When a person cannot breathe on their own or maintain an open airway, they may require intubation and the use of an emergency ventilator. Intubation is the process of inserting a breathing tube through the mouth and into the airway. An emergency ventilator also known as a respirator or breathing machine is a medical device that provides oxygen through the breathing tube.
An emergency ventilator may be used to assist with breathing during anesthesia or sedation for an operation or when a person is severely ill or injured and cannot breathe on their own. The emergency ventilator pushes air into the lungs to deliver a breath, then allows the air to come back out, just as the lungs would do if they were able to.
