The Glasgow Coma Scale is a structured neurological assessment tool that provides a reliable, objective measure of the conscious state of a patient, both at initial presentation and during serial monitoring. Calculate GCS score below:
Every summary carries citations with verbatim excerpts from the source, so you can open it, read it in context and confirm it says what the answer claims. What surfaces are decided by clinical quality, the governed alternative to pasting a clinical question into a general AI chatbot and hoping the answer holds.
Heidi Evidence draws on sources clinicians already trust, from Elsevier and DynaMed to MIMS Australia, and your organization can layer in its own regional pathways, policies, and formularies.
Heidi is the first in its field to hold ISO 42001 certification for AI management. Since Evidence is designed as a reference tool, the clinical call (and the responsibility for it) stays with you.
Evidence draws on the patient visit and its context, so the specifics travel with the question instead of being left behind. When a calculation is involved, the logic sits alongside the result, so you can see how it was reached and confirm it yourself rather than trust a black box.
Making that connection between the patient and the GP, like a puzzle fitting together.

Medical knowledge only. Not for autonomous decision making. Check sources and use your clinical judgement.
Every tier shares a baseline: urgent head CT, head up 30 to 45 degrees, SpO2 above 94%, temperature under 38°C and SBP above 100 mmHg between ages 50 and 69, above 110 mmHg outside that band. Repeat the CT at six hours. Score E, V and M separately, after resuscitation and before sedation or paralysis.
Mortality tracks the tier: roughly 0.1% at 13 to 15, near 10% at 9 to 12, close to 40% at 8 or below. Mild cases image by Canadian CT Head Rule or NEXUS, though NSW ACI caps mild at 14 to 15 and leaves 13 for closer watch. Moderate means admission, serial GCS and neurosurgical review for hematoma, contusion or midline shift. Severe adds a definitive airway, full spinal precautions and an ICP monitor in salvageable patients with an abnormal CT (BTF Level IIB), targeting ICP at or below 22 mmHg and CPP 60 to 70 mmHg. Anyone at 12 or below goes to a top-level trauma center.
Tiering by sum score is under revision. The NIH-NINDS 2025 nomenclature initiative proposes four pillars instead: clinical assessment with pupillary reactivity, biomarkers, imaging and functional outcomes. Identical totals can hide very different pathophysiology.
