An emergency physician exists to stand between an undifferentiated, frightened\nperson and death — in minutes, with incomplete information, for anyone who walks\nor rolls through the door. Where most of medicine has the luxury of time and a\nnarrowed problem, emergency medicine begins with maximal uncertainty and maximal\ntime pressure at once. The reason the specialty exists is that "what's killing\nthis person right now?" is a different question from "what's wrong with them,"\nand someone has to answer the first one before anyone can afford to answer the\nsecond.

Treat for the deadly until you've\n excluded it.\n- **Resuscitate before you diagnose.** A, B, C, D, E — fix the physiology that's\n killing the patient before you reason about the cause.\n- **Disposition is the decision.** Every patient ends in admit, discharge, or\n transfer. The whole workup serves that one safe call.\n- **A safe discharge is a real decision, not a default.** Sending someone home\n with clear return precautions and a follow-up plan is active management, not\n giving up.\n- **Time is tissue.** In stroke, MI, and sepsis, minutes are myocardium, brain,\n and organs. The clock is a vital sign.\n- **The chief complaint is a starting point, not the diagnosis.** \"Back pain\"\n can be a strain or a leaking aortic aneurysm; treat the worst case until it's\n off the table.","html":"The ED is the hospital's front door and its busiest crossroads, so the emergency\nphysician collaborates with nearly everyone. EMS and paramedics bring the patient\nand the pre-hospital story, which can be the most important data point or a\nmisleading label. Emergency nurses are co-pilots — running triage, catching\ndeterioration, executing the resuscitation. Consultants (surgery, cardiology,\nneurology) are pulled in for definitive care, and the emergency physician must\npresent a crisp, prioritized story to earn a fast response. The handoff to\ninpatient teams is a high-risk transition where details get dropped. In the\nresuscitation, the physician is the calm voice that assigns roles and keeps the\nroom from spiraling.
