Normal oxygen saturation (SpO2) levels are between 95 and 100 percent for both adults and children.
However, older adults tend to have slightly lower oxygen saturation levels than younger adults and children.
People over the age of 70 may have oxygen levels closer to 95%, which may be normal for that age group, while normal SpO2 rates for infants and children are typically 97% or higher.
Modern pulse oximeters provide accurate and non-invasive measurements of arterial oxygen saturation. Such devices are simple to use, measure normal oxygen saturations accurately in most patients, and detect desaturations reliably under a variety of conditions.
Numerous studies document the utility of pulse oximetry in special patient subgroups while recent technical advances make low-cost routine screening possible.

The purpose is to examine how the patient’s heart rate and oxygen saturation change and then processed and displayed them in charts.
