How it works

Three steps. About two minutes.

No sim-lab infrastructure, no AV cart, no per-seat licences on tablets. If your room has Wi-Fi — or even just a phone hotspot — it can run ResusSim.

Install on one computer

A Mac or Windows PC becomes the host. Download, open, done — the first-run wizard checks your network and tells you in plain language that devices can connect.

Devices scan a QR code

Each bedside iPad, student phone or wall TV opens its screen instantly in the browser. Choose what each one shows — monitor, vent, EMR, POCUS, pumps, phone.

Connect the room: a QR code and room code for pairing, five displays paired, and each listed with the device it shows and its layout

Run the case

Drive everything from the instructor console: one physiologic model pushes coherent vitals to every screen at once. Pause, escalate, defibrillate, debrief.

Instructor console during a VF arrest: rhythm set to VFib, vitals sliders in UK units, the arterial line in, and the session clock with play, pause and stop

Features

Every screen a resus room needs.

Each device is driven by the same physiologic engine — change the patient once and the monitor, capnograph, ventilator and EMR all agree, beat for beat.

Patient monitor, defib & pacer

A patient monitor simulator with waveform-accurate ECG, pleth and capnography, and rhythms from sinus to VF. Defibrillate, cardiovert, pace — energy, mode and pad state all matter, and CPR shows on the tracing.

Patient monitor in VF arrest in defib mode: VF/VT alarm, CPR banner counting down to the rhythm check, compression-generated arterial pressure 60/16, RR 22 on the ventilator, EtCO₂ 1.9 kPa, 200 J charged and SHOCK ready

EMR with real lab behaviour

Order meds by name, release labs and imaging on your cue. Results arrive with reference-range scales that flag highs and lows — like the chart your learners will actually use.

EMR results: a blood gas in UK units with pH 7.26, pCO₂ 4.4 kPa, HCO₃ 15, base excess −9, lactate 5.7 and glucose 9.6 flagged against their reference ranges

POCUS

Bedside ultrasound views — cardiac, lung, abdominal — matched to the scenario, with depth, gain and freeze controls that behave like the real probe.

Ventilator & pumps

A ventilator screen with modes, pressures and alarms, plus infusion pumps whose drips actually move the physiology — start noradrenaline and watch the pressure respond.

Consult phone

Learners phone a specialist; the instructor answers as cardiology, ICU or tox — by text, prerecorded voice, or live two-way call audio.

Recording & debrief

A room camera records the sim with every action time-stamped on the timeline. In debrief, search for “adrenaline” and the video jumps to the moment it was given.

Wall display

Point any TV browser at the wall view: one pane on a phone, two on a laptop, a full grid on a 4K wall screen — it adapts to whatever glass you have.

AI inside

Describe a patient. Get a case.

ResusSim uses AI where it genuinely changes teaching — and tells you honestly what’s live today versus on the roadmap.

✓

Dynamic patients from one sentenceLIVE

“58-year-old cardiogenic shock post-MI, progressive hypotension…” — the engine returns a physiologically coherent patient with a timed, untreated course that evolves until your learners intervene.

✓

Speech catches the medsLIVE

Say “giving adrenaline 1 milligram” out loud and it lands on the timeline, time-stamped — no scribe needed.

✓

Searchable debriefLIVE

Filter the event log by action or category and jump the recording straight to that moment.

Camera-detected actionsROADMAP

The room camera recognising chest compressions and bag ventilation — and driving the physiology from them. In design now; everything runs locally, never in the cloud.

Use cases

Built for wherever you teach.

From a purpose-built sim centre to a corridor drill on hospital Wi-Fi — the session never depends on the internet, so it works where your learners are.

A resuscitation team in a simulation centre works on a manikin: compressions, bag-mask ventilation and drugs drawn up, with the monitor on a wall screen and an instructor watching from the control room

Simulation centres

Replace ageing proprietary monitors and per-room licences. Every bay runs from one host with the screens you already own.

An in-situ arrest drill in a hospital ward bay: a nurse does compressions on a manikin while a doctor places defibrillator pads, the monitor on a tablet clamped to the drip stand and a laptop on the trolley

In-situ hospital training

Roll a laptop onto the ward and run the arrest where arrests actually happen. Hostile hospital Wi-Fi? A phone hotspot is enough.

Medical and nursing students with their phones gather around a manikin while a tutor points out the waveforms on a bedside tablet monitor

Medical & nursing education

Zero installs on student devices means zero IT tickets. Learners scan, join, and every screen is theirs to read and act on.

Two paramedics in the back of an ambulance ventilate a manikin on the stretcher, the monitor on a tablet mounted on the cabinet wall and a laptop on the bench seat

EMS & prehospital

A MacBook and an iPad hotspot make a complete mobile sim kit — in the rig, in the station, in the field.

Questions

What people ask first.

What is ResusSim?

A resuscitation simulator that turns the screens you already own into a working resus room. One Mac or Windows computer runs the case; iPads, Android tablets, phones, laptops and wall TVs join from their browser and become the patient monitor, defibrillator, ventilator, infusion pumps, EMR, ultrasound or consult phone.

Can a tablet be the patient monitor?

Yes — it’s the most common setup. Scan the room’s QR code and the tablet becomes a bedside monitor with ECG, pleth, arterial line, capnography, NIBP and temperature, plus defibrillation, synchronised cardioversion and pacing. Nothing is installed on the tablet.

Does it need the internet?

A running session doesn’t. The simulation runs over your own Wi-Fi or a phone hotspot, and sessions and recordings never leave the host computer. Only the optional AI features — building a case, writing its goals, describing an ECG — need a connection.

What does it cost?

Nothing during the beta: every feature is free through 31 December 2026, on Mac (Apple Silicon and Intel) and Windows. Joining devices need only a browser.

Who is it for?

Simulation centres, in-situ drills on the ward, medical and nursing schools, and EMS teams — anyone teaching ALS or ACLS-style arrests, the deteriorating patient or critical care who wants realistic monitors without proprietary hardware.

How is it different from a monitor app?

A monitor app fakes one screen. In ResusSim one physiological engine drives every device, so a change to the patient shows on the monitor, capnograph, ventilator and EMR together — and the learners’ CPR, shocks, drugs and ventilator settings change the patient.

Free while in beta.

Full-featured through 31 December 2026 · Mac (Apple Silicon & Intel) and Windows · joining devices need only a browser.

The AI features (building a case, writing its goals, describing an ECG) run on a commercial AI service that charges for every request, and we’re paying for it during the beta. We hope to find a sponsor to cover these costs, so ResusSim can stay free for as long as possible and the features already in the pipeline can follow. Interested in sponsoring ResusSim?
