Using Blood Oxygen Level to Assess Breathing Quality
Your blood oxygen level—sometimes referred to as SpO2—measures how much oxygen is circulating in your bloodstream.
What is a dangerously low oxygen level
There are many ways to measure blood oxygen, and options are increasing with wearable health devices like smartwatches.
In this article, you will learn the ideal blood oxygen level range, when to get help, the accuracy of the different tools for measuring this vital sign.
What Blood Oxygen Level Tells You
Your blood oxygen level indicates how many red blood cells carry oxygen throughout the body. Ideally, 100% of these blood cells carry oxygen, but this isn't always the case.
A normal range for your blood oxygen level is between 92% and 100%.

Your body relies on a coordinated effort between your heart, lungs, and circulatory system to maintain a healthy blood oxygen level. Without an adequate amount of oxygen in your blood, you can develop hypoxemia, and your tissues can become damaged or destroyed.
