What does Spo2 mean? What does Spo2 stand for in Medical Terms?

SpO2 stands for oxygen saturation, an estimate of the amount of oxygen in the blood. More specifically, it is the percentage of oxygenated hemoglobin, oxygen-containing hemoglobin, compared to the total amount of hemoglobin in the blood, oxygenated and non-oxygenated hemoglobin.

The body needs a certain level of oxygen in the blood or it won’t work as efficiently. In fact, very low SpO2 levels can cause very serious symptoms. This condition is known as hypoxemia.

Hypoxemia, low oxygen levels in the blood, can turn into hypoxia, low oxygen levels in the tissue. It is important to understand this progression and the difference between the two conditions.

Normal oxygen level in oximeter

SpO2 can be measured using pulsimetry, an indirect and non-invasive method, which means that it does not involve the introduction of instruments into the body. It works by emitting and then absorbing a wave of light that passes through blood vessels, or capillaries, at the fingertip.

A variation in the light wave passing through the finger will give the value of the SpO2 measurement because the degree of oxygen saturation causes variations in the color of the blood.

This value is represented by a percentage. If your pulse says 98%, this means that each red blood cell is made up of 98% oxygenated hemoglobin and 2% non-oxygenated hemoglobin. Normal SpO2 values range from 90 to 100%.

Good oxygenation of the blood is necessary to supply the energy that the muscles need to function, which is increased during a sporting activity. If your SpO2 value is below 90%, that could be a sign of poor blood oxygenation, also called hypoxia.

Please note that it is advisable to use your device to measure your blood oxygen level when you are at rest, especially after physical activity. Also, be aware that low blood flow may prevent measurement or cause error. In this case, check that it is seated correctly and try again. Do not move or talk during the measurement.

What is oxygen saturation?

Oxygen saturation measures the percentage of hemoglobin bound to oxygen in the blood and is represented as arterial oxygen saturation (SaO2) and venous oxygen saturation (SvO2).

Oxygen saturation is a vital parameter in defining blood oxygen content and oxygen supply.

For adults, the normal range of SaO2 is 95 to 100%. A value less than 90% is considered low oxygen saturation, which requires an external oxygen supplement.

How to measure oxygen saturation in the blood?

The measurement of oxygen saturation is particularly important for patients with health problems that can reduce the level of oxygen in the blood. These conditions include chronic obstructive pulmonary disease (COPD), asthma, pneumonia, lung cancer, anemia, heart failure, heart attack, and other cardiopulmonary disorders.

The most common method for measuring oxygen saturation is pulse oximetry. It is an easy, painless, and non-invasive method in which a probe is placed on the fingertip or earlobe to indirectly measure oxygen saturation.

SpO2, also known as oxygen saturation, is a measure of the amount of oxygen-carrying hemoglobin in the blood relative to the amount of hemoglobin not carrying oxygen.

The human body needs a certain level of oxygen in the blood or it will not work as efficiently.

Very low levels of SpO2 can cause very serious symptoms.

This condition is known as hypoxemia. There is a visible effect on the skin, known as cyanosis due to the blue (cyan) tint it takes on.

Hypoxemia (low oxygen levels in the blood) can turn into hypoxia (low oxygen levels in the tissue). It is important to understand this progression and the difference between the two conditions.

What is a normal SpO2 level?

A normal oxygen level is usually 95% or more. Some people with chronic lung disease or sleep apnea may have normal levels of around 90%. The “SpO2” reading on a pulse oximeter shows the percentage of oxygen in a person’s blood. If the SpO2 reading at home is less than 95%, call your healthcare provider.

What is normal blood oxygen level?

Normal arterial oxygen is approximately 75 to 100 millimeters of mercury. Values under 60 mm Hg usually indicate the need for supplemental oxygen. Normal pulse oximeter readings usually range from 95 to 100 percent. Values under 90 percent are considered low.
A normal level of oxygen is usually 95% or higher. Some people with chronic lung disease or sleep apnea can have normal levels around 90%.
Hypoxemia is a below-normal level of oxygen in your blood, specifically in the arteries. Hypoxemia is a sign of a problem related to breathing or circulation, and may result in various symptoms, such as shortness of breath.
