EMT-B field simulator

The simulator trains the moment between knowing and doing.

MedRelay is built for the part of EMT training that a question bank cannot reproduce: the noise, the sequence, the timing, and the patient who keeps changing while the student decides what comes next.

Preview mirrors the live simulator: patient monitor, CAD log, and ActionZone decisions.

What it is for

More reps before lab, clinicals, rotations, and ride time.

The simulator helps students practice patient assessment flow, treatment priority, transport decisions, radio-style communication, and PCR documentation before they are under real supervision.

Vitals move while the student decides

Heart rate, blood pressure, respiratory rate, SpO2, mental status, and trend signals change as the scenario unfolds. Waiting too long has consequences.

Actions are scored by order and timing

The simulator does not just ask whether the student picked the right treatment. It checks when they assessed, treated, reassessed, transported, and documented.

EMT-B scope stays enforced

MedRelay trains EMT-Basic decision making. It keeps ALS-only actions out of the correct pathway and frames state-variable items clearly.

Call flow

The run feels like a call, not a worksheet.

01 / Dispatch

Start with a real call shape

Students begin with a complaint, scene context, and patient presentation. The first decision is not an answer choice. It is what to do next.

02 / Assessment

Find life threats under pressure

Scene size-up, primary assessment, vital signs, SAMPLE/OPQRST, lung sounds, pulse oximetry, glucose checks, and reassessment all matter.

03 / Treatment

Treat within EMT-B scope

Oxygen, BVM, airway adjuncts, AED, CPR, hemorrhage control, epinephrine auto-injector, naloxone, glucose, aspirin, and patient-assisted medications are handled at the right provider level.

04 / Debrief

Turn the run into a drill plan

After the call, students see missed priorities, delayed actions, five-domain scoring, and the exact weaknesses to practice next.

Why it is advanced

It grades clinical behavior, not just recall.

A static question can tell whether a student knows the protocol. MedRelay shows whether they can apply it in the correct order while the patient is getting better or worse.

Try the simulator before the next skills lab.

Two scenarios are free. No payment required. Start with a patient presentation, make EMT-B decisions, and watch the monitor, feed, and debrief respond to what you do.
