ABSTRACT:
A ventilator has an inspiration section for supplying respiratory gas to a respiratory system of a patient and an expiration section for conveying respiratory gas from the respiratory system is described. If the patient spontaneously inhales during a controlled inspiration phase, the inspiration section and expiration section will be controlled to allow a spontaneous exhalation during a specific period of time within the inspiration phase. The patient thus will be able to respirate in a natural way even during controlled respiration, resulting in increased comfort and increased motivation for increasing the spontaneous respiration rate. If an insufficient tidal volume or minute volume is supplied during the controlled and spontaneous part of the inspiration phase, the inspiration phase will commence immediately after the spontaneous exhalation for supplying a remaining part of the set tidal volume.
