Abstract
A vent for venting exhaust gases from a component of a respiratory therapy system. The vent may include a substrate having an inner surface and an outer surface. The vent may include at least one vent holeextending through the substrate and having a vent hole circumference. The vent hole may include an exhaust gas inlet at the inner margin of the substrate and an exhaust gas outlet at an outer margin of the substrate. The vent hole may include a sidewall extending between the exhaust gas inlet and the exhaust gas outlet. The exhaust gas inlet and the exhaust gas outlet have different diameters such that the sidewall of the vent hole is inclined at an angle of inclination between the exhaust gas inlet and the exhaust gas outlet. The angle of inclination of the inclined side wall of the vent is non-constant around the vent hole circumference.
