Emergency care refers to immediate medical attention given to someone who is experiencing a critical or life-threatening condition. This type of care is usually provided in emergency rooms at hospitals, but can also be administered by paramedics and other first responders in the field. Emergency care involves rapid assessment, diagnosis, and treatment to stabilize the patient's condition until they can receive further medical attention or undergo more extensive diagnostic tests. It may include procedures such as CPR, defibrillation, intravenous fluids, medications, and surgery, depending on the severity of the situation. The goal of emergency care is to prevent death or permanent harm to the patient's health until they can receive appropriate follow-up care from a physician.
