The Iron Lung | Science Museum
The iron lung was large, cumbersome and very expensive, but it saved the lives of thousands of polio victims.
www.sciencemuseum.org.ukHere’s a concise update on the latest around iron lungs.
- The iron lung is now largely obsolete for routine use, with modern ventilators and noninvasive ventilation methods dominating care for respiratory failure. However, a small number of individuals who relied on iron lungs in the past remain, and there’s ongoing historical interest and occasional new prototypes inspired by the device.[2][6]
- In the United States, as of recent years, a few long-term users have still depended on iron lungs, with reports noting the remaining users and concerns about replacement parts and maintenance as they age. This includes ongoing coverage of individuals who continued to rely on the device years after polio outbreaks.[8][2]
- The COVID-19 era spurred renewed discussion about simple, scalable respiratory support options, and a few groups explored modernized or simplified iron lung concepts to address ventilator shortages, though these are not standard clinical practice and are primarily research or novelty efforts.[1][4]
Illustrative context
- Historical role: Polio outbreaks in the 20th century made iron lungs a life-saving technology before widespread vaccination and modern ventilators were available. They work by creating negative pressure to expand the chest and draw air into the lungs, with the patient’s head remaining outside the sealed chamber.[6]
- Notable recent reference: Media reports in 2020–2021 highlighted individuals who still relied on iron lungs, underscoring supply, maintenance, and quality-of-life considerations for lifelong use.[2]
