A CPAP or other ventilation system includes a mask, a flow generator, a positive or high pressure line to provide positive or high pressure air from the flow generator to the mask and a vacuum or return line provided to actively extract exhaled gas from the breathing chamber and/or the air delivery conduit of the mask. The vacuum or return line includes a vent outlet preferably positioned remote from the mask.
