Iron lungs sit unused in an abandoned state hospital somewhere in the US. There are a handful of people left in the US who these machines, and now no company will provide parts or service for them. Yet these sit here, and probably still work. http://www.pprg.org/index.php?option=com_content=article=76%3Airon-lung-crisis=35%3Aresource-articles=58
Polio treatment- The Iron Lung - A metal chamber, with a sliding base upon which the patient is place, an electrically operated pump, a gauge and a valve are the chief parts of the outfit. The patient is placed on the sliding bed, shoved into the cabinet and the shield tightly locked. A rubber collar, which fits so snugly that almost no air can pass, is adjusted about the patient's neck. A switch is turned, and the cabinet begins its work.
once again, as I researched, I found a woman that lived in an iron lung until 2008. Dianne Odell had been confined to an iron lung for nearly 60 years. She was diagnosed with polio before the polio vaccine was invented. Odell lived in an iron lung because she had a severe case of polio – bulbar polio – which had left her paralyzed and unable to breathe on her own.
