GCS

The Glasgow Coma Scale (GCS) is a clinical tool used to assess a patient's level of consciousness based on three criteria: eye opening, verbal response, and motor response, with scores ranging from 3 (deep coma) to 15 (fully alert). It is crucial in evaluating neurological status, guiding treatment decisions, and predicting outcomes in traumatic brain injury and other conditions affecting consciousness. A key association is its use in triaging patients with head injuries, where a lower GCS indicates a higher risk of complications.
