Positive pressure check (for masks without exhalation valve): Cover the mask completely with both hands, and then exhale, the mask should bulge slightly. If air overflows from the edge of the mask, it means that it is not worn properly. Please re-adjust the position of the mask or adjust the metal nose bridge. 9.
