The iron lung used negative pressure ventilation (NPV), which “mimics natural breathing by creating negative pressure around the chest, causing the lungs to expand and pull in air,” explains ...
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 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 ...
