What is the primary function of the Glasgow Coma Scale?

The primary function of the Glasgow Coma Scale is to assess the level of consciousness in a patient. This scale provides a systematic way to evaluate a patient's responsiveness through three components: eye opening, motor response, and verbal response. Each component is scored, and the total score helps determine the severity of a patient's brain injury and their level of consciousness.

The scale is widely utilized in clinical settings, especially in emergency medicine and neurology, as it aids healthcare professionals in quickly identifying changes in a patient's condition, which is critical for effective treatment and monitoring. By quantifying the level of consciousness, it allows for better communication among medical staff regarding a patient's status and facilitates decisions about further interventions.
