When was the first iron lung invented?
The first of these devices to be widely used however was developed in 1928 by Drinker and Shaw of the United States. The iron lung, often referred to in the early days as the "Drinker respirator", was invented by Philip Drinker (1894–1972) and Louis Agassiz Shaw Jr., professors of industrial hygiene at the Harvard School of Public Health. The machine was powered by an electric motor with air pumps from two vacuum cleaners. The air pumps changed the pressure inside a rectangular, airtight metal box, pulling air in and out of the lungs.
What causes a patient to breathe in a cylinder?
To cause the patient to inhale, air is pumped out of the cylinder, causing a slight vacuum, which causes the patient's chest and abdomen to expand (drawing air from outside the cylinder, through the patient's exposed nose or mouth, into their lungs).
Is iron lung a success?
It proved a success and soon superseded the iron lung throughout Europe. The iron lung now has a marginal place in modern respiratory therapy. Most patients with paralysis of the breathing muscles use modern mechanical ventilators that push air into the airway with positive pressure.
introduction
In the early 1900s, the human population around the world faced the poliomyelitis epidemic. This deadly disease, taking thousands of innocent lives, showed no mercy to its victims. Polio was a viral infection that attacked the whole body, primarily the nervous system, which often led to paralysis and death.
Background and How the Iron Lung Works
The effects of paralysis on a patient’s lungs called for a device that assisted breathing. The iron lung was created by Philip Drinker and Louis Agassiz Shaw Jr in the late 1920s (Chapman, 2015; Slutsky, 2015). The iron lung was a bulky metal tank that weighed 650 pounds.

Overview
An iron lung is a type of negative pressure ventilator (NPV), a mechanical respirator which encloses most of a person's body, and varies the air pressure in the enclosed space, to stimulate breathing. It assists breathing when muscle control is lost, or the work of breathing exceeds the person's ability. Need for this treatment may result from diseases including polio and botulism and certai…
Design and function
The iron lung is typically a large horizontal cylinder, in which a person is laid, with their head protruding from a hole in the end of the cylinder, so that their full head (down to their voice box) is outside the cylinder, exposed to ambient air, and the rest of their body sealed inside the cylinder, where air pressure is continuously cycled up and down, to stimulate breathing.
Method and use
Humans, like most mammals, breathe by negative pressure breathing: the rib cage expands and the diaphragm contracts, expanding the chest cavity. This causes the pressure in the chest cavity to decrease, and the lungs expand to fill the space. This, in turn, causes the pressure of the air inside the lungs to decrease (it becomes negative, relative to the atmosphere), and air flows into the lungs from the atmosphere: inhalation. When the diaphragm relaxes, the reverse happens an…
Invention and early use
In 1670, English scientist John Mayow came up with the idea of external negative pressure ventilation. Mayow built a model consisting of bellows and a bladder to pull in and expel air. The first negative pressure ventilator was described by British physician John Dalziel in 1832. Successful use of similar devices was described a few years later. Early prototypes included a hand-operated bellow…
Modern development and usage
Polio vaccination programs have virtually eradicated new cases of poliomyelitis in the developed world. Because of this, and the development of modern ventilators, and widespread use of tracheal intubation and tracheotomy, the iron lung has mostly disappeared from modern medicine. In 1959, 1,200 people were using tank respirators in the United States, but by 2004 that number had decreased to just 39.
