The invention is related to a portable rebreathing system for closed rebreathing. In order to minimize consumption of oxygen during rebreathing mode while safeguarding correct oxygen concentration, oxygen is added into the breathing passage using staged addition of oxygen via at least three individual oxygen supply valves 51, 52, 53. The two first oxygen supply valves are calibrated nozzles where one nozzle 51 is constantly delivering a predetermined amount of oxygen during normal breathing and the second nozzle 52 adds more oxygen at a second predetermined amount when the person to be treated is breathing heavily. The third valve is only opened manually and delivers a short burst of oxygen that fills the rebreathing system and its counter lung within seconds.
