Estimating the Number and Size of Sheets
Previous Previous | Next Next

Estimate the number of sheets of INTEGRA™ Bilayer Matrix Wound Dressing you will need available using the following guidelines.

  • Determine the size of the area to be covered
  • Determine product size (e.g., 20x25cm). If you
    are planning to mesh the INTEGRA™ Bilayer Matrix Wound Dressing, it is suggested that you use the 10x25cm (4x10 inch) size.
  • Calculate the number of sheets by dividing the Surface Area by Sheet Area (e.g., 1750cm/500cm = 3.5 sheets)
  • Due to difficulties in estimating surface area and losses due to trimming, it is often advisable to allow for an additional 10% (e.g., 3.5 sheets x 1.10 = 3.85 Sheets)
