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.
Outpatient surgery allows a person to return home on the same day that a surgical procedure is performed. Outpatient surgery is also referred to as ambulatory surgery or same-day surgery. Outpatient surgery eliminates inpatient hospital admission, reduces the amount of medication prescribed, and uses a doctor's time more efficiently.
