Emergency nurse : the journal of the RCN Accident and Emergency Nursing Association
Considerable research has focused on pulse oximeters since their introduction into clinical practice and much of it has been limited to a study of patient hypothermia and movement. The main problems have been vaso- constriction and poor functioning of the light emission diodes in cold environments, as well as operational difficulties.

Reproducibility of Muscle Oxygen Saturation
International Journal of Sports Medicine, 2011The present study evaluated the reproducibility of tissue oxygenation in relation to oxygen consumption (VO2) across cycle exercise intensities in a test-retest design. 12 subjects (25.7±2.1 years; 24.7±1.9 kg · m(-2)) twice performed an incremental bicycle exercise protocol, while tissue oxygen saturation (StO2) in the vastus lateralis muscle was ...

Oxygen saturation and cognitive performance
Psychopharmacology, 2002The purpose of the experiments was to investigate how inhalation of 100% oxygen affected cognitive performance. A test battery was developed that was designed to capture different aspects of cognitive processes, i.e., perception, attention, working memory, long-term memory and prospective memory.

The Assessment of Nocturnal Oxygen Saturation
Clinical Science, 19831. Existing methods of assessing nocturnal episodic hypoxaemia are either insensitive or ignore the majority of the available data. 2. We describe a method of analysis using offline digital processing. A distribution of oxygen saturation (Sao2) with time is produced from all the available data, and subjected to moment analysis to produce

Nomenclature of Oxygen Saturation
1994This paper addresses a controversial question relating to the definition of oxygen saturation as O2 content/O2 capacity: Whether, O2 capacity should include a) only oxyhemoglobin and deoxyhemoglobin, designated herein as O2Hb + HHb, or b) total hemoglobin, tHb = O2Hb + HHb + COHb + MetHb.

[The physiopathology of oxygen venous saturation].
Minerva anestesiologica, 1992The paper underlines the importance of continuous SvO2 monitoring by means of the insertion of a modified Swan-Ganz optic fibre catheter into the pulmonary artery. Following an analysis of the factors which regulate O2 transport and ATP formation, together with metabolism self-regulating mechanisms which intervene in periods of stress to guarantee ...

Oxygen Saturation in Children in the Postoperative Period
Anesthesia & Analgesia, 1992Some adult patients have periods of significant oxygen desaturation after surgery but, other than for immediately after surgery in the recovery room, few data are available in children. We monitored overnight paired preoperative and postoperative oxygen saturations in 19 children, and overnight postoperative saturations in 50 additional children to ...

The fraction of incident light which is returned from a turbid sample contains information about the pigments within the sample. Analysis of the spectra of this returned light allows detailed information of the relative quantity of these pigments to be determined.

Oxygen Saturation and Retinopathy of Prematurity
Clinics in Perinatology, 2019Retinopathy of prematurity (ROP) is a serious disease affecting premature infants. Rates of ROP increase with decreasing gestational age. Duration of oxygen exposure is correlated with ROP. Many studies evaluating oxygen have been performed to assess impact on ROP. This article describes recent findings for oxygen saturation target studies and suggests

Oxygen delivery and venous oxygen saturation monitoring
Hospital Medicine, 2003Maintenance of adequate oxygen delivery is essential to ensure survival from shock, critical illness and major surgery. Impaired oxygen delivery can result in tissue hypoxia, anaerobic metabolism, lactic acid production and oxygen debt. If sustained, this sequence of events can lead to multiorgan failure and death.
