  1. Though these rules are not reliable enough for practical use, they can contain pattern information which may be of interest to physicians. Cg stands for coagulopathy; MI for myocardial infarction; ARDS for Acute Respiratory Distress Syndrome; EDRTS for Emergency Department Revised Trauma Score; ISS for Injury Severity Score; ID for Insulin-Dependent.
