Early detection and rapid treatment of tissue hypoxia are important goals. Venous oxygen saturation is an indirect index of global oxygen supply-to-demand ratio. Central venous oxygen saturation (ScvO2) measurement has become a surrogate for mixed venous oxygen saturation (SvO2). ScvO2 is measured by a catheter placed in the superior vena cava.

Femoral venous oxygen saturation is no surrogate for central venous oxygen saturation*
Critical Care Medicine, 2012The purpose of our study was to determine if central venous oxygen saturation and femoral venous oxygen saturation can be used interchangeably during surgery and in critically ill patients.Prospective observational controlled study.Nonacademic university-affiliated teaching hospital in The Netherlands.One hundred cardiac outpatients, 30 high-risk ...

The Assessment of Nocturnal Oxygen Saturation [PDF]
Clinical Science, 1983 1. 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

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.

Misconceptions in Reporting Oxygen Saturation
Anesthesia & Analgesia, 2007We describe some misconceptions that have become common practice in reporting blood gas and cooximetry results. In 1980, oxygen saturation was incorrectly redefined in a report of a new instrument for analysis of hemoglobin (Hb) derivatives. Oxygen saturation (sO2) was redefined as the ratio of oxyhemoglobin (O2Hb) to total Hb instead of the ratio of ...

This chapter describes how desaturation during a cardiopulmonary exercise test (CPET) is uncommon. A fall of more than 4% from resting values is considered abnormal. Oxygen desaturation is usually caused by lung or pulmonary vascular disease, reflecting ventilation–perfusion inequality or impaired diffusion.
