How Pulse Oximetry Devices Work

A pulse oximeter works in a very simple way. By just clipping the device onto your finger, a light from the oximeter is emitted into your finger. The emitted light has two different wavelengths of light that are absorbed by the oxygen molecules and hemoglobin that they are attached to and measured by a sensor on the other side.

If the sensor is calibrated correctly, it can distinguish how many hemoglobin cells are in the blood that is passing the nearest artery and how many of the cells have an attached. This reading is called your peripheral capillary oxygen saturation also known as SpO2.

Benefits of Using a Pulse Oximeter

Fitness Monitoring

If you have ever been out of shape, you know how difficult it can be to maintain oxygen levels when you have sudden heavy physical demands placed on your body. When you use a pulse oximetry device when you work out, you can push your body farther without worrying out about getting sick or placing your body to the point of complete exhaustion.

High Altitude Sports

Athletes in high altitude sports run the risk of oxygen deprivation so it is important to make sure you are aware of issues before they become a serious health problem. This includes sports like hang gliding, skydiving, or mountain climbing where being able to determine arterial blood oxygen levels is important and could save your life.

COPD Management

Those that suffer from COPD where their lungs have become damaged and their body can no longer make repairs. With this condition, it is important to monitor blood oxygen levels to know when your lungs aren’t giving you enough oxygen and therapy or medication may be needed.

Asthma Patient Care

Asthma attacks can also be debilitating and a pulse oximeter can let you know when your airways are becoming restricted before it becomes a serious issue. This allows you to use your inhaler before and asthmas attack happens.

Pulmonary Patients

There are also other rare pulmonary conditions that affect the lungs and are life-threatening. A pulse oximeter can benefit these patients by alerting them to changes in their arterial blood oxygen levels a serious complication happens.

Low Maintenance

After they are calibrated, a pulse oximeter will work the same for the next few years. After a startup check has been performed, their circuitry is never needed again.

Low Cost

A pulse oximeter is usually very affordable with few costing over $50. Plus, the majority will come with a warranty. This makes the pulse oximeter one of the least expensive home health monitor devices you can find.

Less Invasive Than Blood Gas Testing

The less invasive the better for most people, especially if the thought of needles causes them anxiety. Although it can’t tell you what your carbon dioxide levels are, a pulse oximeter can confirm if your oxygen levels are low when you are not feeling well letting you know it might be time to head to the hospital for treatment.

Accurate Pulse Reading

If you have been counting your heartbeat with your two fingers, you are probably not getting the most reliable results. A pulse oximeter can give you more accurate and reliable results, especially if you are having serious issues like a racing heart or overexertion.

How to Use a Pulse Oximeter Properly

Although oximeters are very easy to use, there are certain things you should avoid to make sure you get the best reading possible:

• Fingernail polish can hinder getting a correct reading, you may want to use an earlobe.
• Make sure to take your readings where there are low-light or normal conditions and avoid sunlight and bright overhead lighting.
• Don’t move while you are testing since body movement including sneezing and shivering can affect getting a correct reading.

Remember that if you have circulatory or respiratory conditions, the readings you get from your pulse oximeter will need to be interpreted differently. You can find that information with the device’s user manual.

And, always make sure to talk to your healthcare provider to on how to use the results you get from your pulse oximeter to correctly determine what is going on with your health.

What to Look for in a Pulse Oximetry Device

Accuracy

As you are shopping, you will want to find a pulse oximeter that is guaranteed within 2% (plus or minus) of actual SpO2 levels. It also needs to be accurate up to 70% oxygen saturation. This means that even if your arterial oxygen levels aren’t perfect, the pulse oximeter is still giving an accurate reading and you will know if you need to seek medical attention.

Warning Systems

You will also want to look for three warning systems that include:

• Irregular Heartbeat – a warning alarm should sound if your heartbeat isn’t constant and steady including any heart arrhythmias that may be of concern.
• Low SpO2 – even though you will see a low number on the screen, you should also have a warning beep for low SpO2 concentrations. Especially since you can also have blurred vision or dizziness when you are suffering from inadequate O2 concentrations.
• Low Battery – this is also important, so the battery won’t just die when you don’t expect, especially for those that rely on an oximeter for disease management.

Portability

Being able to carry your device with is important for most people who need to monitor their SpO2 with an oximeter. Those using it because they are a pilot or sports enthusiast, it is still handy to have the device in your pocket or around your neck.

Lightweight

Since you are looking for portability, having a unit that may be small in size but heavy and uncomfortable to use doesn’t make it a great device to take with you all the time. A lightweight unit may be easier for you to carry on you, especially on a handy lanyard. Keep in mind though that the weight of the oximeter does affect how durable it is, especially since heavier units can get damaged when they are accidentally dropped.

Durability

The difference between a cheap piece of equipment and something very durable can also mean the difference between life and death. You want a pulse oximeter that is durable enough to take a drop to the ground, being immersed in water, or have protection against humidity. When a pulse oximeter is damaged in any way, it can fail or give you inaccurate readings which can be life-threatening.

Fitment

If you have large fingers, an adjustable oximeter is a great choice, especially if you find non-adjustable units uncomfortable. You may find that you have to squeeze too hard or not hard enough with non-adjustable oximeters. With an adjustable brand, you are able to choose your comfort level so you aren’t dreading have testing throughout the day.

Automatically-Activated

Devices that turn on automatically when you insert a finger or toe is helpful, especially if you are weak from a low oxygen level and monitor your Sp02 frequently meaning the difference between life and death in some cases.

Bright Visible Display

Having a backlit display and font color combinations are great features to have in a pulse oximeter so you can see in the bad light. Adjustable brightness helps to work in any lighting condition while displays that have multiple viewing angles are very convenient so you aren’t straining to read the device.

Conclusion

Since a pulse oximeter is incredibly accurate and inexpensive, having the ability to check your pulse and Sp02 at home is a no-brainer. Especially for those suffering from potential health problems, monitoring your heart rate and oxygen levels can make a big difference in how large a serious medical condition can become. This handy tool could mean the difference between taking some medication or ending up in the hospital for an extended stay.

Your Fitbit smartwatch uses sensors to estimate your blood oxygen saturation (SpO2) while you sleep.

The Fitbit SpO2 feature is intended for general wellness purposes only and should not be used or relied on for any medical purposes. Consult your health care professional about any questions or health issues you may have.

Your blood oxygen saturation (SpO2) is the percentage of your blood that’s saturated with, or contains, oxygen. The oxygen levels in your blood tend to remain relatively constant, even during exercise and sleep.

Add SpO2 to your Fitbit device

To collect SpO2 data, install an SpO2 clock face (available on Ionic, Sense, and Versa series) or the SpO2 app (available on Sense and Versa 3).

The Fitbit SpO2 app is automatically added for users in select countries. For more information on updating your tracker, see How do I update my Fitbit device? For more information on the availability of Fitbit SpO2, see fitbit.com.

If you removed the SpO2 app from your device, reinstall it in the Fitbit app on your phone:

1. With your Fitbit device nearby, in the Fitbit app, tap the Today tab > your profile picture > your device image.
2. Tap Apps > All Apps.
3. In the list of apps, tap SpO2 > Install.

See your most recent SpO2 levels on your device

See your nightly SpO2 data on an SpO2 clock face:

1. Wear your Fitbit device to bed, and sync it in the morning.
2. Check your clock face to see your average SpO2 level and the range of values detected.

It may take around an hour for your SpO2 values to appear on the clock face after you sync your device. The clock face shows data for your most recent sleep session. If your sleep session is split into 2 separate logs or you take a long nap, the clock face updates to show data for the most recent sleep session after your device syncs with the Fitbit app.

1. Wear your Fitbit device to bed. Wear your device securely so that the back of your device is in contact with your skin.
2. In the morning, swipe up from the clock face. See your average resting SpO2 level on the SpO2 tile.

It may take around an hour for your SpO2 values to appear after you wake up. The SpO2 tile shows data for your most recent sleep session. If your sleep session is split into 2 separate logs or you take a long nap, the tile updates to show data for the most recent sleep session.

Track your SpO2 trends in the Fitbit app

See your SpO2 trends in the Health Metrics tile in the Fitbit app on your phone. The Health Metrics tile is available with Fitbit Charge 4, Fitbit Sense, Fitbit Versa 2, and Fitbit Versa 3. To see historical data, upgrade to Fitbit Premium. For other devices, a Fitbit Premium subscription is required to see health metrics data.

1. Wear your device for at least a full day, including to sleep at night.
2. In the morning, open the Fitbit app and tap the Health Metrics tile.
3. Swipe up to find the Oxygen Saturation (SpO2) tile.

Note that for Ionic, Versa, Versa Lite Edition, and Versa 2, SpO2 data is only collected when you use an SpO2 clock face. For a list of compatible SpO2 clock faces, see Add SpO2 to your Fitbit device. For Sense and Versa 3 you can install either an SpO2 clock face or the SpO2 app to collect SpO2 data. Charge 4 users must have the SpO2 app installed.

Your Fitbit device measures your SpO2 levels while you sleep using red and infrared sensors on the back of the device. The sensors shine red and infrared light onto your skin and blood vessels, and use the reflected light that bounces back to estimate how much oxygen is in your blood:

• Richly oxygenated blood reflects more red light than infrared light.
• Poorly oxygenated blood reflects more infrared light than red light.

Note that you might see the red and infrared sensors continue to blink for around 30 minutes after you wake up.

SpO2 values naturally vary, and nighttime SpO2 is usually lower than daytime SpO2 due to the fact that your breathing rate is usually slower during sleep. In general, SpO2 values during sleep are typically above 90%. The SpO2 values presented are an estimate and in general can be influenced by your activity, altitude, and overall health.

You may notice an SpO2 value that seems lower than expected. This can be due to:

• Your arm position and movement
• The position and fit of your Fitbit device
• Limited blood flow to the surface of the skin
• Differences in anatomical body structures can also impact the accuracy of your Fitbit device’s sensors.

Several factors can affect your body's ability to maintain blood oxygen levels. These include, but are not limited to, the following:

• There must be enough oxygen in the air you are breathing.
• Your lungs must be able to inhale air containing oxygen and exhale carbon dioxide.
• Your bloodstream must be able to carry oxygen throughout your body.

An issue with any of these factors could impact your SpO2 values. For example, in high altitudes the air is less dense and therefore contains less oxygen. If you experience low SpO2 values while at high altitudes you may want to consider descending to a lower altitude.

Certain health problems can also impact the body's ability to take in oxygen. These factors can be compounded under more extreme circumstances such as during intensive exercise.

You should not use or rely on the SpO2 reading on your Fitbit device for any medical purposes. If you have concerns about your health, you should consult your healthcare provider.

If you see the message “SpO2 not installed” on your clock face, install the SpO2 Tracker app. For instructions, see Add SpO2 to your Fitbit device.

If you see dashed lines on the clock face or SpO2 tile, a message that the SpO2 data couldn’t be read, or missing data in the Health Metrics tile in the Fitbit app on your phone, keep in mind the following:

• Your device doesn’t retroactively measure your SpO2 values. When you start using Fitbit SpO2, you’ll see dashed lines until after your next sleep session.
• You must get at least 3 hours of quality sleep. Data is only collected when you’re still. If you move a lot during your sleep or the sleep session is too short, you might not get SpO2 data.
• Charge your Fitbit device to make sure it’s able to collect data throughout your entire sleep session. Note that you may have to charge your Fitbit device more often when using an SpO2 clock face or app.
• You must sync your Fitbit device with the Fitbit app before the clock shows your SpO2 data. Note that it may take around an hour for your SpO2 values to appear after you sync your device. For troubleshooting syncing, see Why won't my Fitbit device sync?
• Turning off any SpO2 clock face or app permissions can cause the feature to stop functioning. For instructions on adjusting permissions, see How do I install and manage apps on my Fitbit device?
• Your Fitbit device must be able to consistently track your SpO2 data:
  • Wear your device slightly higher on your wrist.
  • Make sure your device is in contact with your skin.
  • Your device should be snug but not constricting.
  • Tattooed skin can impact the accuracy of the red and infrared sensors on your Fitbit device.

You may have to charge your Fitbit device more often when collecting SpO2 data.
