An ED requires different equipment and different approaches than most other hospital divisions. Patients frequently arrive with unstable conditions, and so must be treated quickly. They may be unconscious, and information such as their medical history, allergies, and blood type may be unavailable. ED staff are trained to work quickly and effectively even with minimal information.

ED staff must also interact efficiently with pre-hospital care providers such as [[EMTs]], [[paramedics]], and others who are occasionally based in an ED. The pre-hospital providers may use equipment unfamiliar to the average physician, but ED physicians must be expert in using (and safely removing) specialized equipment, since devices such as [[military anti-shock trousers]] ("MAST") and [[traction splint]]s require special procedures. Among other reasons, given that they must be able to handle specialized equipment, physicians can now specialize in emergency medicine, and EDs employ many such specialists.

ED staff have much in common with ambulance and fire crews, [[combat medic]]s, [[search and rescue]] teams, and [[disaster response]] teams. Often, joint training and practice drills are organized to improve the coordination of this complex response system. Busy EDs exchange a great deal of equipment with ambulance crews, and both must provide for replacing, returning, or reimbursing for costly items.

Cardiac arrest and major trauma are relatively common in EDs, so [[defibrillator]]s, automatic ventilation and [[Cardiopulmonary resuscitation|CPR]] machines, and bleeding control dressings are used heavily. Survival in such cases is greatly enhanced by shortening the wait for key interventions, and in recent years some of this specialized equipment has spread to pre-hospital settings. The best-known example is defibrillators, which spread first to ambulances, then in an [[Automated external defibrillator|automatic version]] to police cars and fire apparatus, and most recently to public spaces such as airports, office buildings, hotels, and even shopping malls.

Because time is such an essential factor in emergency treatment, EDs typically have their own diagnostic equipment to avoid waiting for equipment installed elsewhere in the hospital. Nearly all have radiographic examination rooms staffed by dedicated [[radiographer]]s, and many now have full radiology facilities including CT scanners and ultrasonography equipment. Laboratory services may be handled on a priority basis by the hospital lab, or the ED may have its own "STAT Lab" for basic labs (blood counts, blood typing, toxicology screens, etc.) that must be returned very rapidly.
