Our Mission: Accuracy Through Evidence
In clinical education, precision matters. mapcalculator.org was created to provide a transparent, reference-backed alternative to 'black box' calculators. We do not provide medical advice; we provide efficient access to established medical formulas and guidelines.
Editorial Methodology & Verification
Our content is not generated by AI or anonymous writers. It is meticulously curated from primary medical literature using a three-step verification process:
1. Primary Source Selection
Guideline-First Approach
We prioritize data from Tier-1 international guidelines (Surviving Sepsis Campaign, AHA/ASA, Brain Trauma Foundation) and standard physiology textbooks (Guyton & Hall).
2. Formula Verification
Transparent Math
Every calculator on this site displays its underlying formula and logic. We do not use 'proprietary algorithms.' You can always see exactly how the result is derived.
Strict Editorial Standards
- Transparency: We clearly distinguish between standard mathematical formulas (e.g., MAP) and clinical interpretation ranges.
- Citations: Every key medical claim is footnoted with a direct link to the DOI or PubMed entry of the source material.
- Updates: We monitor major guideline releases (e.g., SSC updates) and revise our targets and logic accordingly.
Disclaimer on Professional Use
This website is an educational aid and clinical reference tool. It does not replace professional training or institutional protocols. Calculations should always be cross-verified when used in critical care settings.
