creator Williams, David R. creator Wilson, Nicole April creator Meade, Kevin Philip creator Mansy, Hansen A. A spirometer for measuring fluid flow, particularly associated with exhalation of respiratory patients. The spirometer of this invention preferably has a fluidic oscillator wherein the fluid oscillates within a chamber of the fluidic oscillator. An oscillation frequency of the fluid flow within the chamber is correlated to a flow rate. A computer is used to process input data, such as data representing frequency of the oscillatory flow within the chamber, to a flow rate passing through the spirometer. The spirometer of this invention may have no moving parts, which results in the need for only a design calibration and no periodic calibrations throughout use of the spirometer.
