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]
The Both respirator, also known as the Both Portable Cabinet Respirator, was a negative pressure ventilator (more commonly known as an "iron lung") invented by Edward Both in 1937. Made from plywood , the respirator was an affordable alternative to the more expensive designs that had been used prior to its development, and accordingly came into ...
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.

This sentence had two fundamental errors: It implied that all "negative pressure ventilators" were "iron lungs," when, in fact, iron lungs are just one type of NPV. There are several others, some itemized in the ...
