CO-oximeter - Wikipedia
WEBA CO-oximeter measures the absorption of light passing through blood from few as two or three wavelengths of light to several dozens of wavelengths, in order to distinguish oxyhemoglobin, and deoxyhemoglobin (formerly called 'reduced' hemoglobin), and thus determine the oxyhemoglobin saturation (the percentage …

What is CO-oximetry? - OpenOximetry
WEBThe term CO-oximetry refers to devices that use at least four wavelengths of light to measure not only oxy and deoxy-hemoglobin, but also other forms of hemoglobin (e.g. CO-Hb, Met-Hb).
CO-oximeter - an overview | ScienceDirect Topics
WEBCO-oximeters are multiwavelength spectrophotometers that measure the optical absorbance of blood at different wavelengths and automatically calculate the fractional concentration of the four major Hb species (oxy-, deoxy-, carboxy-, and methemoglobin) from a total Hb concentration.
Focus on Diagnosis: Co-oximetry | Pediatrics In Review
WEBFeb 1, 2007 · A co-oximeter is a blood gas analyzer that, in addition to the status of gas tensions provided by traditional blood gas measurements, measures concentrations of oxygenated hemoglobin (oxyHb), deoxygenated hemoglobin (deoxyHb or reduced Hb), carboxyhemoglobin (COHb), and methemoglobin (MetHb) as a percentage of the total hemoglobin concentration ...
Pulse oximetry - UpToDate
WEBPulse oximetry uses spectrophotometry to determine the proportion of hemoglobin that is saturated with oxygen (ie, oxygenated hemoglobin; oxyhemoglobin) in peripheral arterial blood. Light at two separate wavelengths illuminates oxygenated and deoxygenated hemoglobin in blood.

WEBDLCO is measured by sampling end-expiratory gas for carbon monoxide (CO) after patients inspire a small amount of carbon monoxide, hold their breath, and exhale. Measured DLCO should be adjusted for alveolar volume (which is estimated from dilution of helium) and the patient’s hematocrit.
WEBA CO-oximeter is a spectrophotometric device that measures relative blood concentrations of functional forms of hemoglobin, oxyhemo-globin (Hb) and deoxyhemoglobin (rHb), and dysfunctional forms of hemoglobin, carboxyhe-moglobin (COHb), and methemoglobin (MetHb). These analyses can be obtained from various instruments including laboratory
Pulse Oximetry and CO-Oximetry - Wiley Online Library
WEBJun 8, 2012 · Pulse oximetry and to some extent CO-oximetry have become firmly entrenched in the monitoring of anesthetized, acutely ill, and critically ill patients. This chapter focuses on the principles of oximetry and how to …
