An emergency department (ED) is a specialized area in a hospital that provides immediate medical care for urgent health issues. It is equipped to handle a wide range of emergencies, including injuries, illnesses, and life-threatening conditions. Patients are typically seen on a first-come, first-served basis, but those with more severe conditions may be prioritized. The ED is staffed by a team of healthcare professionals, including doctors, nurses, and support staff, who are trained to respond quickly to critical situations. Common reasons for visiting the ED include chest pain, severe bleeding, and difficulty breathing. The goal is to stabilize patients and determine the next steps for treatment.
