Ventilator

Also known as a respirator, this machine pushes air into the lungs through a tube placed in the trachea (breathing tube). Ventilators are used when a person cannot breathe on his or her own, or cannot breathe effectively enough to provide adequate oxygen to the cells of the body or rid the body of carbon dioxide.
