The microclimate of an area while sitting on a cushion must be monitored to prevent temperature build-up which leads to moisture, maceration, and pressure ulcer.
Clinicians should consider microclimatic materials which cool the area and delay temperature build-up. Microclimatic materials will also reduce perspiration (moisture).
Although tissue breakdown has been attributed to excess heat and moisture, skin that is too dry is also more prone to pressure ulcer.
Microclimatic material encourages the passage of air, heat, and water vapor from the user; therefore materials that promote a stable microclimate in the cushion should be considered.
