GCS Calculator (Glasgow Coma Scale)

The GSC calculator helps you find the Glasgow Coma Scale of your patient.

To calculate GSC, select one of the eye response options, i.e., does not open eyes, opens eyes in response to pain, opens eyes in response to voice, or opens eyes spontaneously.

Choose one of the verbal response options. These include whether the patient makes the sound, makes no sound, speaks words, looks confused or disoriented, or looks oriented and converses normally.

The motion response options include whether the patient makes no movements, extension to painful stimuli, abnormal extension to painful stimuli, flexion, localizes to painful stimuli, or obeys commands.

In case you do not know, the Glasgow Coma Scale (GCS) objectively measures consciousness in acute medical and trauma patients. The measure evaluates patients’ eye-opening, motor, and vocal responses.

The Glasgow Coma Scale has three components: best eye reaction (E), best verbal response (V), and best motor response (M) (M).

The response levels in the Glasgow Coma Scale components are scored from 1 for no response to typical values of 4 (Eye-opening response), 5 (Verbal response), and 6. (Motor response)

Hence, the overall Coma Score ranges from three to fifteen, with three being the worst and fifteen being the best.
