Pulse oximetry is one of the most commonly applied technologies in acute and critical care. It has the potential to continuously monitor pulmonary function, avoid unnecessary blood gases, and alert clinicians to hypoxemic events that are not readily apparent by physical assessment. Due to these advantages, pulse oximetry has a firm place in health care.

Current Opinion in Critical Care, 2006
Mixed venous and central venous oxygen saturations reflect the balance between oxygen requirement and oxygen delivery, and thus may be used to assess the adequacy of tissue oxygenation. This review discusses recent data on the impact of using venous oximetry by obtaining mixed venous oxygen saturation or central venous oxygen saturation as useful ...

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].

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 ...

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 ...

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 ...

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 ...

This paper presents a method for automating the evaluation of hemoglobin oxygen saturation in the retina. This method should prove useful for monitoring ischemic retinal diseases and the effect of treatment. In order to obtain saturation values automatically, spectral images must be registered in pairs, the vessels of the retina located and measurement

Intrapartum Oximetry of the Fetus
Anesthesia & Analgesia, 2007Fetal monitoring during labor aims to identify fetal problems which, if uncorrected, may result in morbidity or death. A nonreassuring or abnormal fetal heart rate trace by cardiotocography (CTG) does not necessarily equate with fetal hypoxia and/or acidosis.

Pulse oximetry, a straightforward method for estimating arterial oxygen saturation, can detect hypoxemia early; it's used often and in a variety of settings. But what's not always clear is how frequently-or even whether-patients should be monitored, and unless guidelines are understood and followed, pulse oximetry can be misused or overused.
