Why these three groups of people need pulse oximetry?

SpO2 stands for peripheral capillary oxygen saturation, an estimate of the amount of oxygen available in the blood. Good blood oxygenation is necessary to supply the energy your muscles need in order to function, which increases during a sports activity. And pulse oximetry is a non-invasive method that enables the measurement of a person’s SpO2 to monitor a person’s respiratory function and to determine whether a person suffers from hypoxia.

As it known to all, human cannot live without oxygen. By testing SpO2, you can see the oxygen supply and assess health condition of a body, disease severity, therapeutic effects and rehabilitation. So SpO2 index plays a monitoring role in disease prevention, therapy and rehabilitation exercise.

These three groups of people should have pulse oximeter and check SpO2 periodically.

Family members

In household environment, pulse oximetry can help people (especially old people) with heart attack, hypertension or diabetes to monitor respiratory and immunity system by testing SpO2 index. Also, pulse oximetry can monitor the curative effect of people who suffers from respiratory diseases. For example, snoring for a prolonged period or using respirator. Moreover, for people who live in a closed environment, especially in winter when burning coal for heating, checking SpO2 can give an early warning to prevent them from CO poisoning and starving oxygen.


If you are a businessman and travel on business or work overtime very often, your brain and body may undergo high consumption and low intake of oxygen, which is very harmful for brain and myocardium. An oximeter is essential for them to monitor SpO2 condition and schedule the time properly.

Outdoor enthusiasts

People go to the gym very often need to adjust exercise intensity based on their physical condition. Monitoring SpO2 can provide protective measures when doing exercise. If you are a mountain climber or an athlete training in high altitude to boost your endurance, measuring your blood oxygen saturation is very relevant as it can bring light to potentially life-threatening hypoxic conditions.
