How to Calculate Medical Calculators
What is Medical Calculators?
Medical calculators assist clinicians and paramedics in rapidly assessing patient severity, risk stratification, and clinical scoring — from neurological status to stroke and cardiac risk.
Step-by-Step Guide
- 1Glasgow Coma Scale: eye (1–4) + verbal (1–5) + motor (1–6) = 3–15 total
- 2APGAR score: appearance, pulse, grimace, activity, respiration — 0–2 each
- 3CHADS-VASc: risk factors scored to estimate stroke probability in AF
Worked Examples
Input
GCS: eyes open to voice (3) · confused speech (4) · withdraws to pain (4)
Result
GCS = 11 (moderate brain injury)
GCS ≤ 8 typically requires intubation; < 3 is minimum possible
Common Mistakes to Avoid
- ✕Using medical scores without clinical context — scores supplement, not replace, clinical judgment
- ✕Forgetting to reassess dynamic scores over time
