A patient breathing system comprising a ventilator (2) providing driving gas flow to generate patient inspiration, the ventilator further comprising a gas inlet (2a) for driving gas, the patient breathing system being connectable to a circle comprising an inspiratory hose (3) and an expiratory hose (4) connected to patient, through which circle expired gases can be circulated back to the patient (1). The circle further comprises a fresh gas inlet (6), an arrangement (7, 8) for enabling the gas flow in a desired direction, a unit (10) for removal of the exhaled carbon dioxide, and a ventilator port (9) for the ventilator connection. The patient breathing system further comprises an arrangement (11) by which driving gas of the ventilator (2) has been separated from the patient gases flowing in the circle. The arrangement (11) separating the driving gas of the ventilator (2) and the patient gases flowing in the circle, is formed by an extended gas pathway (12) between the circle and the ventilator.
