Question

respirator His lungs had been terribly damaged by decades of heavy smoking, and he'd been living on a respirator for the last year. ˈrɛspərˌeɪtər

Accepted Answer

(1) A device worn over the nose and mouth to filter out dangerous substances from the air. (2) A device for maintaining artificial respiration. Respiration means simply “breathing.” We usually come across the word in artificial respiration, the lifesaving technique in which you force air into the lungs of someone who's stopped breathing. Respirators can take several different forms. Scuba-diving equipment always includes a respirator, though it doesn't actually do the breathing for the diver. Medical respirators, which are used especially for babies and for emergency care and actually take over the job of getting oxygen into the lungs, are today usually called ventilators, so as to distinguish them from simple oxygen systems (which merely provide a steady flow of oxygen into the nostrils) and face masks
