What To Know

  • However, some Fitbit models, such as the Fitbit Versa 3 and Fitbit Sense, have a built-in SpO2 sensor that can estimate oxygen saturation levels.
  • The accuracy of the Fitbit SpO2 sensor is not as high as a medical-grade pulse oximeter.

Oxygen saturation, also known as SpO2, is a measurement of the amount of oxygen carried in the blood. It is an important indicator of overall health and can be used to detect a variety of conditions, including respiratory problems and heart disease.

Fitbit devices do not directly measure oxygen saturation levels. However, some Fitbit models, such as the Fitbit Versa 3 and Fitbit Sense, have a built-in SpO2 sensor that can estimate oxygen saturation levels.

How Does the Fitbit SpO2 Sensor Work?

The Fitbit SpO2 sensor uses a technique called pulse oximetry to estimate oxygen saturation levels. Pulse oximetry works by shining a light through the skin and measuring the amount of light that is absorbed by the blood. The amount of light that is absorbed depends on the amount of oxygen in the blood.

How Accurate is the Fitbit SpO2 Sensor?

The accuracy of the Fitbit SpO2 sensor is not as high as a medical-grade pulse oximeter. However, it is still accurate enough to provide a general idea of your oxygen saturation levels.

What Factors Can Affect the Accuracy of the Fitbit SpO2 Sensor?

There are a number of factors that can affect the accuracy of the Fitbit SpO2 sensor, including:

  • Skin tone: The sensor may not be as accurate on people with darker skin tones.
  • Activity level: The sensor may not be as accurate when you are moving around.
  • Temperature: The sensor may not be as accurate when you are in a cold environment.
  • Altitude: The sensor may not be as accurate when you are at a high altitude.

How to Use the Fitbit SpO2 Sensor

To use the Fitbit SpO2 sensor, you need to wear your Fitbit device on your wrist. The sensor is located on the back of the device.

To take an SpO2 reading, open the Fitbit app on your phone and tap on the “SpO2” tile. The app will then display your current SpO2 reading.

What Do the Fitbit SpO2 Readings Mean?

Normal SpO2 levels are between 95% and 100%. Readings below 95% may indicate a problem with your respiratory system or heart.

If you have a low SpO2 reading, you should talk to your doctor.

Troubleshooting Fitbit SpO2 Sensor Issues

If you are having trouble getting an SpO2 reading, there are a few things you can try:

  • Make sure that your Fitbit device is properly seated on your wrist.
  • Make sure that the sensor is clean.
  • Try taking a reading in a different location, such as your finger or earlobe.
  • If you are still having trouble, you may need to contact Fitbit customer support.

Final Thoughts

The Fitbit SpO2 sensor is a useful tool for tracking your oxygen saturation levels. However, it is important to remember that the sensor is not as accurate as a medical-grade pulse oximeter. If you have a low SpO2 reading, you should talk to your doctor.

Frequently Asked Questions

Q: Can I use my Fitbit to track my oxygen levels while I sleep?

A: No, the Fitbit SpO2 sensor is not designed to be used while you are sleeping.

Q: How often should I take an SpO2 reading?

A: You can take an SpO2 reading as often as you like. However, it is not necessary to take a reading more than once a day.

Q: What are the symptoms of low oxygen saturation levels?

A: Symptoms of low oxygen saturation levels can include shortness of breath, rapid heart rate, and confusion.
