
We built a cross-platform monitor interface around selectable ECG rhythm strips, a generated capnography trace and adjustable vital signs. A shared sweep clock keeps the two traces visually aligned. Scenario presets provide starting rhythm and vital values, while the control dock keeps defibrillation, pacing, CPR, rhythm selection and medication entry close to the display.
Product capability
What it enables.
An educator can start from an ACLS, PALS or NRP preset, switch among 33 rhythm options, tune vital signs and operate the simulator controls without leaving the monitor. The display, controls, sounds and session timer provide a continuous setting for practice and discussion.
Inside the simulator
How it works.
- 01
One screen for the whole exercise
ECG and capnography traces, key observations and the control dock share one view, so the scenario never has to leave the monitor.
- 02
Start with a scenario, then adapt it
ACLS, PALS and NRP presets supply a starting rhythm and vital signs. From there the educator can switch among 33 rhythm options and tune the observations as the exercise continues.
- 03
Practise the sequence
Select an energy level, charge and deliver a simulated shock, toggle sync, set the pacer’s rate and output, run CPR and record a medication’s drug, dose and route, all from the same workspace.
- 04
Built to keep time together
ECG and capnography share one monitor clock and sweep position, so the two traces move in step. The ECG combines supplied rhythm strips with generated traces; capnography is generated.
Under the hood.
SimRhythm is built with Expo, React Native and TypeScript, with Expo Router for navigation and React Native Skia drawing the monitor traces. One codebase runs on iOS and iPad, Android and the web.

Three considerations
Scenario flexibility
ACLS, PALS and NRP presets set an initial rhythm and vital signs; educators can adjust them as the exercise continues.
Hands-on controls
Charge and shock, sync, external pacing, CPR, rhythm selection and medication entry are available in the same simulator workspace.
The sector around it
What’s changing in medical education.
Our line on AI here: AI should not set clinical values, rhythms or algorithm steps, and it should not decide whether a learner passes. Those stay with qualified educators.
