What is a normal oxygen level?

Normal: A normal ABG oxygen level for healthy lungs falls between 80 and 100 millimeters of mercury (mm Hg). If a pulse ox measured your blood oxygen level, a normal reading is typically between 95 and 100 percent.

However, in COPD or other lung diseases, these ranges may not apply. Your doctor will let you know what is normal for your specific condition. For example, it isn’t uncommon for people with severe COPD to maintain their pulse ox levels between 88 to 92 percent.

Below normal: A below-normal blood oxygen level is called hypoxemia. Hypoxemia is often cause for concern. The lower the oxygen level, the more severe the hypoxemia. This can lead to complications in body tissue and organs.

Normally, a PaO₂ reading below 80 mm Hg or a pulse ox below 95 percent is considered low. It’s important to know what is normal for you, especially if you have a chronicA condition or illness that arises slowly over days or weeks and may or may not resolve with treatment. It is the opposite of acute. lung condition. Your doctor can provide recommendations as to what ranges of oxygen levels are acceptable for you.

So what is the normal oxygen level? People who are breathing normal, who have relatively healthy lungs (or asthma that is under control), will have a blood oxygen level of 95% to 100%. Anything between 92% and 88%, is still considered safe and average for someone with moderate to severe COPD. Below 88% becomes dangerous, and when it dips to 84% or below, it’s time to go to the hospital. Around 80% and lower is dangerous for your vital organs, so you should be treated right away.

Your blood oxygen level will also go down a little when you are exercising unless your doctor has instructed you to turn your flow setting up while you are exercising, making up for this change. Depending on the model, your oxygen concentrator might also adjust to meet this need for more oxygen while you are physically active.
