• and
• j. using said portable electric pump system to reduce pressure in said BFRT cuff within 10 seconds after said step of termination air flow;
• said portable electric pump system configured to A) reduce pressure in said BFRT cuff until said selected percent of limb occlusion pressure (LOP) or said selected preset percent of limb occlusion pressure (LOP) in said BFRT cuff is obtained after said portable electric pump system determined that an LOP was obtained in said BFRT cuff, and B) stop operation of said portable electric pump once said selected percent of limb occlusion pressure (LOP) or said selected preset percent of limb occlusion pressure (LOP) in said BFRT cuff is obtained.
