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 …

Dec 5, 2025 · For a healthy adult at sea level, a normal SpO2 reading falls between 95% and 100%. This range indicates that the lungs are performing gas exchange efficiently and the …

Peripheral oxygen saturation (SpO 2) is typically measured at a fingertip using a pulse oximeter. Pulse oximetry is a method used to estimate the percentage of oxygen bound to hemoglobin in …

Feb 18, 2022 · An oximeter reading only indicates what percentage of your blood is saturated with oxygen, known as the SpO2 level, as well as your heart rate. It’s a quick and harmless way to …

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 …

Jun 13, 2024 · Your blood oxygen level—sometimes referred to as SpO2—measures how much oxygen is circulating in your bloodstream. There are many ways to measure blood oxygen, …

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 …

SpO2 is the functional oxygen saturation measured by pulse oximetry. A normal SpO2 reading is usually considered to be above 94%. An SpO2 of 90-94% can signal that a patient may have a …

Oxygen saturation (SpO2) represents the percentage of hemoglobin binding sites occupied by oxygen molecules in your bloodstream. This measurement indicates how efficiently your …

A pulse oximeter and blood oxygen saturation monitor is a non-invasive device that measures the oxygen saturation level (SpO2) in your blood and your pulse rate.
