A device (2) for the dosing of a dry additive gas into a breathing gas in a ventilator system (4), which ventilator system (4) comprises a tubing system (10,12,14) connectable by means of a distal end to a patient (6), and which device comprises a dosing tube (22) connectable to the tubing system (10,12,14) for dosing to the distal end of the tubing system (10,12,14) is disclosed. A simple and safe moistening of the dry additive gas is achieved through the dosing tube (22) being comprised of a tube section (22) having a moisture permeable contact surface, adapted to be connected to the distal end of the tubing system (10,12,14), in contact with moisture from exhaled breathing gas, whereby the dry additive gas is moistened before dosing. <IMAGE>
