Wound Bed Preparation (WBP) can be described as the management effectiveness of other therapeutic measures. The 4 basic aspects of WBP can now be represented by an acronym, TIME. T= tissue (non-viable or deficient).  I= infection or inflammation.  M= moisture control. E= epidermal margin.  Focusing on the “M” in TIME, collagen dressings possess properties which lend themselves to exudate management.  Typically exudate is caused by the breakdown of necrotic tissue (via enzymatic, autolytic or biological debridement), an inflammatory response contributed to microbial contamination/infection or edema due to venous disease. The purpose of this study is to investigate various physical properties of several collagen based dressings, comparing and contrasting efficacy with respect to exudate management.  Absorption Rate, Total Absorption, Absorption under Compression, Demand Absorbency and Wear Time were determined via ASTM (standard test methodologies).  From the data it is apparent that there are distinct differences amongst the collagen based dressings evaluated in this study in all parameters measured. The rate of Absorption test showed that dressing A had a faster rate of absorption than the dressing B. These results correlate with the demand absorbency results which showed that dressing A demanded fluid at a faster rate than dressing B.  The total of the wound to accelerate endogenous healing or to facilitate the absorption capacity and absorption under compression tests showed that the dressing A products had mean results of approximately 20 g/100cm².  These results were much higher than the results for dressing B.
