  1. Though these rules are not reliable enough for practical use, they can contain pattern information which may be of interest to physicians. FSBP represents initial blood pressure; ISS stands for Injury Severity Score; EDGCSTOTAL is the total Glasgow Coma Score recorded in the emergency department; EDRTS is the Emergency Department Revised Trauma Score; ARDS stands for Acute Respiratory Distress Syndrome; Cg for coagulopathy.
