• Description:
  Pulmonary waveform generators consisting of motor driven piston pumps are commonly used to test respiratory function equipment. Gas compression within these generators can produce significant distortion of the output flow-time profile when testing peak expiratory flow (PEF) meters. The waveform generator with load (PEF meter connected at the generator output) was modeled as a time varying RC circuit, where resistance represents flow resistance of the pump load, and capacitance represents gas compliance in the pump chamber. Resistance and capacitance are time-varying parameters since R is a nonlinear function of flow, and C varies as a function of pump volume. [Description provided by NIOSH]
