Hemoglobin oximetry
WebAbstract Pulse oximetry is a major improvement in the assessment of oxygenation. The device uses plethysmography and light absorbance measurements at two wavelengths to estimate oxygen saturation. It is inaccurate, however, when more than two types of hemoglobin are present. Web1 dec. 2016 · Pulse oximetry measures arterial oxygen saturation based on the light absorption properties of blood. When it combines with oxygen, deoxyhemoglobin (Hb) changes its light absorption characteristics. Pulse oximetry exploits the light absorption difference between Hb and oxygenated hemoglobin (HbO 2).
