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.
From Wikipedia, the free encyclopedia. Ambulatory care or outpatient care is medical care provided on an outpatient basis, including diagnosis, observation, consultation, treatment, intervention, and rehabilitation services. This care can include advanced medical technology and procedures even when provided outside of hospitals.
