NOTE: The results by this representation does not agree with the nomogram.
Parameters:
(1) emergency surgery
(2) hemoglobin in g/dL, over range from 4 to 16
(3) serum BUN in mg/dL, over range from 10 to 610
(4) Glasgow Coma Score (GCS, from 3 to 15)
(5) systolic blood pressure in mm Hg, over range from 30 to 260
(6) respiratory rate in breaths per minute, over range from 4 to 40
