MECHANICAL VENTILATION IN THORACIC SURGERY WITH A NEW PULMOFLATOR BY

MECHANICAL artificial respiration during thoracic surgery has been a theoretical ideal in the minds of many engaged in this field ever since the work of Crafoord (1938). Despite the fact that for some years now excellent machines to carry out this function have been on the market, they are still not in universal use. Many feel that the human hand is more informative and controllable than any machine so far invented (Esplen, 1952; Mushin and Rendell-Baker, 1953; Williams, 1954). Such coarse obstruction of the airway as may occur during thoracic surgery by secretions or by the kinking o
