Abstract:
1. An apparatus comprising: a blower having an intake and an exhaust; a direction valve having an intake port operationally connected to said blower intake, an exhaust port operationally connected to said blower exhaust, an atmosphere port, and a common port; an oscillator having a connector port and a valve port operationally connected to said valve common port, said oscillator including a chamber between said connector port and said valve port and a rotatable disc within said chamber; a patient interface coupled to the connector port and in communication with a patient's respiratory tract; a controller controlling operation of said apparatus; said apparatus having an insufflation mode wherein said controller sets said direction valve such that said exhaust port is operationally connected to said common port and said intake port is operationally connected to said atmosphere port, thereby providing positive pressure at said patient interface for an insufflation; said apparatus having an exsufflation mode wherein said controller sets said direction valve such that said intake port is operationally connected to said common port and said exhaust port is operationally connected to said atmosphere port, thereby providing negative pressure at said patient interface for an exsufflation; and said apparatus having a flutter mode wherein said controller rotates said rotatable disc at a settable frequency during exsufflation.
