TL;DR: An apparatus for supporting a human or animal body, while selectively cooling weightbearing areas of the body in order to prevent or reduce damage from ischemia includes a cooling layer that is partitioned into a plurality of zones, and a surface disposed over the cooling layer to support the body as mentioned in this paper.
Abstract: An apparatus for supporting a human or animal body, while selectively cooling weight-bearing areas of the body in order to prevent or reduce damage from ischemia includes a cooling layer that is partitioned into a plurality of zones, and a surface disposed over the cooling layer to support the body. Each zone of the cooling layer is disposed for cooling a respective portion of the surface. Means are provided to selectively operate one or more zones of the plurality of the zones to cool a portion of the surface that receives pressure from a weight-bearing surface of the body being supported.

TL;DR: This study examined the use of cutaneous reactive hyperemia as a means for noninvasive assessment of wound severity of newly formed temperature‐modulated pressure injuries in a porcine model and found infrared imaging provided the better means to assess wound depth.
Abstract: This study examined the use of cutaneous reactive hyperemia as a means for noninvasive assessment of wound severity of newly formed temperature-modulated pressure injuries in a porcine model. Two methods to quantify the extent of the reactive hyperemic reflex were developed. First, color image analysis was used to measure the hue of injured tissue. The specific hue of the skin surface of the wounded site was found to provide an indication of the severity of the wounds. Second, infrared imaging, coupled with computer image processing, was used to detect differences in skin temperature. The relative surface temperature of the wounds showed a strong correlation with the presence or absence of deep tissue injury. Both techniques correlated with the severity of the injuries as determined by a histologic assessment of biopsied tissue, but infrared imaging provided the better means to assess wound depth.
