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 ...

Emerson continued to make improvements to the iron lung, adding a quick opening and closing function, an improved pressure gauge, and emergency hand operation. His final improvement was the addition of a transparent positive pressure dome, allowing ventilation when the chamber was opened to care for the patient. [2]
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 ...
