Glasgow Coma Scale (GCS) Calculator

Calculate the Glasgow Coma Scale (GCS) from the three response components: Eye Opening (E, 1–4), Verbal Response (V, 1–5), and Motor Response (M, 1–6). Total = E + V + M, range 3–15. Supports the '1t' notation for intubated/untestable verbal response (counted as V = 1, with an annotation, and recommends reporting the E_M_V component string). Severity bands: 13–15 mild, 9–12 moderate, 3–8 severe (severe scores commonly prompt airway protection). Derived from Teasdale & Jennett, Lancet 1974, with the Lancet Neurology 2014 review and 2024 update. Not medical advice.
