In another aspect of the disclosure, an ablation system is provided including an ablation probe defining a fluid path for circulation of fluid therethrough, a generator (115) configured to supply energy to the ablation probe for treating tissue, a pump (117) configured to pump fluid through the fluid path of the ablation probe to cool the ablation probe, a sensor (180) configured to measure an electrical current drawn by the pump, and a computing device (100) configured to determine a status of the ablation system based on the measured electrical current.1/6 0O 0L 0c LC
