Typical<unk>  room at Level I<unk>  A<unk>  (or<unk> e) is a hospital equipped and staffed to provide care for patients suffering from major<unk> tic injuries such as falls, motor vehicle collisions, or gunshot wounds. A<unk>  may also refer to an emergency department (also known as a "casualty department" or "accident and emergency") without the presence of specialized services to care for victims of major<unk> . In the United States, a hospital can receive<unk>  status by meeting specific criteria established by the American College of Surgeons (ACS) and passing a site review by the Verification Review Committee. Official designation as a<unk>  is determined by individual state law provisions.<unk> s vary in their specific capabilities and are identified by "Level" designation: Level I (Level-1) being the highest and Level III (Level-3) being the lowest (some states have five designated levels, in which case Level V (Level-5) is the lowest). The highest levels of<unk> s have access to specialist medical and nursing care, including emergency medicine,<unk>  surgery, critical care, neurosurgery, orthopedic surgery, anesthesiology, and radiology, as well as a wide variety of highly specialized and sophisticated surgical and diagnostic equipment. Lower levels of<unk> s may be able to provide only initial care and stabilization of a<unk> tic injury and arrange for transfer of the patient to a higher level of<unk>  care. The operation of a<unk>  is often expensive and some areas may be underserved by<unk> s because of that expense. As there is no way to schedule the need for emergency services, patient traffic at<unk> s can vary widely. A<unk>  may have a helipad for receiving patients that have been airlifted to the hospital. In some cases, persons injured in remote areas and transported to a distant<unk>  by helicopter can receive faster and better medical care than if they had been transported by ground ambulance to a closer hospital that does not have a designated<unk> .
