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 centers. Definition. Ambulatory surgery centers (ASCs) are medical facilities that specialize in elective same-day or outpatient surgical procedures. They do not offer emergency care. The word ambulatory comes from the Latin verb ambulare , which means to walk..
Ambulatory strictly means the ability to walk but in the context of surgery, it refers to patients who are able to leave the hospital the same day as the surgery, without being admitted. Ambulatory surgery is referred to by other names, commonly called minimally invasive surgery, outpatient surgery or same day surgery.
