Bjørn Ibsen (1915-2007) developed the first intensive care unit in the Kommunehospitalet at Copenhagen in 1953 after success in manual ventilation of polio patients the previous year. His first case was a 12 year girl. He is the father of intensive care and had made his name the year before when he reduced mortality from type II respiratory failure in polio from 80% to 25%. He proposed that the patients be treated by tracheostomy and positive pressure mechanical respiration in order to achieve better ventilation than with an iron lung. This had other implications to enhance patient survival.
