Clinical Applications of Tissue Oxygen Saturation Measurements

2011
This paper describes a number of clinical applications of non-invasive tissue haemoglobin oxygen saturation (StO2) measurements using both visible and near infrared spectrophotometric techniques. In two cases they became routine clinical tools. The applications of visible spectrophotometry described include amputation level viability prediction in ...

Tissue oxygen saturation measured by near infrared spectrophotometry correlates with arterial oxygen saturation during induced oxygenation changes in neonates

Physiological Measurement, 2000
The aim of this study was to compare quantitatively the changes in tissue oxygen saturation (TOS), determined by two algorithms (TOSc and TOSa) based on near-infrared spectrophotometry, to the changes in arterial oxygen saturation (SaO2) measured by pulse oximetry.

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).

Numerical Optimisation of a NIRS Device for Monitoring Tissue Oxygen Saturation

2022
The present work aims to develop a wearable, textile-integrated NIRS-based tissue oxygen saturation (StO2) monitor for alerting mobility-restricted individuals - such as paraplegics - of critical tissue oxygen de-saturation in the regions such as the sacrum and the ischial tuberosity; these regions are proven to be extremely susceptible to the ...

Noninvasive Tissue Oxygen Saturation Measurements Identify Supply Dependency

Journal of Surgical Research, 2010
Hemorrhagic shock can lead to multiple organ failure and death. We have previously shown that noninvasive measurement of tissue oxygen saturation (StO(2)) has predictive value for outcomes in patients suffering hemorrhagic shock. Our study objectives were twofold: (1) to compare invasive and noninvasive measurements of local and systemic tissue ...

Compression Sleeves Increase Tissue Oxygen Saturation But Not Running Performance

International Journal of Sports Medicine, 2011
The purpose of this study was to determine the effects of calf compression sleeves on running performance and on calf tissue oxygen saturation (StO2) at rest before exercise and during recovery period. 14 moderately trained athletes completed 2 identical sessions of treadmill running with and without calf compression sleeves in randomized order.

Raising airway resistance in laryngctomees incrases tissue oxygen saturation

Clinical Otolaryngology, 1996
The physiological airflow resistance from the anterior nares to the upper trachea has recently been documented. This resistance is thought to be important in preventing alveolar collapse and in maintaining the optimum lung ventilation: perfusion ratio.

Prognostic implications of tissue oxygen saturation in human septic shock

Intensive Care Medicine, 2012
To analyze the prognostic value of tissue oxygen saturation (StO(2)) in septic shock patients with restored mean arterial pressure (MAP).This was a prospective observational study of patients admitted to the ICU in the early phase of septic shock, after restoration of MAP. Demographic data, severity score, hemodynamics, blood lactate, acid-base status,

Examination of sacral tissue oxygen saturation among immobile patients

Journal of Clinical Nursing, 2018
Aims and objectivesTo explore the effect of immobility on sacral tissue oxygen saturation in patients lying on a supporting surface in supine position.BackgroundGuidelines in regard to preventing pressure ulcers recommend that patients lying on a standard bed should change their positions every 2 hr and that patients on a supporting surface should ...

Correction of tissue oxygen saturations using arterial oxygen levels for cerebrovascular autoregulation analysis

2017 39th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2017
Adequate perfusion of blood is fundamental to brain tissue viability, and failure to appropriately regulate cerebral blood flow is related to neurological damage. Cerebral tissue oxygenation is commonly used as a surrogate of cerebral blood flow for non-invasive measures of autoregulation, but may only be valid during periods of constant oxygen ...
