Bjørn Aage Ibsen dating history

Details

Bjørn Aage Ibsen (August 30, 1915 – August 7, 2007) was a Danish anesthetist and founder of intensive-care medicine. He graduated in 1940 from medical school at the University of Copenhagen and trained in anesthesiology from 1949 to 1950 at the Massachusetts General Hospital, Boston. He became involved in the 1952 poliomyelitis outbreak in Denmark, where 2722 patients developed the illness in a 6-month period with 316 suffering respiratory or airway paralysis. Treatment had involved the use of the few negative pressure ventilators available, but these devices, while helpful, were limited and did not protect against aspiration of secretions. After detecting high levels of CO2 in blood samples and inside a little boy's lung, Ibsen changed management directly. He instituted protracted positive pressure ventilation by means of intubation into the trachea, and enlisting 200 medical students to manually pump oxygen and air into the patients lungs. In this fashion, mortality declined from 90% to around 25%. Patients were managed in 3 special 35 bed areas, which aided charting and other management.
