What does the Glasgow Coma Scale (GCS) assess?

The Glasgow Coma Scale (GCS) specifically evaluates a person's level of consciousness following a head injury or other medical condition that may impair brain function. It is a clinical tool that provides a score based on three components: eye opening, verbal response, and motor response. Each of these components is scored individually and the total score helps to determine the severity of impairment, ranging from complete composure to deep unconsciousness.

This assessment is especially critical in emergency medical settings, as it aids in quickly determining a patient's neurological status and can guide treatment decisions and transport priorities. The scale thus serves as a standardized method for paramedics and medical professionals to communicate a patient’s consciousness level effectively.
