Quantifying Support Surface Moisture Removal

Low-air-loss mattress systems are used for the treatment and prevention of pressure ulcers(1). As an improved description, these mattresses are now being called support surfaces for microclimate management. A few test methods have been proposed to quantify the microclimate management performance of these mattresses(2-4). Recent research has resulted in a new test method that offers the potential of repeatable results that are easily understood by practitioners.  The test methodology was developed in conjunction with the National Pressure Ulcer Advisory Panel Support Surface Standards Initiative. This test method differentiates the moisture removal capability of various support surfaces. The test method is relatively inexpensive to perform and does not require a high level of technical skill. The steady-state transmission of moisture from the simulated patient surface to below the mattress cover can be determined. The results allow a practitioner to select which support surface removes the amount of moisture he/she prefers for their clinical setting.
