[Artificial ventilation with the servo-ventilator 900 (author's transl)]

The use of artificial ventilation in the treatment of seriously ill or severely injured patients demands extensive knowledge on the part of the physician of the physiological and pathological effects of ventilation. In addition, it is required that the manufacturers develop ventilators able to meet there special demands. During the last two years the Servo-Ventilator 900 has been in use in our intensive care unit. During this period we were very impressed by its versatile applicability. The use of this apparatus however more than ever before requires the knowledge of breathing mechanisms and their pathophysiological consequences. The various flow- and breathing-rate-patterns combined with the exact electronic control of the respiratory make possible subtle adjustments--to the required ventilation pattern.
