Normal blood saturation level for adults Adults require high oxygen levels the same as children, so around 95 to 100 percent. , and it is dangerous to lose sight of critical changes. 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. What causes blood oxygen levels to become low?
