Effects of spinal immobilization at a 20° angle on cerebral oxygen saturations measured by INVOS™

In this study, we aimed to investigate whether performing the immobilization at 20° instead of 0° changes cerebral oxygenation. 33 volunteers were put in a hard cervical collar and backboard at 0° and immobilized for 30 min. The cerebral oxygen saturations of the volunteers were measured at 1, 5, and 30 min after the start of the procedure (Group 1). The volunteers were asked to return the day after the Group 1 procedure but at the same time....
