What it is
Fast adult and paediatric dosing, with the calculation done for you and the source in view.
Cardiac-arrest cards, infusions and time-critical protocols, a tap away.
Airway and equipment sizing plus age-based vital-sign reference, all in one place.
Designed for a moving ambulance and a dark room at 3am — it works without signal.
The story
In 2010, I built a pocket guide to make critical moments a little more manageable — something fast, accurate and easy when seconds count.
Over the years, it was shaped by the paramedics who carried it. Every trauma, every cardiac arrest, every experience enhanced it. Growing into something built not in an office, but on the road by clinicians like you.
ResusOne is the culmination of that work — shaped by decades of paramedics asking for the next edition. One simple belief: that every clinician deserves the tools to make safe, confident decisions under pressure.
My hope is that ResusOne gives you the confidence and clarity to make great decisions when they matter most.
