Abstract: Disclosed is a method of detecting and/or monitoring ischemia in a tissue or organ, such as a free flap transfer. The method includes the steps of measuring in real time or near-real time interstitial glucose concentration, or rate of change of interstitial glucose concentration over time, or both, in the tissue or organ. A reduced glucose concentration or a negative rate of change of glucose concentration in the tissue or organ as compared to a control glucose concentration or rate of change indicates ischemia in the tissue or organ.

Abstract: A display panel for a CB transceiver is disclosed which identifies to others the channel being used by the operator and other information such as the operator's code name or that the operator needs emergency assistance. The display panel is adapted to be installed in a motor vehicle on the front dashboard, on the rear window area, or the side windows. In the preferred embodiment, the display panel includes an electronic digital channel indicator connected to the channel selector of the CB transceiver. The numbers displayed on the channel indicator change with the channel selected on the CB transceiver. A translucent overlay is mounted within the display panel in front of the digital channel indicator, and the overlay is personalized with information about the operator. A light behind the overlay makes the information visible to others. Two flashing lights are also mounted within the display panel.
