Iron Lung
Filed under: add to del.icio.us
An iron lung, or negative pressure ventilator, is an airtight metal tank that encloses all of the body except the head and forces the lungs to inhale and exhale through regulated changes in air pressure. It found its most famous use in the mid-1900s when victims of polio, stricken with paralysis and unable to breathe, were placed in these steel chambers to survive. What treatment methods have, for the most part, replaced the iron lung?
