Excerpt
Studies have suggested that tissue oxygenation saturation (StO2) values are insensitive in assessing peripheral perfusion. StO2 measurements may be more correctly interpreted if measured in association with the forearm-to-fingertip skin-temperature gradient (Tskin-diff). A Tskin-diff threshold of 0°C has been showed to reflect vasoconstriction. We aimed to propose a different approach for the interpretation of StO2 by adding Tskin-diff monitoring and to characterize the pattern of StO2 dynamics in patients with peripheral vasoconstriction and vasodilation. We hypothesize that monitoring StO2 with Tskin-diff can more adequately predict ICU complications than StO2 itself. …
