Cerebral tissue oxygen saturation during therapeutic hypothermia in post-cardiac arrest patients

Resuscitation, 2013
This observational study was performed to assess the cerebral tissue oxygen saturation during and after therapeutic hypothermia in comatose patients after out-of-hospital cardiac arrest.We performed a prospective observational study on the cerebral tissue oxygen saturation (SctO(2)) in post-cardiac arrest patients treated with therapeutic hypothermia ...

Association Analysis of the Cerebral Fractional Tissue Oxygen Extraction (cFTOE) and the Cerebral Oxygen Saturation (crSaO2) with Perinatal Factors in Preterm Neonates: A Single Centre Study

Journal of Clinical Medicine, 2022
(1) Background: Near-infrared spectroscopy (NIRS) is a non-invasive, easily performed method of monitoring brain oxygenation. The regional cerebral oxygen saturation (crSaO2) and the cerebral fractional tissue oxygen extraction (cFTOE) evaluated by NIRS provide more accurate information on brain oxygenation than the blood oxygen saturation.

Feasibility of long-term cerebral and peripheral regional tissue oxygen saturation measurements

Physiological Measurement, 2014
The aim of this study was to analyse the feasibility of long-term measurements of cerebral (crSO2) and peripheral (prSO2) regional tissue oxygen saturation on the first day of life by determining the amount of artefacts and their influence on rSO2. Near infrared spectroscopy (NIRS) measurements were performed fronto-parietal left (crSO2) and on the ...

Cerebral, Renal, and Splanchnic Tissue Oxygen Saturation Values in Healthy Term Newborns

American Journal of Perinatology, 2013
To determine cerebral regional tissue oxygen saturation (CrSO2), renal regional tissue oxygen saturation (RrSO2), and splanchnic regional tissue oxygen saturation (SrSO2) values in healthy term infants.Near-infrared spectroscopy was used to simultaneously measure CrSO2, RrSO2, and SrSO2 continuously for a 1-hour period on the first and second days of ...

Changes of Cerebral Tissue Oxygen Saturation at Sleep Transitions in Adolescents

2014
In adults, cerebral oxy-([O₂Hb]) and deoxyhemoglobin concentrations ([HHb]) change characteristically at transitions of sleep stages. The aims were to assess these changes in adolescents and additionally to measure tissue oxygen saturation (StO₂) by near infrared spectroscopy (NIRS).

Arterial Oxygen Saturation, Pulse Oximetry, and Cerebral and Tissue Oximetry in Hypobaric Hypoxia

Aerospace Medicine and Human Performance, 2018
INTRODUCTION: Clinical accuracy of pulse oximeters (giving Spo2) is routinely tested down to an Sao2 of 70%, but lower oxygen saturations are often experienced during hypobaric hypoxia. Cerebral (Sco2) and peripheral tissue (Sto2) oxygen saturations can be measured using near infra-red spectroscopy. In a project simulating oxygen system failure during

Cerebral Tissue Oxygen Saturation During Percutaneous Cardiopulmonary Support in a Canine Model of Respiratory Failure

Artificial Organs, 2000
Abstract: Percutaneous cardiopulmonary support (PCPS) has come to be applied for cardiopulmonary resuscitation and in the management of severe respiratory failure as well as severe heart failure. We investigated cerebral tissue oxygen saturation during PCPS in a canine model of respiratory failure using near‐infrared spectroscopy.
