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 ]
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 ...
This machine came to be known colloquially as the Iron lung, which went through many iterations of development. The use of the iron lung became widespread during the polio epidemic of the 1900s. Early ventilators were control style with no support breaths integrated into them and were limited to an inspiration to expiration ration of 1:1.
In 2015 his iron lung he’d lived in for most of his life started to break, but spare parts for the machine - which hadn’t been widely in circulation since the 1960s - were not readily available.
The iron lung cycles air pressure inside the machine to facilitate inhalation and exhalation. In the museum’s iron lung, the patient is represented by a doll. ... It has a hand-powered static ...
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 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 ...
