An asthma attack is exactly that - the muscles around the airways and the lining of the air passages tighten. Swelling reduces the amount of air that can pass through the airways and leads to a high-pitched, wheezing sound. Asthma attacks can become life-threatening if the airflow in the lungs becomes severely blocked.
Ambulatory surgery center. Ambulatory surgery centers (ASC), also known as outpatient surgery centers or same day surgery centers, are health care facilities where surgical procedures not requiring an overnight hospital stay are performed.
ASCs are not rural health clinics, urgent care centers or ambulatory care centers that provide diagnostic or primary health care services. ASCs treat only patients who have already seen a health care provider and selected surgery as the appropriate treatment for their condition. ASCs are not physicians' offices either.
