When negative pressure is released, the chest naturally ...

Joe Middleton looks at the life of Paul Alexander, who spent 70 years in an iron lung before passing away at 78

They often started out as one building. And look at that iron lung.
This machine came to be known colloquially as the Iron lung, which went through many iterations of development. The use of the iron lung became widespread during the polio epidemic of the 1900s. Early ventilators were control style with no support breaths integrated into them and were limited to an inspiration to expiration ration of 1:1.
