Zusammenfassung:	A cushion for use in providing a regimen of respiratory therapy to a patient includes a base that defines a main cavity therein an aperture for receiving a flow of breathing gas. A pair of nasal pillows each extend from the base, each having a cone-shaped head that tapers inward and upward from a base portion, that extends directly from the base, to a top opening. Each head is formed to engage an inner portion of a nare of the patient. Each head defines a passage extending between the main cavity and the top opening for further conveying the flow of breathing gas from the main cavity to a nasal passage of the patient. Each base portion includes an inner edge positioned near the center of the cushion that merges with the hollow base and an opposite outer edge spaced upward from an outer surface of the hollow base.
