If you’re recovering from a respiratory problem, chances are you may have had your oxygen levels checked with a pulse oximeter. Pulse oximetry is the non-invasive measurement of the oxygen saturation (SpO2). Oxygen saturation is defined as the amount of oxygen dissolved in blood, based on the detection of Hemoglobin, Hb, and Deoxyhemoglobin, HbO2. The typical pulse … [Read More...]
