The SERVO Ventilator 900 C/D/E consists of two sepa-­ rate units. The pneumatic unit comprises the gas conduction system with two pressure transducers, two flow transducers and two servo valves. Each transducer, continuously delivers its actual value to the electronic unit. The servo valves are used as CONTROLLING ­ELE­MENTS for the control of inspiratory and expiratory gas conduction. The electronic unit comprises three controlling systems, two for regulation of inspiration and one for regulation of expiration. The three controlling systems will be in use, one at a time, depending on the TIMING control and the se­lected ventilation MODE.
