Claim Text:
1. A method for determining operating conditions of a surgical pump system connected to a high resistance inflow cannula relative to a surgical site in a joint of a patient body for receiving the inflow cannula and an endoscope comprising: providing a pump system having a pump control processor and an inflow drive mechanism including an inflow pump motor for outputting fluid through the inflow cannula to the surgical site disposed in the joint; providing an inflow pump cassette for mounting to the inflow drive mechanism; providing a pump housing configured to include the inflow drive mechanism and to receive the inflow pump cassette in driving relation with the inflow drive mechanism; initially driving the inflow pump motor at a cannula in-joint test RPM value; measuring P determining that measured P reducing the RPM value that is output by the inflow pump motor to a flow test RPM value after the determination that P determining that measured P wherein the pump control processor is configured to obtain the cannula in-joint test RPM value, the flow test RPM value, the P
