WebJul 8, 2014 · Due to the discrepancy between the measurement of SaO2 by pulse oximetry and the invasive technique, the former is denoted as SpO2. Manufacturers of pulse oximeters generally claim an accuracy of 2%, evaluated by the standard deviation (SD) of the differences between SpO2 and SaO2, measured simultaneously in healthy subjects.
WebMar 10, 2016 · The normal range for PaO2 is between 80 – 100 mmHg The Oxy-Haemoglobin Dissociate Curve As cells use up the floating oxygen, the PaO2 begins to fall. To maintain an equilibrium, the haemoglobin unloads more oxygen (dissociates) to float in the bloodstream ready to be used by the cells. fight animeWebSpO2 is the oxygen saturation level per the pulse oximeter reading. SaO2 is the oxygen saturation reading per a blood gas analysis. Lastly, PaO2 is the partial pressure of the oxygen flowing from the alveoli to the capillaries and the vessels.
