Limb Occlusion Pressure (L.O.P.) 

Technology that’s designed to calculate a patient pressure at an individual level and apply the minimum amount of tourniquet pressure needed to occlude a limb at a specific time for a specific patient. Studies have shown LOP effective at reducing tourniquet pressure versus a static setting of 300-350. Lower pressure helps reduce complications associated with tourniquet use.1

Line Occlusion Detection (Acoustic Reflectometry)

Technology that is intended to help identify a line occlusion between the machine and cuff. The technology decreases the unintentional risk of leaving pressure in a tourniquet cuff.

Cuff Alert

Technology intended to prevent setting the unit to STANDBY with pressure in the tourniquet cuff.

Automatic IVRA Cuff Lock Out

Technology that is intended to prevent accidental dual cuff release. Without additional steps or notification, the machine will prompt users to confirm the intent to deflate a second cuff. Improper deflations have resulted in serious injuries and death.

Advanced Leak Detection

Technology that monitors a cuff for minor variations intraoperatively with the intention of reporting potential cuff/hose leaks.

Pre-Op Cuff Test

Technology that allows for bedside testing of cuff pre-operatively to ensure proper function.

Personalized Pressure™ Technology

Personalized Pressure can help surgeons choose a more individual, often lower, cuff pressure. Lower tourniquet cuff pressure reduces post-operative wound complications after TKA.1

Applying lower tourniquet pressure has been found to result in less post-operative pain. One study demonstrated that an average thigh tourniquet pressure of 230mmHG resulted in statistically significant lower pain over a multi-day recovery period versus a tourniquet pressure of 350mmHG.2

Minimizing tourniquet pressure and pressure gradients by using Personalized Pressure helps minimize the risk of nerve-related injuries.3
