ER Simulator is an educational simulation tool for licensed clinicians only. It does not provide medical, legal, or practice advice. Always follow your formal training, supervising teams, local laws, and hospital protocols before making real patient decisions.
Built by an Emergency Medicine clinician & certified sim facilitatorFor licensed clinicians · Educational simulation only

Emergency medicine simulations with AI voice-responsive patients that feel like your own mobile sim lab.

ER Simulator is an AI voice-to-voice rehearsal partner: you speak, the simulated patient or facilitator answers back, and the monitor reacts in real time. It’s built for physicians, PAs, NPs, and residents with formal training—especially anyone prepping for EM oral boards, mock codes, or complex consults who just wants more reps between shifts, similar to Rosh Review, OnlineMedEd, or FOAMed cases.

ER Simulator is for informal educational experiences only and is not a substitute for formal medical training or professional advice. By participating you agree to stay within your licensed scope, follow local hospital protocols, and comply with all applicable laws and governing bodies before making patient-care decisions.

No credit card required during early access. Not for real patient use. Always defer to your supervising team, accrediting bodies (AMA, ACEP, NCCPA, ANCC, etc.), and local laws before acting on anything you practice here.

“Patient is a 54-year-old with chest pain and hypotension… What do you want to do first?”

Built to sharpen your emergency department thinking.

ER Simulator is being designed to mirror how you actually think, talk, and move in the ED—minus the 3 a.m. pager.

Voice-to-voice, mock interactive encounters

Use natural language to take a brief history, get exam insights, give orders, and formulate your plan. Our AI voice-to-voice simulation keeps the patient talking back instantly—just like a bedside drill.

Dynamic vitals & monitor

Watch the rhythm, pressure, SpO₂, and more respond in real-time to your interventions—or to delays.

Case library you’ll actually remember

High-yield EM cases built around pattern recognition, cognitive traps, and debriefs so the learning sticks.

Realtime voice simulation built for clinicians

Talk to the AI patient like you would in the trauma bay and hear the answer within a heartbeat. The facilitator voice keeps you honest, nudging vitals, asking “anything else?” and mirroring the on-shift pressure—without scripted menus or tech tinkering.

  • Dual voice sessions (patient + facilitator) mimic the patient encounter and charge nurse coaching at the same time.
  • Every reply references the scenario roadmap yet stays clearly fictional, honoring our “not medical advice” promise.
  • Runs on your laptop, tablet, or phone—no sim lab crew, mannequins, or setup windows.

What the AI voice-to-voice flow feels like

  1. 1. You speak orders, questions, or reassessments into your mic.
  2. 2. The simulator listens instantly and keeps pace with your train of thought.
  3. 3. Patient, nurse, and facilitator voices answer with natural tone and urgency.
  4. 4. The monitor shifts accordingly, and each turn is saved for coaching or oral board review.

Note: All content remains fictional and educational. Users must follow their licensing, local laws, and hospital protocols before translating any insights.

How ER Simulator will work

1

Pick a case & acuity

Choose from chest pain, dyspnea, trauma, OB, peds, and more. Dial the chaos up or down.

2

Talk & practice in real time

Speak to the simulated patient and nurse, get exam insights, give orders, and shape your plan—fictional practice only, never for real patients.

3

Debrief & grow

See what went well, what was missed, and then reinforce the topic through official oral board prep, CME, or your hospital simulation program.

Designed for Emergency Medicine oral board prep

Oral boards require rapid synthesis, clear communication, and the ability to verbalize next steps under pressure. ER Simulator lets you rehearse those skills in realistic voice-driven cases, then cross-check with your program’s rubric or attending feedback.

  • Practice explaining differential diagnoses, orders, and reassessments aloud—the same cadence you’ll use during oral boards.
  • Use fictional patients to sharpen pattern recognition (sepsis, ACS, pediatric resus) without ever touching real patient care decisions.
  • Share session logs with mentors or coaches to get coaching on structure, not answers.

Oral board rehearsal checklist

  • ☑️ State the chief complaint and sick/not-sick status clearly.
  • ☑️ Call out immediate interventions (ABCs, monitors, access) verbally.
  • ☑️ Explain differential and critical actions while the AI patient responds.
  • ☑️ Summarize plan and next reassessment before ending the encounter.

Reminder: This is supplemental practice only. Always rely on your oral board curriculum, program directors, and accrediting bodies for official preparation.

How to use ER Simulator responsibly

Think of ER Simulator as a study buddy: it encourages you to review clinical frameworks but never replaces formal education, credentialing, or CME. You remain solely responsible for your practice decisions.

Not medical advice. This platform does not diagnose, treat, or prescribe. For authoritative instruction, follow your medical school, residency, or recognized associations (AMA, ACOEP, NCCPA, AANP, etc.).

Stay within scope. Only licensed clinicians may use ER Simulator. You must adhere to your licensure requirements, supervising physicians, and institutional protocols at all times.

Follow local law & policy. We provide no legal counsel. Consult your hospital, EMS agency, or legal advisors for documentation, billing, or regulatory questions.

Fictional scenarios only. Never use ER Simulator to manage real patients. Translate lessons into practice only through approved pathways such as residency conferences, CME, or hospital simulations.
