Clinician-built simulation

The patient deteriorates. Your students decide what happens next.

EyanSim turns a tutorial room into a critical-care bay. One physiology engine drives the ventilator, the monitor and the instructor console in real time — on four iPads, offline, with no manikin and no capital works.

The platform

Four apps. One patient.

One verified physiology engine drives all four applications. A new product does not need a new implementation of the physics, and a correction to the physics reaches every app at once — which is the only sense of the word "platform" that matters to the person buying it.

Ventilator simulator

Loops that come out of the mechanics, not out of an animation.

Every point on these curves is solved from the equation of motion at each substep — airway pressure against the compliance and resistance of the lung being ventilated. Change the patient's mechanics and the loop changes shape for the reason it would at the bedside. A simulator that reproduces the settings teaches button-pressing; one that reproduces the mechanics teaches reasoning.

The actual apps

Not mockups. Screenshots.

Captured on an iPad Pro from the current build. Everything on these screens is produced by the physiology engine while it runs.

  • Ventilator — Scalars
    Ventilator — Scalars Airway pressure, flow and volume against time, sweeping left to right exactly as the device draws them.
  • Patient Monitor — Anaesthesia
    Patient Monitor — Anaesthesia ECG, plethysmograph, arterial and pulmonary pressures and capnography, driven by the same patient the ventilator is ventilating.

The bundle

Four iPads in enclosures. That's the whole installation.

No manikin, no compressor, no capital works. The units dock and charge over USB-C, the enclosures are fabricated locally so a damaged one is replaced in days rather than shipped from Europe, and the simulation runs on the room's own Wi-Fi with no internet connection at all.

  • Sets up in a tutorial room, not a purpose-built centre
  • Locally fabricated enclosures with integrated USB-C dock and charging
  • Runs fully offline — no student data leaves the building

Standard four-unit configuration. App screens are real captures from the current build; the enclosures are drawn to scale, with photographs of the fabricated units to follow.

Technology

A simulator is only as good as the physiology underneath it.

Most training software animates a plausible-looking waveform. Ours solves the mechanics and the circulation — pressures, flows and gas exchange responding to the lung being ventilated and the drugs being given — then draws whatever that produces.

    Solved, not drawn

    Ventilator waveforms come out of the single-compartment equation of motion, computed at every substep. Shape, delivered volume, trapping and the response to a leak all emerge from that relationship rather than being animated to look convincing.

  • 02

    One engine, four apps

    The monitor, the ventilator, the console and the student app all read the same physiology state. A ventilator intervention shows on the monitor because it is the same patient — not because a link was authored between two applications.

  • 03

    Correct for the patient in front of you

    Five classes from preterm neonate to adult, each with its own compliance, resistance, functional residual capacity and setting ranges. Disease severity is expressed as a fraction of that class’s own normals, and adult-only pathology cannot be selected on a neonate.

  • 04

    Nothing leaves the room

    The simulation runs entirely on the devices present, over local Wi-Fi, with no internet connection. No student data leaves your network because none is collected.

See it running on your own iPads.

A 30-minute walkthrough with the person who built it. We'll run a case end to end, and you can put it in front of your own students the same week.
