Respiratory Rate Reference
Count breaths against age-banded normal ranges — the vital sign everyone can measure and nobody does.
Respiratory rate is the earliest-moving vital sign in deterioration — it shifts before pulse and blood pressure, which is why early-warning scores weight it heavily and why nurses count it quietly while pretending to take a pulse (awareness changes breathing). In children with fever, a rate persistently above the band plus chest in-drawing is the WHO pneumonia assessment trigger — that's a same-day clinician visit.

Frequently asked questions
How does the Respiratory Rate Reference work?+
Respiratory rate is the earliest-moving vital sign in deterioration — it shifts before pulse and blood pressure, which is why early-warning scores weight it heavily and why nurses count it quietly while pretending to take a pulse (awareness changes breathing). The calculation uses the formula: normal adult resting rate 12–20/min; children's ranges run higher. Everything runs instantly in your browser as you type — your inputs are never uploaded.
Is the Respiratory Rate Reference accurate, and what is it based on?+
The method is traceable to authoritative sources, including Royal College of Physicians — NEWS2; WHO IMCI — fast-breathing thresholds in children. Results are estimates — individual variation always applies, so treat the output as a well-grounded starting point.
Is the Respiratory Rate Reference free and private?+
Yes. It's completely free with no sign-up, and all computation happens locally in your browser, so none of your health data ever leaves your device.
Can I use this for medical decisions?+
This tool is for general information only and is not medical advice. Always consult a qualified healthcare professional before making health decisions.
What can I use the Respiratory Rate Reference for?+
It's commonly used for respiratory rate, normal breathing rate, breaths per minute. Count breaths against age-banded normal ranges — the vital sign everyone can measure and nobody does.
