What it is

Drinker and Shaw, professors of industrial hygiene at Harvard, built a negative-pressure respirator -a sealed cylinder from which only the patient's head protrudes- that forces breathing when the respiratory muscles fail. It was first used on a patient on 12 October 1928, at Boston Children's Hospital.

Wikidata dates the milestone to 1927, the year of the first prototypes and tests; the first clinical use on a person was on 12 October 1928.

What it led to

  • Mass treatment of polio-induced respiratory paralysis (1940s-1950s)
  • Later development of positive-pressure ventilators
