Polio ward with children in iron lungs. Iron lungs are artificial respiration devices used to treat patients that are unable to breathe due to paralysis. They were used most extensively in the mid 1900s to treat patients with polio (poliomyelitis),a viral disease that infects the central nervous system causing muscle weakness and paralysis. Vaccination against polio started in 1955 and by 1991 the disease had been eradicated from the Western world. Photographed in the USA | |
