Whereas the iron lung used NPV to facilitate airflow in patients, today’s ventilators use positive pressure ventilation (PPV), Mendez notes. The iron lung was less invasive than modern ...
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 jacket ventilator, also known as a poncho or raincoat ventilator, is a lighter version of the iron lung or the cuirass ventilator, constructed of an airtight material (such as plastic or rubber) arranged over a light metal or plastic frame, or screen, and depressurized and repressurized by a portable ventilator.

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.
The polio survivor spent more than 70 years being kept alive by the medical device.
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 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 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 ...
