Allow oxygen to fill up an area of an enclosed space in order for air to be pumped via vents into other areas of your base. Currently if you setup a room with an oxygen distributor the area of oxygen is limited to the radius of the device even though the oxygen would typically keep building up to fill the room. Maybe even have a max pressure calculated from the amount of area the oxygen has to fill up. The bigger the room or rooms would require more oxygen devices to keep the pressure up.
