  • the compression may be measured by compression measurement equipment as manufactured e.g. by Instron or Bolam Corporation.
  • the compression may be divided into categories or classes as e.g. as follows: light (10-15 mmHG), mild (15-20 mmHG), moderate (20-30 mmHG), and firm compression (30-40 mmHG).
