Your blood oxygen level (blood oxygen saturation) is the amount of oxygen that's circulating in your blood. It can be measured with a blood test or a pulse oximeter.
Blood oxygen levels are indicated as SpO2, which is the percent saturation of oxygen in the blood. 95%-100%: Normal oxygen levels in a pulse oximeter usually range from 95%-100%. Note: Normal levels may vary if you have lung disorders. Your doctor can tell what levels are normal for you.
A normal range for your blood oxygen level is between 92% and 100%. SpO2 readings can fluctuate based on activity, overall health, and other factors. Your body relies on a coordinated effort between your heart, lungs, and circulatory system to maintain a healthy blood oxygen level.
A healthy blood oxygen level is 75–100 mm Hg, or 95–100%. Low blood oxygen levels, known as hypoxemia, may be a cause for concern.
Normal blood oxygen levels fall between 75 and 100 millimeters of mercury (mm Hg) on arterial blood gas (ABG) test results. A person’s blood oxygen level indicates how well the body...
Oxygen saturation levels (SpO2) between 95 to 100 percent are considered normal for both adults and children (below 95% is considered abnormal). People over 70 years of age may have oxygen levels closer to 95%.
For most healthy adults and children, a normal oxygen saturation level is between 95% and 100%. Hypoxemia occurs with lower levels of oxygen in the blood and can lead to complications or even death at dangerously low levels below 90%.
Normal blood oxygen levels in adults are between 95% and 100% oxygen saturation (pulse oximeter reading). See a healthcare provider if your at-home blood oxygen measurement is 93% to 94%....
A normal reading typically ranges from 95% to 100%. Levels below 92% are considered low and could indicate a more serious issue, so contact a healthcare provider. Seek immediate medical attention for a reading of 88% or lower.
A normal blood oxygen saturation level is in the range of 95–100%. If it falls below 91%, it requires immediate medical attention. Doctors consider a reading of 91–94% as borderline.
