Pulse oximetry is routinely used in hospitals in high-income settings, but its theoretical basis is often poorly understood. This paper summarises the physiological background, technological basis and limitations of pulse oximetry.

Effects of Methemoglobinemia on Pulse Oximetry and Mixed Venous Oximetry
Anesthesiology, 1989The performance of three commercially available pulse oximeters was assessed in five anesthetized dogs in which increasing levels of methemoglobin were induced. Hemoglobin oxygen saturation in each dog was monitored with three pulse oximeters (Nellcor N-100, Ohmeda 3700, and Novametrix 500) and a mixed venous saturation pulmonary artery catheter ...

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.

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

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.
