Abstract

See full text

Disclosed is a system and method for regulating tourniquet cuff pressure to restrict blood flow penetration past the cuff based on a personalized restrictive pressure (PRP). The system includes mechanisms for estimating a limb occlusion pressure (LOP) by determining a minimum pressure at which arterial blood penetration past an applied tourniquet cuff is stopped and measuring a pulsation characteristic associated with the LOP. Thereafter, the system establishes a PRP by determining a second pressure that restricts but does not stop arterial blood penetration past the cuff and that corresponds to a second pulsation characteristic differing by a percentage from the pulsation characteristic associated with the LOP. During a limb-activity time period, the system maintains pressure in the applied tourniquet cuff near the PRP, thereby restricting but not stopping arterial blood penetration past the cuff during the activity time period.
