Real-time, non-invasive detection of tissue oxygen saturation (rSO2) has been possible using near-infrared spectroscopy (NIRS). Cerebral oximetry has been extensively studied and has the potential to provide a measurable clinical benefit beyond cardiovascular and thoracic procedures.The measurement of rSO2 is organ-specific and regional, reflecting perfusion and metabolism. It is not pulsatility or flow-dependent. It may offer advantages over traditional monitors such as pulse oximetry. Thus, there is great potential to use rSO2 monitoring in the operating room, because it allows us to estimate a patient's condition and surgical effects. We describe the utility of rSO2 as a first alert of impending organ failure in patients with shock physiology and how to use it for tissue oximetry to detect surgical effects.
