Summary
The Broselow tape is a registered color-coded pediatric emergency device. This educational helper reproduces published 2017-edition length and weight zones only. It does not reproduce drug doses or equipment sizes; current physical tapes and institutional references govern clinical use.
How it works
- Enter the child's measured length (head to heel) in centimeters or inches.
- The tool maps the measurement to the corresponding Broselow color zone.
- The estimated weight range for that zone is displayed.
- The page reminds you to verify equipment and dosing on the current physical tape or institutional system.
- Review the disclaimer — never use this helper for real-patient decisions.
Use cases
- Emergency medicine training and simulation scenarios.
- EMS and paramedic education on pediatric weight estimation.
- Nursing students learning pediatric medication dosing principles.
- Quick reference when reviewing pediatric emergency protocols.
- Medical educators building case-based teaching materials.
- Parents and caregivers wanting to understand emergency triage context.
