An Emerson iron lung. The patient lies within the chamber, which when sealed provides an oscillating atmospheric pressure. This particular machine was donated to the Centers for Disease Control and Prevention Museum by the family of polio patient Barton Hebert of Covington, Louisiana, who had used the device from the late 1950s until his death in 2003.
Emerson thus began his work on the iron lung in the early 1930s, improving the design of the Drinker lung. Completed in July 1931, Emerson's lung was quieter, lighter, more efficient, and cheaper. With a $1000 price tag, it sold for less than half the price of Drinker's make.
In most NPVs (such as the iron lung in the diagram), the negative pressure is applied to the patient's torso, or entire body below the neck, to cause their chest to expand, expanding their lungs, drawing air into the patient's lungs through their airway, assisting (or forcing) inhalation. When negative pressure is released, the chest naturally ...
