Polio and the Evolution of Respiratory Support
Poliomyelitis, once a widespread and feared disease, caused paralysis and respiratory failure in many children and adults during the first half of the 20th century. The development of the Salk and Sabin vaccines in the 1950s drastically reduced new cases in the U.S., leading to a decline in reliance on mechanical ventilators like the iron lung.
By the late 20th century, the use of the iron lung had become rare, with only a handful of survivors needing such support. Martha Lillard’s reliance on the device made her a symbol of the disease’s historical toll. Her death marks the last known case of a person in the U.S. dependent on this technology, which was once a common treatment for polio-induced paralysis.
“Martha Lillard’s passing symbolizes the closing chapter on a chapter of medical history that shaped the lives of thousands.”
