Abstract

The early detection of inadequate splanchnic tissue oxygenation would reduce the risk of hypoperfusion, severe ischaemia, and multiple organ failure [1]. None of the currently available methods provide continuous monitoring of splanchnic perfusion pre-operatively, operatively and post-operatively. In an attempt to overcome these limitations, a new fibre-optic probe utilizing the principle of reflectance pulse oximetry was developed. The separation distance between the source and detector fibres of the probe has a direct impact on the quality of the photoplethysmographic (PPG) signal and the accurate estimation of blood oxygen saturation (SpO2) [2]. Prior to finalising the probe design, an investigation was conducted to establish the optimum source-detector separation.
