A patient interface that reliably and comfortably seals a user's face by providing an oral-nasal mask that includes an integrated nasal interface. The patient interface includes a seal member having an oral cushion portion configured to surround the user's mouth and a nasal interface portion that provides an interface with the user's nose. The seal member, including the oral cushion portion and the nasal interface portion, is a unitary member. Finally, the nasal interface portion remains below the bridge of the nose.

1. A patient interface comprising: (a) a seal member adapted to contact a face of a user to provide a sealed interface with such a user, wherein the seal member comprises: (1) an oral cushion portion adapted to provide a sealed interface with such a user, wherein a sealing area of the oral cushion portion surrounds at least a portion a mouth of such a user, and wherein a first opening is defined in the oral cushion portion, the first opening being generally disposed in a first plane,(2) a nasal interface portion adapted to provide a sealed interface with such a user, wherein a sealing area of the nasal interface portion surrounds at least a portion of a nares of such a user, wherein a second opening is defined in the nasal interface portion, the second opening being generally disposed in a second plane, and wherein the first plane and the second plane are disposed at an angle with respect to one another, and(3) a web of material disposed between the first opening and the second opening;(b) a faceplate, wherein the seal member is operatively attached to the faceplate, wherein the faceplate and the seal member defines a chamber, and wherein the first opening and the second opening provide access to the chamber; and(c) a protrusion that extends from nasal interface portion, and wherein the protrusion is sized and configured that the protrusion is bounded at its upper extremity by a lower end of a nose of such a user responsive to the patient interface device being donned by a user. 2. The patient interface of claim 1, further comprising a pleat that at least partially surrounds a perimeter of the oral cushion portion. 3. The patient interface of claim 2, wherein the oral cushion portion includes a first sidewall disposed on a first each side of a face of a user and a second sidewall disposed on a second each side of a face of a user opposite the first side responsive to the patient interface being donned by a user, wherein the pleat includes a first pleat disposed in the first sidewall and a second pleat disposed in the second sidewall, and wherein the first pleat is separate from the second pleat. 4. The patient interface of claim 1, further comprising a headgear coupled to the faceplate. 5. The patient interface of claim 1, wherein the seal member is a unitary structure such that the oral cushion portion, the nasal interface portion, and the web of material are defined from a common material and are integral with one another. 6. A patient interface comprising: (a) a seal member adapted to contact a face of a user to provide a sealed interface with such a user, wherein the seal member comprises: (1) an oral cushion portion adapted to provide a sealed interface with such a user, wherein a sealing area of the oral cushion portion surrounds at least a portion a mouth of such a user, and wherein a first opening is defined in the oral cushion portion,(2) a nasal interface portion adapted to provide a sealed interface with such a user, wherein a sealing area of the nasal interface portion surrounds at least a portion of a nares of such a user such that the nasal interface portion defines a cavity adapted to receive a bottom of a user's nose responsive to the patient interface device being donned by a user, wherein a second opening is defined in the nasal interface portion proximate to a bottom of the cavity, and(3) a web of material disposed between the first opening and the second opening; and(b) a faceplate, wherein the seal member is operatively attached to the faceplate, wherein the faceplate and the seal member defines a chamber, and wherein the first opening and the second opening provide access to the chamber. 7. The patient interface of claim 6, wherein the nasal interface portion includes a pair of nasal pillows disposed with the cavity. 8. The patient interface of claim 6, wherein the second opening is sized and configured such that both nares of a user communicate with the chamber via the second opening responsive to the patient interface device being donned by a user. 9. The patient interface of claim 6, wherein the nasal interface portion comprises a protrusion that extends from the nasal interface portion, and wherein the protrusion is sized and configured that the protrusion is bounded at its upper extremity by a lower end of a nose of such a user. 10. The patient interface of claim 6, further comprising a headgear coupled to the faceplate. 11. The patient interface of claim 6, wherein the seal member is a unitary structure such that the oral cushion portion, the nasal interface portion, and the web of material are defined from a common material and are integral with one another.
