You have arrived at the correct location if you are searching for a fitness tracker or wristwatch that comes equipped with a pulse monitor already installed. Most smartwatches and fitness trackers made in the last few years have an optical heart rate monitor.
In this piece, we will take a look at some of the top fitness trackers and smartwatches on the market right now, including those that also have a built-in pulse oxygen monitor (also known as a pulse oximeter).
Blood saturation became a parameter in discovering the coronavirus in our bodies. The truth is that many smartwatch and fitness tracker manufacturers had incorporated oxygen sensors (oxygen sensors/monitors) into their watches and fitness trackers long before this virus showed up. Blood saturation became a parameter in the discovery of the coronavirus in our bodies.
How accurate are the oxygen monitors that are built into modern smartwatches and fitness trackers? To what extent can I put my faith in medical devices? Are they accepted by the FDA?
Within the scope of this text, I will talk about these vital aspects.
The vulnerability in the Pulse Ox Sensor found on the widely used Garmin Vivosmart 4 Covid 19 has already spread to more than half a million users throughout the globe, and its scope is fast expanding. So far, it has spread to more than 199 nations across the globe and several governments have issued medical emergencies and lockdowns to curb the spread of this unique coronavirus. The good news is that these steps have helped the governments to flatten the curve to some extent. However, the World Health Organization (WHO), the Centers for Disease Control and Prevention (CDC), and other health agencies still recommend taking extreme precautions to avoid contracting the infection.
The SARS-CoV-2 coronavirus infects the lungs, resulting in severe pneumonia that makes it difficult for the patient to breathe. According to the World Health Organization (WHO), having a low oxygen saturation level is one of the signs that might indicate you have the COVID-19 virus, which means that you should seek medical attention as soon as possible.
The sleep oxygen sensor may help you detect “sleep apnea,” which is a very significant sleep issue, and it can also assist you with your training progress. Both of these benefits are in addition to its ability to help you find the coronavirus.
Here is a short video explanation from Garmin.
I will share all you need to know about blood oxygen levels in this detailed guide that I have put up for you. I will also discuss some of the most useful smartwatches and other wearable devices that may assist you in determining the amount of oxygen in your blood. Let’s get into it.
The Best Smartwatches And Fitness Trackers With An Oxygen Sensor (SPO2)
What exactly is the pulse oximetry test?
Pulse oximetry is the method that is used to determine the amount of oxygen that is saturated in the blood (SO2). Pulse oximeters are most often used in clinical settings as well as hospitals.
As its name suggests, a pulse oximeter is a device that combines the functions of a pulse meter with an oxygen monitor.
There are primarily two different sorts of procedures that are used for determining the oxygen saturation of a given space.
“SPO2.” Peripheral oxygen saturation (SPO2) is abbreviated as “SPO2.” This is a roundabout method that does not involve any intrusion. The pulse oximeter is what we will be using for this strategy.
SAO2 stands for arterial oxygen saturation and is expressed as a percentage.This method is not only straightforward but also intrusive. In this technique, your doctor will perform a blood test on you called an “Arterial Blood Gas Study” to determine the percentage of oxygen that is already present in your blood.
Most modern smartwatches have an SPO2 sensor that lets the device figure out how much oxygen is in the blood of the wearer.
You must be curious about the operation of the pulse oximeter at this point. The following is what the American Thoracic Society has to say about it:
A pulse oximeter may be purchased as a compact unit that already has a clip for your finger or toe built in, or as a small portable gadget that includes a probe that can connect to or be applied to your finger, toe, or earlobe. In order to determine the amount of oxygen in your blood, the gadget sends a beam of light through your finger (or earlobe, or toe).
The smartwatches work the same way as the traditional finger clip, except that the light comes from the wrist instead of the finger.
Pulse oximeters display the amount of oxygen in the blood as a percentage. This is how they measure blood saturation. On the other hand, it can be different depending on the seller. For instance, the oxygen saturation level is shown by Fitbit as a graph, which is something that will be covered in more detail later on in this article.
Why do we need it, and who makes use of it?
Pulse oximeters, also known as oxygen sensors, are instruments that medical professionals use in order to ascertain the extent to which oxygen is saturated in the blood of their patients. Because oxygen is so essential to the functioning of our bodies, you may think of it as a necessary gas. Without oxygen, we simply would not be able to live.
The lungs are important because they allow people to take in oxygen, which is then sent through the bloodstream, starting in the blood and ending in the cells, to all parts of the body.
Pulse oximetry is used by medical professionals to assess whether or not a patient has a lung condition by measuring the patient’s oxygen saturation levels. When a patient has any kind of lung illness, their oxygen saturation values drop.
This test is used for a wide variety of different medical illnesses as well as lung disease. Some examples of these disorders are asthma, pneumonia, lung cancer, anemia, and heart attacks. Doctors utilize this test to diagnose patients with these and other conditions.
The Ideal Concentration of Oxygen in the Blood
The method of determining the amount of oxygen saturation in the blood by the use of a pulse oximeter is referred to as “O2 Sat” in the field of medicine (SPO2). The following recommendations will assist you in determining your oxygen saturation level and whether or not you need to make an appointment with a medical professional. We will do our best to keep the words as straightforward as possible.
If your reading is between 95 and 100 percent, everything is fine.
If your reading is less than 95%, it is considered low, and you should see your primary care physician as soon as possible.
In those infected with the coronavirus, the most important symptom is a severe episode of pneumonia. Patients who are diagnosed with severe pneumonia have an oxygen saturation (SPO2) that is lower than 90 percent while they are breathing room air, as stated in the WHO interim guidance paper on coronavirus.
What Kind of Accuracy Can You Expect From Finger Pulse Oximeters?
The American Thoracic Society says that the oxygen level from a finger pulse oxygenimeter, such as the ones that are used in medical facilities, is relatively accurate. The majority of finger oximeters provide a value that is either 2% higher or 2% lower than your saturation would be if measured with an arterial blood gas (ABG).
In the same paper, there is another passage that states, “The oxygen reading may be less accurate if a person is wearing nail paint or artificial nails, has chilly hands, or has poor circulation.”
Finger pulse oximeters’ accuracy can be changed by a number of things, some of which are listed below.
What Kind of Accuracy Can You Expect From the Pulse Oximeter Sensors in Smartwatches? Do I have the ability to put my whole trust in them?
My cheap LetsFit smartwatch could test how much oxygen was in my blood, and the results were about the same as those from my more expensive watches.
Despite the fact that smartwatches and other wearable devices are going to play a significant part in the future of the medical business, there have already been a number of instances in which smartwatches have been instrumental in preventing deaths.
When it comes to the SPO2 sensors in smartwatches, which imply that they are reading the SPO2 from the wrist, their accuracy is not that great, and it relies on a number of different circumstances.
Because smartwatches measure your SPO2 from your wrist, several factors, such as skin tone, fat levels, blood vessels, correct wearing, and suitable straps, will all have an effect on the results.
In addition, in contrast to the VO2 Max test, which evaluates the amount of oxygen in your blood while you are exerting yourself, the SPO2 measurement has to be conducted when you are sitting totally still and in a state of complete relaxation. Any movement or effort you make before or during the test will have a significant impact on the results.
Having said that, you absolutely can not put your life in their hands since they are not trustworthy.
Talk to a doctor if you are having health problems or if you don’t know how your health is right now.
These devices are not intended to take the place of a thorough medical examination.
Using the finger and the wrist, compare oxygen levels in the blood.
Zacurate Pro Series 500DL Fingertip Pulse Oximeter
You’ll remember it after reading these words from Conor Heneghan, who is the director of research at Fitbit:
“Measuring SpO2 on the wrist is a rather difficult technological challenge.” Unlike the fingers, which have numerous blood veins near the surface and produce a strong signal, the wrist is prone to blockages and poor readings. If “you move a little bit,” or even if “you are just a little bit cooler than usual,” you might receive a very faint signal, Heneghan said. “We’ve gone for long-term averaging so that when we take nightly measurements, we can confidently reject the times when we believe the signal is too loud or too faint to be trustworthy.”
Because of this, the Fitbit will only assess your SPO2 levels when you are sleeping and will provide you with an overnight evaluation. This is in contrast to the Apple Watch 6, which does spot checks both while you are awake and while you are asleep.
Are pulse oximeters that are worn on the finger or that are integrated into smartwatches FDA-approved?
Although the FDA has certified a number of different brands of finger pulse oximeters (Medline, for example), none of the smartwatches have received this certification.
Should I then buy a smartwatch with an oxygen sensor, knowing that I can’t rely on its accuracy?
To answer that, it really depends on what your expectations are.
If the only reason you need a reliable pulse oximeter is for medical purposes, you may get one from Medline that costs just fifty dollars and is authorized by the Food and Drug Administration.
If you want a smartwatch because it has a ton of functions, offers a lot of fun, and provides SPO2 readings that are fairly precise (particularly as a device for measuring blood oxygen levels overnight), then by all means, go for it. Smartwatches are excellent.
In addition to that, a number of customers have reported that the watches provide accurate SPO2 readings (even when spot-checked), and it is possible that they will function appropriately for you as well (providing that you wear them tight enough).
Consider purchasing an accurate finger-pulse oximeter from Amazon for an extra twenty to thirty dollars and comparing its readings to those from your watch. This might be an excellent answer.
If they are consistent with one another, you will know that your watch is functioning well for you and that you may now have a nice night’s rest while also monitoring your SPO2 levels.
You may be interested in another piece that I’ve published, which is linked here and discusses the top five devices that can be worn to monitor blood sugar or glucose levels.
Can a Garmin device monitor blood oxygen levels and, if so, how accurate are the readings?
Garmin is one of the most well-known corporations available, and the company recently included an oxygen sensor called “Pulse Ox” in the smartwatches and fitness bands that they manufacture.
The primary use of this sensor in Garmin watches is to identify “Sleep Apnea.” Sleep apnea is a sleep disease, and research has shown that eight out of ten individuals who have this issue are unaware that they have it.
The Garmin Pulse Ox sensor checks the amount of oxygen in the blood, and you can determine whether or not you have this issue based on the data it provides.
Garmin watches, similar to the Apple Watch 6, provide the wearer the ability to carry out a spot-on check-in, for which they are required to remain still for thirty seconds. In addition to that, it tracks the target throughout the night.
In the official part of the FAQ, it does state that “... [accuracy] may be impacted by altitude, exercise, and an individual’s health.” This is in reference to the accuracy of the device.
In addition, the passage suggests that an inappropriate posture may be to blame if the reading on your pulse oximeter while you are sleeping seems to be sluggish. Maintaining a posture that is “conducive to excellent circulation and at or near heart level” is something that the website suggests doing.
Can Fitbit tell how much oxygen is in the blood, and if so, how accurate are the readings?
The SPO2 sensor, which is included in many Fitbit smartwatches and fitness bands (some of which are noted in the list that follows), is primarily geared at addressing the issue of sleep apnea. Instead of showing the percentage value, Fitbit shows a graph that shows the “Estimated” difference in oxygen levels.
The graph draws attention to the significant variety that exists within the graph, which may be an indication that there is a problem. Nevertheless, this is not a real SPO2 estimate that has been calculated.
“We are not proposing that this [graph] can be utilized to correlate with sleep apnea status,” said Dr. Conor Henenghan, Fitbit’s Lead Sleep Research Scientist. This graph presents us with another chance to extend the amount of information that we provide to our visitors.
In addition to this, he said that “seeing frequent significant fluctuations is an indication that you may be suffering from sleep deprivation—something you would want to speak about with your doctor.”
How accurate is the pulse oximeter that comes with the Withings device?
Withings has also just introduced a product called “ScanWatch,” which is similarly geared at treating sleep apnea. The SPO2 sensor, which can monitor the blood oxygen level and offer warnings about any possible concerns, is included with this product. At this time, we are still awaiting permission from the FDA.
Does the Apple Watch have the capability to detect blood oxygen?
There is a pulse oximeter included with the brand new Apple 6 model.
The Apple Watch 6 is able to execute spot-on tests, which will require you to remain absolutely still for 15 seconds and collect measurements. I have already indicated that this capability is available on the Apple Watch 6.
You may discover a specific “Pulse Oximeter” app for older versions of the Apple Watch on the App Store. This app makes use of the camera on the Apple Watch to measure your oxygen levels and pulse rate from your fingertip.
The Pulse Oximeter app, on the other hand, states that it is “not meant for medical use” and that it was “primarily created for general health and wellbeing reasons.”
This choice is not particularly accurate, so utilizing it is not something that I would suggest doing.
Is there a watch made by Xiaomi that has an oximeter?
There are a lot of fantastic smartwatches available from Xiaomi, but very few of them have an oximeter as a built-in feature (SPO2 Sensor). The Xiaomi Mi Watch is the first Xiaomi watch to have an oximeter in its set of features. The company’s premium smartwatch is equipped with a full-fledged and fully operational SPO2 sensor, which you can use to monitor the amount of oxygen in your blood.
Consider purchasing the Xiaomi Mi Band 6 if you are looking for a cheap option from Xiaomi that nevertheless offers an oximeter. In addition, this model has a built-in SPO2 sensor.
These are the 12 best fitness trackers and smartwatches that include an oxygen sensor.
If you have read all the way down to this point, then you already have a good deal of knowledge about the oxygen sensors. In the following paragraphs, we will discuss the top 12 smartwatches and other devices that have an oxygen sensor.

Questions That Are Typically Responded To [FAQs]
Does a Smartwatch Have the Capability to Accurately Measure Oxygen Levels?
The answer is that almost all of the main brands of smartwatches have a specific SpO2 sensor that can detect blood oxygen levels. You may even take readings while engaging in strenuous activities like working out.
What kind of accuracy can one expect from the oxygen sensor included in smartwatches?
The practical measurement accuracy is 2% within a range of 80 percent to 100 percent SpO2.When the SpO2 level is maintained between 50 and 80 percent, the accuracy drops to 3%.
Is it possible to use a smartwatch instead of a traditional oximeter to measure the amount of oxygen in the blood?
It is recommended that you continue to wear an oximeter so that the reading may be used for therapeutic reasons. Readings from an oximeter are known to be more reliable than those from a sensory smartwatch.
Why Is It Necessary For Me To Check How Much Oxygen Is In The Air?
The answer is that fitness-focused smartwatches provide access to a variety of premium health data. In order to do the calculations suggested, we need an approximation of your blood oxygen level.
That wraps things up, people. These are a few of the most impressive examples of smartwatches that have an oxygen sensor. Utilizing one of these watches will allow you to receive an estimate of your current blood oxygen level. However, these timepieces are not a suitable replacement for the medical equipment used by trained professionals. In the event that you are not feeling well, you should make it a priority to call the health hotline and get medical attention as soon as possible.
