SpO2(oxygen saturation) is the fraction of
oxygen saturated haemoglobin relative to total
haemoglobin. It is important to estimate the
fitness level of an individual and is generally
expressed in percentage. SpO2(oxygen saturation)
is dependent upon various factors such as oxygen
availability, gas exchange in the lungs,
concentration of haemoglobin in the red blood
cells and the affinity of haemoglobin for oxygen.
The normal oxygen level of an healthy individual
lies between 95-100. Having normal saturation
level indicates that the body is getting
sufficient oxygen and the internal organs are
performing at their best. Having very low blood
oxygen level for a short time does not have
serious problem. But if it persists, it puts
stress on heart and brain and cause organ damage.

SpO2(Oxygen Saturation) is generally measured
non-invasively from the PPG signal obtained from
the fingertip pulse oximeter. People with chronic
conditions like asthma, heart disease and Chronic
Obstructive Pulmonary Disease (COPD) have
relatively low blood oxygen levels. They need to
monitor their oxygen levels to determine if their
treatments are working. Low blood oxygen levels
cause symptoms such as shortness of breath,
headache, restlessness, dizziness, rapid
breathing, chest pain, confusion, high blood
pressure, lack of coordination, visual disorders,
sense of euphoria and rapid heartbeat.
