Technical Examples

A high frequency pressure oscillation device that selective restricts the flow of breathing gas to or from a patient to produce pressure spikes in the patient's airway that facilitate clearing secretions from the patient's airway. The device includes a patient circuit that defines a closed path between a source of breathing gas and the patient's airway. A valve is disposed in the patient circuit such that in an open position the path between the source of breathing gas and the airway of the patient is substantially unobstructed. When the valve is in a closed position, the path between the source of breathing gas and the patient's airway is at least partially obstructed to create the pressure spikes. An actuating system associated with the valve alternatively places the valve in the open position and in the closed position at a predetermined oscillation rate that is independent of patient effort.
