Blood oxygen levels refer to the amount of oxygen circulating in the blood. Normal blood oxygen levels fall between 75 and 100 millimeters of mercury (mm Hg) on arterial blood gas (ABG) test results.

If your oxygen saturation level drops below 92%, seek medical help right away. A dangerously low oxygen level can make you ...

For most people, a normal pulse oximeter reading is between 95% and 100%, with readings below 90-92% generally considered low and requiring medical attention. They are known to be affected by several ...

Scientists have long known that pulse oximeters are less accurate when used for people with dark skin tones – and now, a new report offers some insight into just how much more inaccurate these ...

That’s where pulse oximeters come in. These small devices measure your heart rate and SpO₂. They give you another way to understand how your body responds during exercise and recovery. Also, they may ...

The differences, or bias, between estimates of blood oxygen saturation levels as measured with pulse oximeters compared to the gold-standard method of measuring oxygen saturation in arterial blood ...

Racially biased readings of oxygen levels in the blood using pulse oximeters may further limit opportunities for Black patients with heart failure to receive potentially lifesaving treatments, such as ...
