The Glasgow Coma Scale provides a framework for describing the state of a patient in terms of three aspects of responsiveness: eye opening, verbal response, and best motor response, each stratified according to increasing impairment.

The Glasgow Coma Score is an artificial index; obtained by adding scores for the three responses. The notation for the score was derived from the extended scale, incorporating the distinction between normal and abnormal flexion movements, producing a total score of 15. The score ranges from 3 to15. This score can provide a useful single figure summary and a basis for systems of classification, but contains less information than a description separately of the three responses.

The GCS calculator is part of the CardioMath for iPhone/iPod Touch with over 70 commonly used formulas in cardiovascular medicine. It is designed to assist physicains, nurses, pharmacists, technologists, technicians, and other allied health professional to perform essential day-to-day calculations accurately and effectively.
