Negative Pressure Ventilator, Iron Lung


Made of stainless steel, and still in good working order, this Emerson respirator, more commonly referred to as an "iron lung" was used by polio patients whose ability to breath was paralyzed due to this crippling viral disease. Polio patients of the 1950's depended on these devices to breath after being paralyzed with this devastating virus. This iron lung was donated to the CDC's Global Health Odyssey by the family of polio patient Mr. Barton Hebert of Covington, Louisiana, who'd used the device from the late 1950s until his death in 2003. The chamber is used to create a negative pressure around the thoracic cavity, thereby, causing air to rush into the lungs to equalize intrapulmonary pressure. J. H. Emerson Co. manufactured this type of life saving respirator in the 1930s, but in the 1950's and '60's, the invention of portable ventilators made iron lungs obsolete. By 1970, J. H. Emerson Co. ceased manufacturing this apparatus, but many still depend on such mechanical ventilation systems on a daily basis.
