Explained in simple terms
We are often asked, ‘what does Spo2 or SpO2 refer to?’ Or sometimes, ‘what does SpO2 mean, anyway?’ O2 stands for oxygen, of course. ‘Sp’ stands for the peripheral oxygen saturation in the blood. So the focus is on questions like these: What is the blood oxygen saturation level? How high should the blood oxygen saturation level be? How low can it be? Which SpO2 value is appropriate for newborns, for children and for adults? The level is measured by means of pulse oximetry, which is used in emergency services, intensive care units and anaesthesia as a non-invasive standard method of monitoring patients. Another field of application is, for example, sleep medicine. Here, measuring the blood oxygen saturation level is used to diagnose whether adults suffer from sleep apnoea and how this health problem affects the oxygen in the blood.
