An iron lung is a type of negative pressure ventilator, a mechanical respirator which encloses most of a person's body and varies the air pressure in the enclosed space to stimulate breathing. [ 1 ] [ 2 ] It assists breathing when muscle control is lost, or the work of breathing exceeds the person's ability. [ 1 ]
NPVs do not work well if patient's lung compliance is decreased, or their lung resistance is increased. [2] They result in a greater vulnerability of the airway to aspiration, such as inhalation of vomit or swallowed liquids, than with intermittent positive pressure ventilation. [1] They exacerbate obstructive sleep apnea. The device is not ...
Emerson's father encouraged him to work on an artificial respirator after noticing the beginning of a polio epidemic. 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.
The last man to live in an iron lung died in Dallas on Monday. Paul Alexander, 78, spent more than 70 years confined to an iron lung after contracting polio as a child in 1952.
The history of mechanical ventilation begins with various versions of what was eventually called the iron lung, a form of noninvasive negative-pressure ventilator widely used during the polio epidemics of the twentieth century after the introduction of the "Drinker respirator" in 1928, improvements introduced by John Haven Emerson in 1931, [5 ...

The museum’s iron lung, which still functions, operated in the Sacramento County Hospital, LaPerriere said. “The arms were in the iron lung, so the patient could not lift up a glass if they ...
In the iron lung by means of a pump, the air is withdrawn mechanically to produce a vacuum inside the tank, thus creating negative pressure. [41] This negative pressure leads to expansion of the chest, which causes a decrease in intrapulmonary pressure, and increases flow of ambient air into the lungs.
