WebSaO2 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. These are the key differences: SpO2. SpO2 is oxygen saturation measured using a pulse oximeter. Pulse oximetry, which is used to measure SpO2, is a noninvasive procedure. Web7 jul. 2024 · SpO2 is a measurement that represents the saturation of oxygen in our blood or, more technically, the amount of oxygen that is bound to hemoglobin cells within our …
WebPaO2 measurement may lead to inappropriate therapy if attempts are made to normalise PaO2, despite adequate SaO2/ SpO2 values; PaO2 differences in sequential ABGs are often due to random variation, according to Mallat et al (2015) only a PaO2 difference of +/- 9 mmHg between measurements should be considered real. An arterial blood gas (ABG) test, or arterial blood gas analysis (ABGA) measures the amounts of arterial gases, such as oxygen and carbon dioxide. An ABG test requires that a small volume of blood be drawn from the radial artery with a syringe and a thin needle, but sometimes the femoral artery in the groin or another site is used. The blood can also be drawn from an arterial catheter.
