machine kept the patient breathing, with the help of underpressure and overpressure. The whole body, except the head, was placed in a pressure chamber, where it was not possible to regulate how much air the patient received. Engstrom found that the iron lungs did not adequately ventilate patients with severe poliomyelitis.

Rows of iron lungs filled hospital wards at the height of the polio outbreaks of the 1940s and 1950s helping children, and some adults, with bulbar polio and bulbospinal polio. A polio patient with a paralyzed diaphragm would typically spend two weeks inside an iron lung while recovering. This

Engström was born on 1 September 1912 in
Oskarshamn to Carl Johan Engström and Judith Ringberg. He obtained is degree in medicine in 1941. He worked from 1941 at Stockholm Hospital for Infectious Diseases and started to work in the Swedish Air Force in 1956. He got his PhD in medicine at the
