Figure Legend:
The physician is shown here examining a tank respirator, also known as an iron lung, during a polio epidemic. The iron lung encased the thoracic cavity externally in an air-tight chamber. The chamber was used to create a negative pressure around the thoracic cavity, thereby causing air to rush into the lungs to equalize intrapulmonary pressure.
