This document outlines an emergency room (ER) simplified protocol for selecting and prioritizing ER cases. It provides guidelines for initial assessment and management of common ER presentations including hypoxia, hypertension, hypotension, tachycardia, bradycardia, hypoglycemia, hyperglycemia, abdominal pain, chest pain, anemia, and anuria/retention. Based on initial vitals and screening labs, patients are triaged to the resuscitation room, observation room, outpatient clinic, or referral to appropriate specialty services for continued care and management. The goal is good selection and prioritization of emergency cases as well as qualified dealing with urgent conditions through stabilization and specialty referral.
