An 'iron lung' is a machine that enables a patient to breathe, when the patient's respiratory muscles are paralyzed. It was invented by Dr Dinker and associates in 1928. A more efficient unit was made several years later. It is most famous for use during the polio epidemics in the 1940s and 50s, when literally thousands of people, many children, had polio. The device works by placing the patient inside, with only the head outside the machine. The machine then creates alternating negative and positive pressure to create 'breathing' for the patient. The negative pressure inside the unit inflates the lungs, and the positive pressure deflates them- ie inspiration and expiration. For more information, go to Wikipedia Encyclopedia on-line, and type in 'iron lung' in the search field.
It was an old style machine that alternated the pressure inside this cylindrical machine. The changing pressure helped a person breath. Higher pressure pushed air out of a patients lungs, then the pressure would lower helping the patient inhale. The patients head was left outside the machine.
It is still used, but now it is called a Respirator.
My Iron Lung was created in 1993.
