Absolute quantification of cerebral tissue oxygen saturation with multidistance broadband NIRS in newborn brain. [PDF]

Biomed Opt Express, 2021
Tissue oximetry with near-infrared spectroscopy (NIRS) is a technique for the measurement of absolute tissue oxygen saturation (StO 2 ). Offering a real-time and non-invasive assessment of brain oxygenation and haemodynamics, StO 2 has potential to be ...

Effects of therapeutic hypothermia on cerebral tissue oxygen saturation in a swine model of post-cardiac arrest. [PDF]

Exp Ther Med, 2020
Since the introduction of therapeutic hypothermia (TH), trends have changed in the monitoring indicators used during and after cardiac arrest. During hypothermia, the cerebral metabolic rate of oxygen is reduced, which leads to uncertainty in regional cerebral tissue oxygen saturation (SctO2).

Cerebral Tissue Oxygen Saturation Correlates with Emergence from Propofol-Remifentanil Anesthesia: An Observational Cohort Study. [PDF]

J Clin Med, 2022
Anesthesia emergence is accompanied by changes in cerebral circulation. It is unknown whether cerebral tissue oxygen saturation (SctO2) could be an indicator of emergence. Changes in SctO2, bispectral index (BIS), mean arterial pressure (MAP), and heart rate (HR) were evaluated during the emergence from propofol-remifentanil anesthesia.

Differences Between Central Venous and Cerebral Tissue Oxygen Saturation in Anaesthetised Patients With Diabetes Mellitus. [PDF]

Sci Rep, 2019
AbstractThe brain has high oxygen extraction, thus the regional cerebral tissue oxygen saturation (rSO2) is lower than the central venous oxygen saturation (ScvO2). We hypothesised that diabetes widens the physiological saturation gap between ScvO2 and rSO2 (gSO2), and the width of this gap may vary during various phases of cardiac surgery.

Feasibility of absolute cerebral tissue oxygen saturation during cardiopulmonary resuscitation. [PDF]

Crit Care, 2013
Abstract Introduction Current monitoring during cardiopulmonary resuscitation (CPR) is limited to clinical observation of consciousness, breathing pattern and presence of a pulse. At the same time, the adequacy of cerebral oxygenation during CPR is critical for neurological outcome and thus survival ...

Cerebral Tissue Oxygenation and Regional Oxygen Saturation Can Be Used to Study Cerebral Autoregulation in Prematurely Born Infants [PDF]

Pediatric Research, 2011
The coupling of cerebral intravascular oxygenation (dHbD) with mean arterial blood pressure (MABP) was taken as a reflection of autoregulation assuming constant arterial oxygen content. However, this method is sensitive to movement artifacts. We examined whether the cerebral tissue oxygenation index (cTOI) and regional oxygen saturation (rScO2) may ...

Differences Between Hepatic and Cerebral Regional Tissue Oxygen Saturation at the Onset of Intradialytic Hypotension

Journal of Clinical Medicine, 2023
Background: Intradialytic hypotension (IDH) is a critical pathological condition associated with all−cause mortality in patients undergoing hemodialysis (HD). However, few studies have investigated IDH-related changes in hepatic and cerebral regional tissue oxygen saturation (rSO2).

Cerebral Tissue Regional Oxygen Saturation as a Valuable Monitoring Parameter in Pediatric Patients Undergoing Extracorporeal Membrane Oxygenation [PDF]

Frontiers in Pediatrics, 2021
Objective: Brain function monitoring technology for extracorporeal membrane oxygenation (ECMO) support has been developing quite slowly. Our objective was to explore the data distribution, variation trend, and variability of cerebral tissue regional oxygen saturation (CrSO2) in pediatric patients undergoing ECMO.Methods: Eight patients who received ...

Near-infrared spectroscopy: An important tool during the blalock-taussig shunt

Annals of Cardiac Anaesthesia, 2020
Near infra red spectroscopy (NIRS) is a noninvasive diagnostic tool for measuring regional oxygen saturation (rSO2). Cerebral oxygenation measured with NIRS is used to corroborate mixed venous oxygenation and hence considered an indicator of tissue ...
