1. A system for use with a surgical instrument, the system comprising:
- an end effector comprising a first and second electrode;
a memory circuit to store computer-executable instructions for performing a biological material accumulation monitoring process; and
a processor coupled to the memory circuit, the processor configured to execute the computer-executable instructions, wherein executing the computer-executable instructions causes the processor to;
initiate a first treatment cycle;
measure a first plurality of impedance values during the first treatment cycle;
determine a first minimum impedance value for the first treatment cycle based on the measured first plurality of impedance values;
compare the first minimum impedance value to a predetermined impedance threshold; and
generate an alert in the event that the first minimum impedance value exceeds the predetermined impedance threshold.
