Limb Occlusion Pressure (LOP) | 合法醫療器材資訊網

Limb Occlusion Pressure (LOP) is the minimum pressure required, at a specific time in a specific tourniquet cuff applied to a specific patient’s limb at a specific location, to stop the flow of arterial blood into the limb distal to the cuff. Many studies and reviews published in the clinical literature have shown that higher tourniquet pressures and higher pressure gradients[1] are associated with higher risks of tourniquet-related injuries, e.g. [1-7].  Studies have also shown that lower tourniquet pressures are associated with lower complications and pain, e.g. [8-9].  Therefore, when a tourniquet is used in surgery, the best practice is to use the lowest tourniquet pressure that is safely possible and to use a tourniquet cuff that is designed to produce the lowest pressure gradients.

LOP is personalized to each individual patient an...
