Abstract
A method and apparatus for occlusion monitoring in a flow circuit using pressure waveform analysis. The flow circuit includes a first conduit and a second conduit which fluidly interconnects a fluid supply with the first conduit. A pump is disposed in an intermediate portion of the second conduit. Monitoring of the pressure in the first conduit is used to identify any occlusions in that portion of the second conduit which is disposed between the pump and the fluid supply.
