The call has started. The patient is waiting. And the clinician is alone with their thoughts ... until now.

Every ambulance call begins the same way. A dispatch notification. A vehicle moving. A clinician alone, working through what might confront them and what they will do when they arrive. That window — from dispatch to arrival — is what Joe Acker calls dead time. It is largely unexamined in the research literature, inconsistently used in practice, and quietly one of the most consequential periods in prehospital care.

Simon Grosjean is an EMS physician in Aosta Valley, northern Italy. He encountered that silence on a night call - a routine case that became a breech presentation, no specialist reachable, searching the internet on his phone when his EMT partner raced him to the scene. The delivery went well. Simon was honest about why: physiology, not preparation: “This time I was lucky.”

He spent the following year building something so he would not have to rely on luck again.

EMSy is the AI-powered clinical decision support tool Simon developed not a diagnostic engine nor to replace clinical judgement. What it does is act as what Simon calls “a good librarian”: drawing together dispatch information, medication histories, ECG findings, and prehospital literature into a structured summary a provider can scan while their hands are already working. Voice-prompted. One app. No switching between tabs.

In this episode, Joe and Simon work through what dead time actually is, why dispatch framing creates tunnel vision before the clinician even arrives, and why paramedics so often leave calls without ever knowing what their patient’s diagnosis turned out to be. They then road-test EMSy against a chest pain scenario - not for the clinical content, but for what it reveals about how much cognitive preparation is possible in that pre-arrival window, and how little of it currently happens by design.

The episode closes on a question that matters for every service, everywhere. EMSy is about to be piloted in Mongolia - a place with different languages, different systems, and the same fundamental problem: a clinician, alone, moving, deciding.

This is not a conversation about technology replacing people. It is about what fills the silence before you arrive.

When Dr Suvd Nugui returned to Mongolia after training in the United States, she came back to a system where most of her colleagues had never heard the word “paramedic.” Neither had her parents.

Her solution was simple and radical: if she could not be everywhere, she could train people who could. Seven years later, she is training more than 80 clinicians and drivers annually with a team of international paramedics. One result: Mongolian EMS doctors are performing ECG interpretation on monitors that sat unused for months because no one knew how to operate them.

In this episode, Dr Suvd speaks with podcast host Hamish McLean about what sustained prehospital capacity-building actually looks like from the inside - the cultural barriers, the equipment gaps, the communication challenges and why a team that keeps coming back changes everything.

About Dr Suvd Nugui Dr Suvd Nugui is a Mongolian cardiologist and in-country director of the EMS Global Foundation’s Mongolia programme, where she has led training delivery and local stakeholder engagement since 2018.

Paramedic James Stubley comes from one of the most advanced prehospital aeromedical platforms in the UK. Double-crewed, doctor-qualified, critical care at altitude. He is now teaching Mongolian on-road ambulance doctors and coming back for a second year to finish the job he started.

This episode is a short, direct answer to this question: can you deliver emergency care with basic equipment, or does complexity save lives? James has now worked in both environments. His answer matters.
