How accurate is the samsung s10 oxygen sensor

There's a new wearable tech metric in town — and it's all about blood oxygen. It might sound complicated and a little pointless, but pulse ox can reveal conditions like sleep apnea — and help athletes recover.

And pulse ox is starting to appear on the spec sheets of the biggest names in wearables: Fitbit and Garmin already have an SpO2 sensor on most of their devices, and Withings has jumped in too. With set to be a big year for sleep tracking, you're certain to hear more about blood oxygen.

So why is putting a pulse oximeter inside of a wearable a big deal? We explore what it is, how it works and what it's going to bring to the wearable party.

When we talk about pulse oximeters or pulse oximetry, we are delving into the realm of medical tech and talking about a device that's able to measure oxygen levels or oxygen saturation in the blood, plus your heart rate. They can also be used to measure pulse rate too. That tech usually takes form of a clip-on device that you place on your finger, a toe or even on your ear lobe. It uses red and infrared light sensors to detect your oxygen levels, sensing changes in those levels.

It measures the volume of oxygen based on the way the light passes through your finger and delivers the data to the device's screen, which will tell you the percentage of oxygen in your blood. John Hopkins Medicine explains how measuring oxygen levels through pulse oximetry can offer insights into a range of health related issues. It can be used to check whether someone needs assistance with their breathing via a ventilator, measure a person's ability to handle intensive physical activities and it can also check whether breathing stops during sleep.

This is particularly relevant to sleep apneaa disorder which if left untreated or undetected could lead to an increase in the risk of high blood pressure, obesity and can even cause a heart attack. It can also be a valuable piece of health data for people suffering from a range of conditions including asthma, pneumonia, heart failure and lung cancer.

The first oxygen saturation meter is said to be from as far back as the s, when the exploration of light transmission through skin and the information it could provide really began. It wasn't until the s and 70s when we began to see the pulse oximeter devices shape into the ones that are now used in hospitals, and which can be purchased to carry out those measurements from your home.

Hewlett Packard was the first company to make an ear oximeter, which was largely used inside of clinical sleep labs due to its hulking size. But it was Japanese bioengineer Takuo Aoyagi, in the early s, who first developed a noninvasive way of using the light transmitted through the ear and went on to develop a pulse oximeter. From then up until today, the size of the tech has become smaller and — crucially — cheaper to build, so more people were able to get their hands on it.

Pulse oximeters are starting to find their way into some big name wearables and that data is being used in very different ways. Arguably it started with the Withings Pulse Ox fitness tracker, which measured blood oxygen levels when you placed your finger on the sensor on the back of the device.

But things have changed since then, and now the process of taking those measurements happen much more easily from the wrist. In this instance the on-screen widget will offer a blood oxygen percentage, coupled with data on your altitude, to show the levels of oxygen in the blood.

This is particularly useful for anyone that's into hiking, alpine sports and going on big expeditions. With elevation data you can view how oximeter readings are changing relative to your elevation. However, many wearables use pulse ox for a different reason: sleep apnea. This can cause adverse health effects.You may have noticed pulse oximeters getting a lot of press recently in light of coronavirus. But what do they do and what's the connection with the ongoing pandemic?

In a New York Times articleUS doctor Richard Levitan argues that pulse oximeters could be used to detect breathing problems sooner in Covid patients, so they get treatment earlier, thereby reducing the risk of developing more severe symptoms.

He explains that by the time patients actually notice they're having trouble breathing, they often require ventilation. So are these cheap devices the magic bullet for treating coronavirus? In the meantime, to learn what pulse oximeters do, what their shortcomings are, and how to interpret the data they record, read on.

After this, you will find a selection of pulse oximeters that you can buy today. Once the preserve of medical settings, they are increasingly found in fitness trackers and even smartphones, letting you check your sats quickly and easily, wherever you might be. Low blood sats can be associated with a number of medical conditions including anaemia, sleep apnoea, COPD and pneumonia. To name a few pitfalls, cold fingers, low blood pressure and ambient light can all result in inaccurate readings.

Lipnick, M. Garmin recommends that, to get the best readings, you should make sure the device is snug on your wrist and that you keep it still at the same height as your heart.

For smartphones, the evidence is even more damning. Indeed, a study from April concludes that "it is not physically possible to measure SpO2 using current smartphone technology. As Levitan argues in his New York Times piece, anyone using a pulse oximeter should consult their doctor first.

If you have a high temperature or a new continuous cough, you should call the coronavirus service, where you will be asked about your symptoms and told what to do. You should not visit your GP, pharmacy or hospital until you have done so.

At the time of writing, this pulse oximeter is only available at select Argos stores for collection.

Worn on the finger, it promises readings in a matter of seconds and its lanyard means you can always keep it nearby. Buy now from Argos. It offers clinically tested accuracy and also tracks pulse strength in addition to pulse and SpO2 data. Buy now from Lloyds Pharmacy. Instead, they take measurements while you sleep, and measure SpO2 variability instead of giving you a percentage rating.

To check your SpO2, swipe to the appropriate screen, tap it and the tracker will start measuring your blood oxygen levels. Read our full review of the Honor Band 5 here. To check your SpO2 levels, tap the menu button, swipe to the icon with a heart and tap it. After this, tap the Pulse Ox symbol and the tracker asks you to keep still while it takes a reading.And while it would certainly be handy right now to have easy access to that figure—the same one you get when your doctor sticks your finger in that little clamp during a checkup—I have the sad duty to report that whatever number your smartphone is delivering you is likely not accurate.

According to a recent post from its Centre for Evidence-Based Medicine :. Furthermore, the scientific basis of such technologies is questionable. Oxygen saturation levels obtained from such technologies should not be trusted. What about other devices that can allegedly measure your blood-oxygen levels?

With regard to accuracy, Fitbit has developed products and services to track certain wellness information as accurately as reasonably possible. Knowing your blood-oxygen levels can help you better understand whether the symptoms you are experiencing are likely to be indicative of a COVID infection.

I say even that much with hesitation, as your blood-oxygen level just one data point—and not even the most important one, as Dr. As we wrote:. For example, a bit of nail polish on your fingernail can result in an artificially low number. Worse, using that number as the basis for an at-home diagnosis of COVID is probably going to do more harm to your mental health than good to your physical health.

If you feel you truly need one of these devices to measure your blood-oxygen levels on a regular basis, run it by your doctor.

High blood pressure, or hypertensionis linked to increased risk of heart disease, stroke, kidney disease, and other conditions. Unfortunately, not only do many people have high blood pressure without knowing it, accurately measuring blood pressure is tricky because it changes so much at different times of day and in response to different emotional and physical events.

It could also allow researchers to better study the relationship between blood pressure and health.

Samsung’s Galaxy Watch is supposed to measure blood pressure — but how accurate will it be?

Whether the Samsung watch can do this is still an open question. The company has been short on details, but it appears that the watch will use an optical sensor to read blood pressure using a technique called photoplethysmography PPGaccording to Wendy Mendesa psychophysiologist at the University of California San Francisco who helped Samsung develop the tool.

The feature has actually been around for a year on the Samsung Galaxy S9. The Galaxy S9 phone has an optical sensor that shines light onto tissue in this case, the fingertips and then detects how much light bounces back. On its own, PPG can technically only measure changes in blood pressure.

During a traditional blood pressure reading, a doctor puts a tight inflatable bladder, or cuff, around the arm to block the flow of blood. As the cuff releases, the doctor measures the points at which blood starts flowing again. This is the most common way of measuring blood pressure without actually sticking a needle in the artery, and is more clinically accepted than a technique like PPG.

For its part, Samsung has released very few details, and did not respond to CNBC inquiries about whether the device integrates with third-party wireless cuffs, how often it needs to be calibrated, or how it validated the data. In a statement to The Verge, Samsung said that it will share details at a later date. Mendes said that her group is working on writing up data from the validation study, which involved subjects and compared the app against three different, medical-grade sources of blood pressure.

Another smartwatch, created by Omron, uses the cuff method to measure blood pressure and was approved by the US Food and Drug Administration in December.

There is no word, however, on whether Samsung also plans to apply for or receive clearance from the FDA. This split between wellness and medical products is frustrating to cardiologists like Bruce Alpert, who sits on the International Organization for Standardization committee for blood pressure monitors.

That concerns doctors. And relying on apps could be dangerous, says Walter Schrading, director of the office of wilderness medicine at the University of Alabama at Birmingham School of Medicine. Their findings were consistent with other studies, which also found that pulse oximetry apps were inaccurate. A recent analysis from the Centre for Evidence-Based Medicine at the University of Oxford, which reviewed the research on apps in the context of the COVID pandemic, also concluded that they are unreliable.

A: No. The device calculates the difference to determine how much oxygen is circulating. Samsung phones have a red light function, the Centre for Evidence-Based Medicine said, but they only use one wavelength and would likely be unreliable as well. In addition, standard pulse oximetry devices send light wavelengths through the finger and read the results from a sensor on the other side. Smartphones send and capture the light from the same spot — they rely on the reflection of the wavelengths.

That method tends to be less accurate and can be skewed by light from the environment. Some models of Fitbit and Garmin smartwatches also have pulse oximetry features. Fitbit can track oxygen level trends during sleepand Garmin can give on-the-spot readings. Their watches do use red light, but they use the less-accurate reflective method.

Both companies note on their websites that their devices should not be used for medical purposes. Usually, someone with a low blood oxygen level knows it — they struggle to catch their breath.
