Pulse oximetry is a widely used, non-invasive technique for assessing arterial oxygenation by measuring oxygen saturation in peripheral blood vessels. It is a simple technique, but needs to be carried out with care to obtain reliable results. This article provides guidance on the safe use of pulse oximetry and identifies some of the advantages and ...

Correlation of Pulse Oximetry and Co-oximetry
Dimensions of Critical Care Nursing, 1997Pulse oximetry is an important advancement in noninvasive monitoring and assessment of arterial blood oxygenation. The purpose of this study was to assess the correlation of arterial oxygen saturation (SaO2) and pulse oximetry (SpO2) in critically ill patients using the ear and finger probes.

The pulse oximeter is a device for non-invasive, continuous measurement of oxygen saturation. As such it is arguably one of the most important intraoperative monitors at the disposal of anaesthetists, and efforts are being made to make pulse oximeters available at all operating locations throughout the world [Walker et al. 2009].

Continuous intra-arterial oximetry, pulse oximetry, and co-oximetry during cardiac surgery
Journal of Cardiothoracic and Vascular Anesthesia, 1992This study evaluated arterial catheter oximetry versus pulse oximetry in eight patients (ASA III-IV) who underwent cardiac surgery. Co-oximeter saturation values served as the standard. Arterial oxygen saturation was determined simultaneously with these three methods at 162 prospectively defined points of measurement before, during, and after ...

We now have the technology through reflectance spectrophotometry to evaluate and display continuously mixed venous oxygen saturation SvO2 through use of a modified pulmonary artery catheter. Adding this method of assessing the balance of oxygen supply and demand to our standard armamentarium of hemodynamic monitoring may improve our ability to diagnose

Chest, 2015
We read with great interest the article by Aldrich et al 1 in this issue of CHEST (see page 1484 ). In 2003, we reported our trial of measuring noninvasive arterial saturation during a pulseless situation (cardiopulmonary bypass [CPB]) by inducing a simulated pulse.

Current Opinion in Obstetrics and Gynaecology, 1998
Within the last ten years several groups adapted pulse oximetry to be used in the fetus. The obvious advantage of this technology is the fact that a biochemical parameter--the arterial oxygen saturation--can be measured continuously during delivery. Nevertheless, the continuous information about the fetal oxygenation during delivery has a couple of ...

MR oximetry includes methods for assessing tissue oxygenation. This chapter focuses on direct measurements of oxygenation. These can be divided into three methods. The first and most common has been termed BOLD MRI and relates to the quantification of deoxyhemoglobin.

Retinal oximetry is a noninvasive method to evaluate retinal oxygen consumption. By fundus photography at different wavelengths, the differences in light absorption between oxyhemoglobin and deoxyhemoglobin can be used to calculate the retinal arteriolar and venular oxygen saturation as well as the arteriovenous oxygen saturation difference, which can ...
