A respiratory treatment device includes a housing enclosing a chamber, a chamber inlet configured to receive a flow of air into the chamber, a first chamber outlet configured to permit the flow of air to exit the chamber, and a second chamber outlet configured to permit the flow of air to exit the chamber. A vane mounted within the chamber is configured to rotate between a first position where the flow of air is directed to exit the chamber through the first chamber outlet, and a second position where the flow of air is directed to exit the chamber through the second chamber outlet. A blocking member disposed on the vane is moveable relative to the chamber inlet between a closed position where the flow of air through the chamber inlet is restricted, and an open position where the flow of air through the chamber inlet is less restricted.

1. A respiratory treatment device comprising: a housing enclosing a chamber;a chamber inlet configured to receive a flow of air into the chamber through the chamber inlet;a first chamber outlet configured to permit the flow of air to exit the chamber through the first chamber outlet;a second chamber outlet configured to permit the flow of air to exit the chamber through the second chamber outlet;a vane mounted within the chamber, the vane being configured to rotate in response to the flow of air through the chamber during a single period of exhalation repeatedly between a first position where the flow of air is directed to exit the chamber through the first chamber outlet, and a second position where the flow of air is directed to exit the chamber through the second chamber outlet;a blocking member disposed on the vane, the blocking member moveable relative to the chamber inlet during the single period of exhalation repeatedly between a closed position where the flow of air through the chamber inlet is restricted, and an open position where the flow of air through the chamber inlet is less restricted. 2. The respiratory treatment device of claim 1, wherein the vane is prohibited from completing a complete revolution. 3. The respiratory treatment device of claim 1, wherein a size of the blocking member is greater than a size of the chamber inlet. 4. The respiratory treatment device of claim 1, wherein a size of the blocking member is less than a size of the chamber inlet. 5. The respiratory treatment device of claim 1, wherein an axis of rotation of the vane is offset from a center of the vane. 6. The respiratory treatment device of claim 1, furthering comprising a mouthpiece, wherein a cross sectional area of the mouthpiece is larger than a cross sectional area of the chamber inlet. 7. The respiratory treatment device of claim 6, further comprising an inhalation port in communication with the mouthpiece, the inhalation port comprising a one-way valve configured to open upon inhalation and close upon exhalation. 8. The respiratory treatment device of claim 1, wherein a cross-sectional area of the chamber inlet is less than at least one of a cross-sectional area of the first chamber outlet or a cross-sectional area of the second chamber outlet. 9. A respiratory treatment device comprising: a housing enclosing a chamber;an inlet configured to receive a flow of air into the chamber;an outlet configured to permit the flow of air to exit the chamber;a blocking member moveable relative to the outlet during a single period of exhalation repeatedly between a closed position where the flow of air through the outlet is restricted, and an open position where the flow of air through the outlet is less restricted;at least one vane rotatably mounted in the housing, the at least one vane being configured to move the blocking member during the single period of exhalation repeatedly between the closed position and the open position in response to the flow of air; wherein the at least one vane comprises a turbine having a plurality of vanes; and wherein the blocking member is prohibited from completing a full revolution. 10. The respiratory treatment device of claim 9, wherein the blocking member is connected to the at least one vane by a shaft and at least one linkage. 11. The respiratory treatment device of claim 10, wherein the shaft and the at least one linkage cooperate to move the blocking member in linear reciprocating motion. 12. The respiratory treatment device of claim 9, wherein the blocking member is configured to reciprocate between the open position and the closed position in response to movement of an arm connected to the at least one vane. 13. The respiratory treatment device of claim 9, wherein the blocking member is biased toward the open position. 14. The respiratory treatment device of claim 9, wherein the chamber comprises a first portion enclosing the at least one vane and a second portion enclosing the blocking member. 15. The respiratory treatment device of claim 14, wherein the first portion is in communication with the second portion. 16. The respiratory treatment device of claim 9, further comprising a mouthpiece, wherein a cross sectional area of the mouthpiece is larger than a cross sectional area of the inlet. 17. The respiratory treatment device of claim 16, further comprising an inhalation port in communication with the mouthpiece, the inhalation port comprising a one-way valve configured to open upon inhalation and close upon exhalation. 18. The respiratory treatment device of claim 9, wherein a cross-sectional area of the chamber inlet is less than a cross-sectional area of the chamber outlet. 19. A method of performing respiratory treatment, the method comprising: passing a flow of air through a device having an inlet configured to receive a flow of air into a chamber through the inlet, a first outlet configured to permit the flow air to exit the chamber through the first outlet, and a second outlet configured to permit the flow of air to exit the chamber through the second outlet;rotating a vane mounted within the device in response to the flow of air through the device during a single period of exhalation repeatedly between a first position where the flow of air is directed to exit the chamber through the first outlet, and a second position where the flow of air is directed to exit the chamber through the second outlet; and, moving a blocking member disposed on the vane relative to the chamber inlet during the single period of exhalation repeatedly between a closed position where the flow of air through the chamber inlet is restricted, and an open position where the flow of air through the chamber inlet is less restricted.
