Nowadays, wearables are the latest technological innovation to capture various electronic and gizmos worlds. There has been a wide diversity in relation to the technological revolution and one of them is the Smartwatch.

It is an advanced watch that assists in tracking your health and fitness-related activities especially when you go for exercise or jog in the streets. But do you know what is spo2 in smartwatch?

Smartwatch Spo2 Monitor – A Potential Lifesaver

If you have been into smartwatches for a while, you may have heard of a term called oxygen saturation. This is not something new in the healthcare world.

Just like your blood pressure and heart rate, it has been available in spo2 supported smartwatches for a long time ago.

This is not something you should think much about because the smartwatch itself gives information about oxygen saturation through its high precision sensors.

To know the SpO2 in the smartwatch, you should know what is it. I’m sure you’ve already heard about SpO2 in health care when someone is under anaesthesia or intubated, but you may never hear it when people are conscious and healthy.

What is spo2 Feature in Smartwatch?

Like most people, you’re probably wondering what the heck SpO2 means. It’s a term for “blood oxygen saturation” and is a measurement of how well your body is absorbing and distributing oxygen.

It’s not usually measured but there are times when it might be useful — like if you have a blood sugar problem or if you’re pregnant.

When it comes to smartwatches, one of the most important sensors is a pulse oximeter sensor. Sometimes referred to as a SpO2 sensor, a pulse oximeter measures the amount of oxygen level in your bloodstream.

The thing that spo2 enabled smartwatches monitor is quite simple – it measures gas levels in your blood and sends the result to your smartphone.

What does Spo2 Level in Smartwatch Tell You?

The spo2 sensor tells you when your body needs rest after a workout, which ultimately makes you more efficient in terms of how you use your energy. These days, fitness bands are also coming with the spo2 feature.

Even though it’s helpful for athletes, the spo2 sensor should be used by everyone. It will tell you when to stop exercising and save your energy for another day.

Spo2 measuring smartwatches do it in percentages, and healthy levels range from 95 to 100 percent. At lower percentages, you may experience symptoms such as fatigue, chest pain or trouble breathing.

Your fingers and toes typically have lower Spo2 readings than other parts of your body. However, Spo2 readings taken from your fingertips are more accurate than those taken from your toes because your toes contain more dead tissue than other parts of your body do.

Why It is Important

A smartwatch’s measurement capabilities are still limited, but they are getting more advanced. SpO2 is one of the most important measurement parameters for periodic health monitoring systems.

It refers to the percent of haemoglobin that is saturated with oxygen (oxygenated) versus un-oxygenated haemoglobin (deoxygenated).

What is spo2 in Smartwatch & How it Works Is it Accurate

Is spo2 in Smartwatch Accurate?

The accuracy of a pulse oximeter is very important in determining blood oxygenation levels and pulse rate, particularly when comparing values against known standard values or ranges.

The spo2 sensor in a smartwatch is a great addition to a smartwatch because it keeps track of your physical performance and alerts you when you need to take a break from working out.

If an individual has poor health, he/she can use this sensor to get more information about what’s wrong with his/her body before consulting a doctor.

In conclusion, smartwatches with spo2 sensors are very useful devices that can help you stay healthy and live longer!

They can measure your blood oxygen levels. What does that mean? It means they’re a device that can tell you if you’re running a fever or have a respiratory problem.

Conclusion | spo2 Feature in Smartwatch

Smartwatches are some of the best fitness tracker watches. Smartwatches are meant to be used for health tracking with features like heart rates, SpO2 sensors, blood pressure tracking, and oxygen saturation levels along with other fitness-related metrics.

Needless to say, the smartwatch is now wearable technology that you’ll wear all the time. It’s an instant health tracker that’s always on hand.

It also collects information like heart rate, blood pressure and oxygen saturation levels registered through built-in optical sensors and monitors your vitals in real-time for you to make adjustments accordingly.

FAQs | Frequently Asked Questions

How does the spo2 Sensor work with the Smartwatch?

The SpO2 sensor works by measuring how much oxygen is in someone’s blood. It sends infrared light into the blood vessels of your wrist, then measures how much of that light is reflected back by haemoglobin.

Since haemoglobin contains iron, it absorbs more light than other tissue in the body, so it stands out to the sensor. The more haemoglobin in a blood vessel, the darker red it appears to the sensor.

The sensor figures out how much haemoglobin is present by calculating how much light is reflected back compared to how much was sent in. Based on this information, you can determine what your oxygen levels are and send that information to your watch for processing.

What are the Ideal spo2 Levels?

You can use the spo2 reading to determine whether there’s a risk that you may be having a medical emergency such as a heart attack or stroke. In general, it’s good to see over 95% of the oxygen in the blood but less than 100%.

The “sweet spot” is said to be 98-100%, although there are many factors that influence this number. Feel free to follow up with your doctor if you receive an alarmingly low reading.

It’s not uncommon to see lower levels when you’re active. however, if the number remains low after you’ve stopped moving for at least 10 minutes, it could be a sign of a problem. Spo2 levels also depend on the region of the body where they’re measured.
