Reproducibility of Muscle Oxygen Saturation

International Journal of Sports Medicine, 2011
The 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 during Electroconvulsive Therapy

British Journal of Psychiatry, 1987
Oxygen saturation was measured during anaesthesia and electroconvulsive therapy (ECT) using ear oximetry. Significant hypoxia occurred during some treatments; desaturation related to the number of ventilations performed after muscle relaxation and prior to the shock. Desaturation did not correlate significantly with seizure duration.

Nomenclature of Oxygen Saturation

1994
This 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.

Oxygen saturation and cognitive performance

Psychopharmacology, 2002
The 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.

Oxygen saturation monitoring during endoscopy

Surgical Endoscopy, 1990
The role of monitoring during endoscopy is not clearly defined. We have prospectively investigated continuous arterial oxygen saturation (SaO2) monitoring in 326 patients undergoing upper endoscopy (EGD) and 90 undergoing colonoscopy. Automated blood pressure recording was evaluated in 278 of these patients.

Misconceptions in Reporting Oxygen Saturation

Anesthesia & Analgesia, 2007
We 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 ...

Oxygen saturation monitoring.

Minerva anestesiologica, 2002
Pulse-oximeter is described as the most important technological proceeding for monitoring the patients' safety during anesthesia, after surgery and in emergency. This opinion was widely confirmed in the 1990s when pulse-oximeter has been definitively introduced in the standard for base monitoring in the OR and has been proposed for routinary use also ...

Analogue electronic oxygen-saturation calculator

Medical & Biological Engineering & Computing, 1977
An electronic analogue computer circuit for the calculation of the oxygen-saturation value of a blood sample is described. The PO2 input value is corrected to standard conditions (pH=7·4, t=37°C and BE=0) and fed to an analogue function generator, which transforms the corrected PO2 values into percentage oxygen saturation.
