The normal oxygen saturation (SpO2) range of a healthy adult man is between 95% to 100%.Measuring oxygen saturation (SpO2) by a pulse oximeter device is a non-invasive procedure. Pulse oximeter device clip onto a finger and passes light through blood of the finger and measures the oxygen level.A pulse oximeter is a device used to measure the oxygen saturation level in the blood.Ī pulse oximeter is an electronic device which used to measure oxygen saturation in the blood. So, it is very important to measure the oxygen level in some critical health issues or to maintain a healthy lifestyle. SpO2 indicates the percentage of oxygen present in the haemoglobin. The amount of oxygen carried by the haemoglobin in the blood is known as oxygen saturation which also termed as SpO2. But in some cases normal oxygen level in the blood gets decreased which leads to hypoxemia (low oxygen level in the blood). In the human body, oxygen is carried by haemoglobin which is present in the blood. Oxygen is an essential component to maintain physiological functions in our body.
