NEWS2 Calculator for Paramedics
Automatic National Early Warning Score calculation across all 7 parameters. Scale 1 and Scale 2 support, clinical response prompts, and full offline operation. Built by UK paramedics.
Why Use a Digital NEWS2 Calculator?
NEWS2 is the standard for early warning in UK pre-hospital and hospital care. Calculating it manually across seven parameters under pressure is error-prone — an incorrect score can mask a deteriorating patient or trigger the wrong clinical response. A digital calculator removes the arithmetic, enforces the correct scoring ranges, and surfaces the recommended response instantly.
No Arithmetic Errors
Automatic totalling across all seven parameters removes the risk of mental arithmetic mistakes on scene.
Instant Response Guidance
Clinical response thresholds display immediately for the aggregate score, so you act on the right information fast.
Scale 1 & Scale 2
Correct SpO₂ scoring for hypercapnic patients at the tap of a button — no need to remember different ranges.
All 7 NEWS2 Parameters
SnapMedic scores every parameter with the correct clinical ranges, automatically totalling to the aggregate NEWS2 score.

NEWS2 Calculator Features
Everything a pre-hospital clinician needs for accurate NEWS2 assessment, built into one free app.
Automatic Score Totalling
Enter the seven parameters and NEWS2 instantly calculates the aggregate score. No mental arithmetic, no risk of addition errors during a busy assessment.
Scale 1 & Scale 2
Toggle between Scale 1 (standard) and Scale 2 for hypercapnic patients. The oxygen saturation scoring adjusts automatically for the correct target range.
Clinical Response Prompts
The app displays the recommended clinical response for the aggregate score — from routine monitoring through to emergency response — aligned with RCP guidelines.
Offline Operation
Works without any internet connection. All calculations run locally on your device — reliable in rural areas, basement flats, and any environment with no signal.
Fast Parameter Entry
Tap through the seven parameters quickly. The interface is optimised for gloved hands and high-pressure assessments, with large touch targets and clear scoring ranges.
Integrated with Observations
NEWS2 scoring integrates with SnapMedic's full observation logging. Parameters recorded in the calculator feed directly into the patient encounter timeline.
