Evaluating the combined effects of gravity and compression on the fluid handling properties of surgical dressings.

A new test method is described which provides a convenient technique for assessing the combined effects of gravity and compression on the fluid handling characteristics of surgical dressing which can have important implications for their use in the treatment of venous ulcers. Simple ways of improving use of the fluid handling capacity of products currently used clinically are suggested, and the possibility of developing a dressing specifically designed to resist gravitational effects is discussed.
