Which feature of the Glasgow Coma Score is not evaluated?

The Glasgow Coma Scale (GCS) is a widely used tool for assessing a patient's level of consciousness and neurological functioning, primarily following a head injury. It evaluates three key areas: eye-opening responses, verbal responses, and motor responses. Each area is scored to provide a comprehensive overview of the patient's condition.

Cardiac function, however, is not a component of the Glasgow Coma Score. The GCS specifically focuses on how a patient responds to stimuli in those three areas, which are crucial for assessing consciousness and neurological status. Cardiac function pertains to the operations of the heart and circulatory system, which fall outside the scope of what the GCS measures. It is critical for clinicians to differentiate between assessments of neurological responsiveness and physiological functions like cardiac health to provide the most effective patient care.
