Abstract
A breathing mask including a vent system for ventilating the mask, a detector for providing respiration data of a user and located for sensing at least one physical property of air inside the breathing mask when worn by a user and a controller configured to activate the vent system based on the respiration data. The controller may be configured to predict future respiration data based on historic respiration data of at least one earlier detected inhaling or exhaling cycle, determine whether a future inhaling or exhaling cycle will occur based on predicted future respiration data and activate the vent system before the determined future inhaling or exhaling cycle commences.
