Efficacy of the Dabir Surfaces Micropressure Overlay for Decubitus Ulcer Prevention During Cardiac Surgery

"The study intervention is the use of the Dabir micropressure overlay on the operating room table during surgical operations. The device is positioned on top of a standard foam pad and gel heat exchanger. The overlay is already in use in some (but not all) adult cardiac operating rooms.~The overlay will be present on the operating room table for all adult cardiac operations. On odd calendar dates the device will be powered on, and on even calendar dates the device will be powered off."
