Pressure to Heal

Welcome to All Sensors “Put the Pressure on Us” blog. This blog brings out pressure sensor aspects in a variety of applications inspired by headlines, consumer and industry requirements, market research, government activities, and you.

Pressure to Heal

Applying pressure to a wound is the first step toward the healing process. This could be something as simple and commonplace as getting a vaccination or having blood taken where the pressure is simply applied by a finger. For a more life-threatening wound, a tourniquet might be required. But how much pressure should be applied?

Sufficient pressure needs to be applied to stop the flow of blood so clotting (occlusion) can occur. If blood flow cannot be stopped at the site, direct pressure to an artery may be required. For medical professionals, the term limb occlusion pressure (LOP) is used. This is “the minimum pressure required, at a specific time by 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.”

For hospitals an Automatic Tourniquet System provides a means of monitoring and controlling the applied pressure. In an operation, equipment such as the Zimmer A.T.S. 3000 uses LOP technology to sense, calculate and report the cuff pressure necessary for complete blood occlusion in the operative limb. Applied to the index finger or second toe of the patient’s operative limb prior to the surgical procedure, the LOP sensor in the A.T.S. 3000 provides a recommended tourniquet pressure (RTP) setting in approximately 30 seconds.
