    • A patient breathing system includes a ventilator that provides a driving gas flow to generate patient inspiration. The ventilator further includes a gas inlet for driving gas, the patient breathing system being connectable to a circle which includes an inspiratory hose and an expiratory hose connected to patient, through which circle expired gases can be circulated back to the patient. The circle further includes a fresh gas inlet, an arrangement for enabling the gas flow in a desired direction, a unit for removal of the exhaled carbon dioxide, and a ventilator port for the ventilator connection. The patient breathing system further includes an arrangement by which driving gas of the ventilator has been separated from the patient gases flowing in the circle.
    • 患者呼吸系统包括提供驱动气流以产生患者吸气的呼吸机。 所述呼吸机还包括用于驱动气体的气体入口,所述患者呼吸系统可连接到包括吸气软管和连接到患者的呼气软管的圆圈,通过该呼气软管将呼出的气体循环回患者。 该圆形还包括新鲜气体入口,用于使气体沿所需方向流动的装置,用于除去呼出的二氧化碳的单元和用于呼吸机连接的呼吸机端口。 患者呼吸系统还包括通气机的驱动气体已经与在圆圈中流动的患者气体分离的装置。
