n.
1. a device used to maintain the breathing movements of paralysed patients. In the positive-pressure respirator air is blown into the patient's lungs via a tube passed either through the mouth into the trachea or through a tracheostomy. Air is released from the lungs when the pressure from the respirator is relaxed. The iron lung is a type of respirator in which the patient is enclosed, except for the head, in an airtight container in which the air pressure is decreased and increased mechanically. This draws air into and out of the lungs, through the normal air passages. The cuirass respirator works on a similar principle, but leaves the limbs free.
2. a face mask for administering oxygen or other gas or for filtering harmful fumes, dust, etc. See also artificial respiration.
