A respiratory therapy device including a housing and an interrupter valve assembly. The housing includes a patient inlet, an exhaust outlet, a chambe r, and a supply inlet. The interrupter valve assembly is associated with the housing and includes a control port fluidly connecting the patient inlet an d the first chamber, and a valve body adapted to selectively obstruct fluid flow through the control port. In a passive mode, positive fluid flow to the supply inlet does not occur, and the interrupter valve assembly interacts w ith exhaled air create an oscillatory PEP effect. In an active mode, fluid f low to the supply inlet occurs and the interrupter valve assembly operates t o create a CHFO effect. The respiratory device can serve as a passive oscill atory PEP device, and when connected to a positive pressure source, as an ac tive device. |
