Abstract
A mask system includes a mask component including one or more openings for gas washout and a vent component provided to the mask component. The vent component includes one or more tracks or grooves along its outer surface adapted to guide gas washout. The vent component is adapted to cover the one or more openings in the mask component so that gas washout escapes along the one or more tracks or grooves between an outer surface of the mask component and the vent component.
