Glasgow Coma Scale Calculator
E-V-M scoring with the component notation clinicians actually hand over — and the intubation line.
Teasdale and Jennett designed it for *trend* monitoring — a drop of 2 points matters more than any single value, and the motor component carries most prognostic weight. Components beat totals in handover ('E3V4M5', not '12') because different combinations mean different things. 'GCS ≤8, intubate' is the airway adage; intubated patients chart V as 'T'.
