Simulator
The EDFlow EHR simulator for the sandbox and showcase: fire the next event for a visit, run scripted scenarios, autopilot a synthetic department, choose the transport (direct, signed webhook, HL7 v2, FHIR) and control the feed.
- Bac à sable et démonstration seulement
The simulator creates synthetic EHR traffic. It exists only in synthetic deployments (development, the showcase and the integration sandbox). It isn't built into production or customer test, and every simulator function refuses to run there.


Panels
| Panel | What it does |
|---|---|
| Patients | Pick a simulated visit and fire the next plausible event: triage, assign a physician or nurse, order a test, advance a test, result all tests, reassess, consult, disposition, bed steps, depart, left without being seen. New arrival creates a fictional patient and prints a card |
| Scenarios | Scripted runs at 1×, 5× or 20× with progress, pause and cancel |
| Autopilot | A continuous synthetic department with an arrival multiplier (0.5× to 3×) and speed. Stops after 2 hours unless renewed; at most 45 simulated visits per site |
| Transport | Direct, or Signed webhook to /ehr/v1/events with the sandbox source key (exercising signatures, idempotency and per-event results), or send as HL7 v2 or FHIR to demonstrate the adapters |
| Feed controls | Heartbeat on or off (delayed after 5 min, down after 15), send a census or a roster, send 50 duplicates to show idempotency |
| Log | The last 200 events with their ingest status |
| Reset | Reset the showcase data, with a typed confirmation. Refused if any site is pilot or live or any real source is active |
Scenarios
Walk-in discharge; chest pain admitted; abdominal CT with contrast; child with fever and a urine sample; left without being seen after a long wait; left after being seen; assigned then released; serial troponin; observation after anaphylaxis; resuscitation with paused updates; a code with a named patient; duplicate registration; discharge reversal; patient merge; paged Code Blue; staff-only Code White; feed outage with backfill; surge; unknown trauma patient.
