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 check if someone’s blood …

Pulse oximetry is a method used to estimate the percentage of oxygen bound to hemoglobin in the blood. [10] This approximation to SaO 2 is designated SpO 2 (peripheral oxygen saturation).

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 …

Apr 8, 2025 · SpO₂ is an abbreviation for Peripheral Oxygen Saturation, which is a way of saying “how much oxygen is in your blood.” This value is shown as a percentage, representing how much oxygen …

What does SpO2 mean? What is a normal SpO2 level? SpO2 stands for peripheral capillary oxygen saturation, an estimate of the amount of oxygen in the blood.

Dec 5, 2025 · SpO2 stands for Saturation of Peripheral Oxygen. This acronym is frequently seen on patient monitors and home devices. This measurement provides a rapid, non-invasive assessment of …

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 …

Mar 9, 2025 · SpO2, or peripheral oxygen saturation, measures the percentage of oxygen carried by your red blood cells. It reflects how well oxygen binds to haemoglobin, the protein responsible for …

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.

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, and options are …
