Recent evidence suggests that pulse oximetry more frequently fails to detect hypoxemialow blood oxygen levelsin Black patients as compared to white patients. This measurement is known as the Sp02 - the saturation of peripheral oxygen - and it is an estimate of the Sa02 - the saturations of arterial oxygen. It is important to monitor your blood oxygen levels regularly and take steps to maintain healthy levels. COVID-19 Lung Damage. in the blood is an indicator that requires periodic monitoring in all elderly people. , which are characterized by a change in its qualitative or quantitative composition (for example, anemia). . ] Normal oxygen saturation levels (SpO2) are between 95 to 100 percent for both adults and children. Normal blood oxygen levels range from 95% to 100%, and anything below 90% is considered low. There are many different conditions that can cause low oxygen saturation levels, which may include: Low oxygen saturation levels (hypoxia and/or hypoxemia) are diagnosed with a physical examination. All organs require oxygen for metabolism but the brain and heart are particularly sensitive to a lack of oxygen.
