Background: The speculation that cerebral tissue oxygen saturation (SctO2) measured using tissue near-infrared spectroscopy reflects the balance between cerebral metabolic rate of oxygen and cerebral oxygen delivery has not been validated.

Cerebral blood flow and tissue oxygen saturation in immediate and progressive ischemia in rat brain
Neurological Research, 2001The aim of the present study was to investigate whether immediate ischemia is more harmful to the brain than progressive ischemia. To do so, we examined the correlation between the degree and the process of ischemia using hypobaric hypotension technique, which was used to reduce systemic blood pressure acutely or progressively below the lower threshold

Objective Preterm infants often need red blood cell (RBC) transfusions. The aim of this study was to determine whether haemoglobin levels before transfusion were associated with regional cerebral tissue oxygen saturation (rcSO2) and fractional tissue oxygen extraction (FTOE) and whether RBC transfusions were ...

Near-infrared monitoring of cerebral tissue oxygen saturation and blood volume in newborn piglets
American Journal of Physiology-Heart and Circulatory Physiology, 1997Near-infrared spectrophotometry (NIRS) potentially provides a tool for noninvasive tissue oxygenation and blood volume monitoring. Cerebral monitoring could be useful in the prevention of hypoxic ischemic brain injury in newborns. This study sought to validate such NIRS measurements in normoventilated, hypocapnic, and hypoxemic states in the brain of ...

The balance between cerebral tissue oxygen consumption and supply can be continuously assessed by cerebral tissue oxygen saturation (SctO2) monitor. A construct consisting of three sequential questions, targeting the physiology monitored, the intervention implemented, and the outcomes affected, is proposed to critically appraise this monitor.

Cerebral oximetry is normally placed on the upper forehead to monitor the frontal lobe cerebral tissue oxygen saturation (SctO2). We present a case in which the SctO2 was simultaneously monitored at both frontal and parietal regions during internal carotid artery (ICA) stenting.

✓ Monitoring of cerebral oxygenation is considered to be of great importance in minimizing secondary hypoxic and ischemic brain damage following severe head injury. Although the threshold for cerebral hypoxia in jugular bulb oximetry (measurement of O2 saturation in the jugular vein (SjvO2)) is generally accepted to be 50% oxygen saturation, a ...
