Compression Bandage System:The compression bandage system is comprised of up to four bandage layers that provide pressure and support to treat venous ulcerations and disorders. The first layer is made with a heavy wool bandage, which serves to wick moisture away from the skin and maintain a dry, sanitary treatment area. A cotton crepe layer is next, providing absorption and elasticity to secure the bandage system without additional compression. Next is the elastic bandage layer, which allows for even compression around the first two layers, and finally the cohesive bandage layer that provides compression and overall bandage security.ProductDescriptionSizeQtyH-3LB: Three-Layer Compression Bandage System  3 Rolls/Box;8 Boxes/CaseOrthopedic Padding4" X 3.8 YardsCrepe Bandage4" x 3  YardsLatex-Free Cohesive Bandage4" x 3.2 YardsH-4LB: Four-Layer Compression Bandage System  4 Rolls/Box;8 Boxes/CaseOrthopedic Padding4" X 3.8 YardsCrepe Bandage4" x 3 YardsHigh Compression Bandage4" x 5 YardsLatex-Free Cohesive Bandage4" x 3.2 YardsGuidelines for using of Multilayer compression bandage systems(Based on RCN and SIGN guideline and International Leg Ulcer Advisory Board recommendations)1. High compression - sub-bandage pressure 35-40mmHg: ABPI ≥0.8: Four-layer bandaging (4LB-orthopedic padding, crepe, high elastic bandage layer, cohesive bandage layer)2. Reduced compression - sub-bandage pressue 17-25mmHg:ABPI 0.7: Three-layer bandaging (orthopedic padding, crepe, cohesive bandage layer)ABP1 0.6: Three-layer bandaging (orthopedic padding, crepe, long-stretch elastic bandage layer)ABPI< 0.5: avoid compression except with medical supervision
