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.

Sep 25, 2025 · Normal oxygen levels (SpO2) are between 95% and 100%, indicating an adequate concentration of oxygen in the bloodstream. Levels below 90% are low (hypoxemia) and may often …

Normal SpO2 values vary between 90 and 100%. Good blood oxygenation is necessary to supply the energy your muscles need in order to function, which increases during a sports activity. If your SpO2 …

SpO2, or saturation of peripheral oxygen, indicates the percentage of oxygen carried in your blood. This measurement reflects how effectively oxygen is transported throughout your body, offering insights …

Dec 18, 2025 · While pulse oximeter readings are a reliable measurement of oxygen saturation levels in people with SpO2 of 90% or higher, some research suggests it may be less accurate in moderate or …

SpO2, or peripheral oxygen saturation, is a measure of the percentage of oxygen-saturated hemoglobin in the blood compared to the total hemoglobin. In simpler terms, it indicates how effectively oxygen is …

Normal oxygen saturation levels (SpO2) are between 95 to 100 percent for both adults and children. Oxygen saturation levels below 95% are considered abnormal, and the brain may be affected when …

Jun 13, 2024 · 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%. SpO2 readings can fluctuate based on …

Pulse oximetry is a noninvasive method for monitoring blood oxygen saturation. Peripheral oxygen saturation (Sp O2) readings are typically within 2% accuracy (within 4% accuracy in 95% of cases) of …

Oxygen saturation (SpO2) indicates the percentage of hemoglobin in your blood carrying oxygen. Normal SpO2 readings typically range from 95% to 100% for healthy individuals.
