Fitbit Rolls Out Blood Oxygen Tracking With An Eye Toward Fda Clearance For Sleep Apnea Diagnosis Feature

Heather Landi

Wearables giant Fitbit has rolled out a blood oxygen monitoring feature on some of its smartwatches, beating the Apple Watch on adding this functionality.

Fitbit, which Google agreed to buy in November, confirmed to FierceHealthcare that the company has activated a feature on its Charge 3, Ionic, Versa, Versa Lite and Versa 2 devices that provides users in the U.S. with blood oxygen data via the Fitbit app.

Users can see whether they are experiencing large variations in blood oxygen levels while they sleep.

The estimated oxygen variation graph provides users with an estimate of the variability of oxygen levels in their bloodstream, also referred to as SpO2. The data are derived from a combination of the red and infrared sensors on the back of the device, according to MaryEllen Green, a spokesperson for Fitbit.

The data shown in the graph are not a relative Sp02 estimate. “Being aware of variations in the oxygen levels in your bloodstream may indicate variations in your breathing during sleep. In general, variations should be low,” Green said.

Apple holds patents for blood oxygen monitoring but has yet to activate the feature in any of its devices, according to CNET. Back in 2018, Garmin introduced Pulse Ox with its Vivosmart 4 activity tracker, allowing users to gauge their blood oxygen saturation levels on the spot or periodically as they sleep, CNET reported. 

How To Increase The Oxygen Levels In The Body What Is Proning And How Is It Useful

If the oxygen saturation level of the blood drops below ninety-four percent, you can practice proning at home, too, especially if the hospitals near your location have a shortage of beds and space. Proning is a procedure where the patient is made to lie with their face down, that is, on their abdomen. When resting in this position, the oxygenation in the patient improves as the alveolar units remain open. This can be performed up to ten times during the day.

In January 2020 Fitbit turned on its long awaited blood oxygen detection feature. Since 2017 it’s been packing an SpO2 sensor into its leading devices, but hasn’t used the data. Until now.

Blood oxygen can be used to detect sleep conditions such as sleep apnea, and offer a better analysis of what’s going on with our bodies in those lost hours.

But Fitbit’s Estimated Oxygen Variation data needs a little explanation. We spoke to Dr. Conor Heneghan, Fitbit’s Lead Sleep Research Scientist for everything you need to know.

Q: Whats A Normal Blood Oxygen Level And When Should I Be Concerned

Dr. Pristas: If you’re using a pulse oximeter to measure your blood oxygen level, a normal reading is a Sp02 level that’s between 95 and 100 percent. However, this may vary for people with certain medical conditions, such as lung disease. Speak with your doctor to determine what ‘normal’ is for you and keep in mind that while these at home devises are handy and non-invasive, they are not always 100% accurate. In fact, Apple says its new blood oxygen feature should only be used for general fitness and wellness purposes and should not be used to diagnose, monitor or treat any medical conditions. Other tests, performed by health care providers, include blood draws or breathing tests to accurately measure blood oxygen levels. If your Sp02 is below 95% you should consult with your health care provider.

What You Need To Know About Sleeping With An Oxygen Concentrator

I want a quote for oxygen

Any professional oxygen company can tell you that you breathe differently when you are asleep compared to the norm. Some people take shallow, erratic breaths, others breathe through their mouths. At any rate, the oxygen level in the blood drops down during sleep, and this is normal up to a level.

However, if you suffer from various medical conditions, such as asthma, sleep apnea, obesity or heart diseases, you may not get enough oxygen during sleep. And low oxygen levels lead to complications of your pre-existing conditions, as well as the occurrence of new health issues, such as:

  • Sleep disorders, including insomnia
  • Type 2 diabetes
  • Potential brain damage due to depressed brain function.

In the worst-case scenarios, low oxygen levels can lead to loss of consciousness, coma, or sudden death.

Recording Your Results In Your Diary And Acting On The Results

Your first measurement is your baseline – your doctor will record this in the highlighted blue area. Then you take recordings three times a day, at the same time each day – for example in the morning, at midday and in the evening. Take extra measurements if you feel there has been a change in your health. Please also record changes in how you are feeling and your breathing.

Keep track of your temperature if you can. However, as long as your oxygen level and breathing are normal, you do not need to contact the BREATHE service or NHS 111 if you have a temperature or other symptoms, such as cough, muscle aches, tiredness and change in taste or smell. Paracetamol and regular fluids can help with these symptoms, and most people will get better by themselves within two to three weeks.

Please see the NHS website for information on self-isolation or how to access care.

At Which Stage Is Oxygen Therapy Most Likely To Be Necessary

Typically, oxygen becomes more necessary as COPD progresses. As the disease advances, the patient’s lung damage compounds and symptoms become more serious. Shortness of breath will become more frequent and more severe as patients progress through the COPD stages. As shortness of breath gets worse, lowblood oxygen levels become a more significant risk, which is when oxygen therapy is most beneficial. A lack of sufficient oxygen can result inhypoxia and hypoxemia—low oxygen levels in the tissue and in the blood—which can have a number of dangerous symptoms and can become a life-threatening situation if allowed to continue untreated. Treating hypoxia and hypoxemia with oxygen therapy can help raise blood oxygen levels back to healthy levels.

Who Should Be Most Concerned About Their Blood Oxygen Levels

People who suffer from a lung condition, such as COPD may need to monitor their SpO2 levels more often as they may have a lower blood oxygen level than a healthier person.  Monitoring levels can detect any problems.

People suffering from respiratory conditions such as Asthma, or Cardiovascular conditions may also benefit from more regular monitoring of their blood oxygen levels for the same reasons.

If you are thought to be suffering from an infection or virus such as pneumonia or the most recent Coronavirus outbreak, you will have your blood oxygen levels tested and monitored.  This is to determine the severity of the infection, and to monitor your oxygen levels if you may need or are receiving treatment.  See more about what happens when you are tested for Coronavirus in this video.

    How Are Blood Oxygen Levels Checked Using A Pulse Oximeter

    OOXYL™ Smart Watch Heart Rate, Blood Pressure, Oxygen ...

    A pulse oximeter is a small, mobile, and handy medical device. It is most commonly used when doctors want to know your blood oxygen levels quickly. It is also used to monitor the response of your body to certain medications or supplemental oxygen. Blood oxygen levels are indicated as SpO2, which is the percent saturation of oxygen in the blood.

    The test that measures blood oxygen levels using a pulse oximeter is known as pulse oximetry. The procedure is very simple and requires only clipping the pulse oximeter in between any of the fingers for a few seconds. The reading appears on the pulse oximeter screen. This test may be slightly less accurate than ABG but is easier to perform than ABG tests when needed quickly.

    • The brain gets affected when the SpO2 level falls below 80-85%.
    • Cyanosis develops when the SpO2 level drops below 67%.
    • The normal oxygen levels in a pulse oximeter usually range from 95% to 100%.  Note: Normal levels may vary if you have lung disorders. Your doctor can tell what levels are normal for you.

    Low Oxygen Levels: How Low Is Too Low And Should You Worry

    Low oxygen levels will rob you of your eye sight, short term memory, and your energy. Eventually low oxygen levels will weaken your heart muscle.

    How To Use An Oximeter To Track Your Sleep Apnea Treatment

    If you have sleep apnea, a portable pulse oximeter can be very useful in monitoring your blood oxygen level during sleep.

    In fact, the sleep apnea oximeter will show you how efficient is your apnea treatment.

    If your oxygen levels are below 92%, then your treatment is not effective enough1. You should maintain O2 levels above 98% when sleeping2.

    Are you wondering if your sleep apnea is under control? Do you want to know if you have healthy oxygen levels during sleep? In this page, you’ll learn how to monitor your sleep with a cheap but effective portable pulse oximeter.

    Is There Anything Else I Need To Know About Pulse Oximetry

    Pulse oximetry results may be 2 to 4 percent higher or lower than your actual blood oxygen level. For a more accurate result, your provider may do a blood test called an arterial blood gas.

    But this test can be painful. It also cannot be used at home or for continuous monitoring. You may need both types of tests to manage your condition.

    Q: Why Is There Increased Interest In Blood Oxygen Levels

    Dr. Pristas: People started to buy pulse oximeters to measure blood oxygen levels at home when they learned that low levels could be a sign of COVID-19. Shortness of breath is a well-known symptom of COVID-19, but it’s not always easy to detect. Some thought this device could be a tool to help self-assess for signs and symptoms. There have also been reports of “silent hypoxia” where peoples’ oxygen levels are dangerously low, but they don’t necessarily experience shortness of breath.

    This page and diary is your online version of the paper guide your doctor has given you along with a pulse oximeter because you have symptoms of COVID-19.

    It explains why it will help you and your doctor monitor and manage your health better.

    A pulse oximeter is a small device which helps you to monitor how fast your heart is beating and the level of oxygen in your blood. It fits on to your finger.

    Blood oxygen level is the most accurate way of keeping an eye on your progress with COVID-19.

    An ideal oxygen level is between 95% and 99%. An ideal heart rate is between 50 and 90 beats per minute .

    The oxygen level may be lower in some people with lung conditions, even when they are well. If you have an existing lung condition, your doctor will let you know what the levels mean for you

    When Do Pulmonologists Decide To Prescribe Oxygen Therapy

     Pulmonologists typically prescribe oxygen therapy to patients who are unable to treat breathlessness with other COPD treatments likepulmonary rehabilitation,breathing exercises andmedications. Once a patient’s COPD has progressed to the point that they begin to show continued shortness of breath even with other regular therapies, pulmonologists are likely to prescribe oxygen therapy to COPD patients who:

    • Have an oxygen saturation of 92% or below while breathing air
    • Experience severe airflow obstruction
    • Have swelling in their lower legs caused by low blood oxygen
    • Have an increased concentration of hemoglobin in their blood

    Be aware thatdoctors are careful to reserve long-term oxygen therapy for patients who truly need it, because once a patient begins long-term oxygen therapy, they are likely to need it for the rest of their life. Typically, long-term oxygen therapy is given to patients for a minimum of 15 hours per day. Patients may use oxygen therapy overnight if they tend to experience worsening hypoxemia while sleeping. The benefits of long-term oxygen therapy, when used at least 15 hours per day in COPD patients with severe and chronic hypoxemia, has beenwell documented and it has been shown to increase survival for those patients. Your pulmonologist will carefully explore your pattern of low blood oxygen to determine the right oxygen prescription for you.

    Increase Oxygen Levels While Sleeping: 12 Tips To Follow


    Oxygen is necessary for several vital functions within the body. In fact, without oxygen we die. But even low oxygen levels—hypoxia or hypoxemia—can cause problems, while high levels can improve our health.

    Getting enough oxygen during sleep can be particularly difficult as our breathing patterns change while we are sleeping and we aren’t conscious of it. We may also sleep in positions that compress the lungs, have breathing problems that don’t present during the day, or suffer from underlying medical conditions.

    Thankfully, there are ways and means to increase our oxygen levels while sleeping. And even if you don’t currently suffer from low oxygen levels, there’s something to be said for prevention. For example, sleep apnea and snoring, which are common causes for low oxygen levels during sleep, can often be prevented.


    Read on to find plenty of helpful tips for increasing your oxygen levels during sleep, as well as to find out more about the causes and symptoms of low oxygen levels.

    What Can You Do To Improve Blood Oxygen Levels Naturally


    You will be happy to know that there are many things that can make your lungs healthier and therefore improve blood oxygen levels.

    Eat well including foods that contain vitamin D and iron, exercise, do breathing exercises, sing , get fresh air , sleep on your side, deal with potential sinus problems, avoid alcohol four hours prior to bedtime , get enough sleep, quit smoking and stay hydrated.

    If you can’t naturally improve your blood oxygen levels, get medical help.

    Causes For Low Oxygen Levels Frequently Asked Questions

    How Do You Measure Oxygen Blood Levels?

    You measure it through an arterial blood gas test, or a pulse oximeter. The latter is easier , but the former is slightly more accurate.


    While you will want to get a doctor to perform an ABG test if you’re worried about your blood oxygen levels, you can use a pulse oximeter at home to check them at any time. It can be a great way to find out if you have low blood oxygen levels while sleeping—set your alarm at different hours of the night to wake up and check.

    What Are Normal Blood Oxygen Levels?

    A blood oxygen level of between 75 and 100 millimeters of mercury , is considered to be OK. Anything below 60 mm Hg is considered abnormal and the medical professional that carried out the test will likely prescribe some form of treatment plan.

    If you use a pulse oximeter you measure the oxygen saturation percentage. You have good blood oxygen levels if it measures 95-100%, while below 90% is considered abnormal and you should contact your doctor immediately.


    When we sleep our blood oxygen levels go down as we breathe more slowly and some alveoli in our lungs are not used. Therefore, don’t be alarmed if you are using a pulse oximeter and it registers below 95% during the night. Still, if it drops below 90% you should see your doctor for advice.

    Signs That You Dont Get Sufficient Oxygen While Sleeping

    The question is: how do you know that you do not get enough oxygen during sleep? Most people are not aware of what they are doing during sleep. However, there are many signs you can identify yourself or find out from others, indicating poor levels of oxygen during sleep. 

    Some of these signs are:

    • You wake up choking or gasping for air
    • You feel dizzy, drowsy, and fatigued during the day
    • You experience shortness of breath
    • You have moments of confusion and disorientation
    • You feel anxious or depressed for no reason
    • You have trouble recollecting events and experience memory loss.

    Also, if your significant other complains of your loud snoring and restlessness during sleep, these are other telltale signs of low oxygen during sleep.

    How To Tell If Youre Not Getting Enough Oxygen At Night:

    There are a few signs to watch out for to see if you’re not getting enough oxygen while you’re sleeping. If you are experiencing any of these signs by themselves or in combination, don’t ignore them. Not getting enough oxygen while you sleep for any length of time is dangerous.

    You get plenty of sleep at night, the eight hours or so that you need each night , but you still feel exhausted in the morning or throughout the day. Having a lack of oxygen in your bloodstream puts a strain on your heart and your brain, and the rest of your body has to work harder to make up for the lack of oxygen.

    Aside from feeling more tired during the day, you will notice you can’t think as clearly. Simple tasks can seem extremely hard and complicated to someone whose brain isn’t receiving adequate oxygen. You can also experience regular headaches and become very irritable and moody for any small reason. You would also experience memory loss and the ability to concentrate that could be mistaken for the onset of Alzheimer’s.

    The Complete List Of Benefits To Sleeping With Oxygen

      According to the Journal of Respiratory Care, due to the effects of sleep on your breathing, it’s normal for oxygen levels to decrease below normal awake levels when you sleep at night. While you’re sleeping, you’re not breathing as deeply, and the lung spaces aren’t all functioning at full capacity.

      If your oxygen levels drop too low regularly, it puts you at risk for serious health problems or even sudden death, which is why it’s essential to learn more about the benefits of sleeping with oxygen and how to know when an oxygen mask for sleeping is the right option for your needs.

      Sleep Apnea Diagnosis And Oxygen Desaturation Effects

      Patients who develop sleep disturbances often seek the aid of a physician who commonly refers them for sleep studies. Sleep studies can yield important diagnostic information about a person’s sleep cycles, oxygen levels, and the quantity and length of breathing interruptions.

      What is the relationship between obstructive sleep apnea and lower oxygen levels during sleep? How does sleep apnea lead to oxygen desaturations that may affect overall health?
