Significant Pressure Loss Occurs Under Tourniquets Within Minutes of Application.

Background: Pressure decreases occur after tourniquet application, risking arterial occlusion loss. Our hypothesis was that the decreases could be mathematically described, allowing creation of evidence-based, tourniquet-reassessment- time recommendations.

Methods: Four tourniquets with width (3.

Tourniquet pressures: strap width and tensioning system widths.

Background: Pressure distribution over tourniquet width is a determinant of pressure needed for arterial occlusion. Different width tensioning systems could result in arterial occlusion pressure differences among nonelastic strap designs of equal width.

Methods: Ratcheting Medical Tourniquets (RMTs; m2 inc.
