Who Needs to Monitor Oxygen Levels at Home in Daily Life

Who Needs to Monitor Oxygen Levels at Home in Daily Life


Normally, oxygen saturation (SpO2) means how much oxygen the hemoglobin in your blood is carrying.

Normal blood oxygen saturation in a healthy person is approximately 95-100%. If oxygen levels fall below this level, lung disease may be present. A level below 92% (in the case of chronic obstructive pulmonary disease — COPD, 88%) indicates a serious condition that may require supplemental oxygen or hospital monitoring.

The higher the oxygen saturation in the blood, the better the metabolism of the body. However, it does not mean that the higher is better. Too high will cause cell aging; too low will cause insufficient oxygen supply to the body, accompanied by dizziness, sleepiness, irritability, and other symptoms.

So who will need to monitor this indicator in daily life? Should you really monitor your blood oxygen levels at home? Wellue teams have made the following summary.

1. Patients with COVID-19 including those who have confirmed or suspected COVID-19

A drop in blood oxygen saturation is one of several typical symptoms of coronavirus and a valid indication to distinguish coronavirus from the common cold. Patients with lung infections tend to have decreased blood oxygen saturation, and this also applies to COVID-19. The epidemic is still spreading but the medical system’s support has collapsed, leaving many patients in home isolation. Controlling the infection is a key to prevention and control this epidemic. The epidemic should continue to exist this year, while local outbreaks are likely to occur. Then once you find your blood oxygen saturation suddenly low in daily life, you need to pay enough attention and seek timely medical attention.

Wellue hands over its remote solution. Its Oxylink Remote Oxygen Monitor proves its value in telemedicine.

Oxylink™ Remote can track a wearer’s SpO2 and HR, and stream the vital signs data to his/her family members or doctors via Remote Linker, creating a reliable telemetry system.

2. Patients with chronic diseases such as diabetes, heart disease, respiratory disease, sleep apnea etc.

Patients with chronic diseases such as diabetes, heart disease and respiratory diseases, especially the elderly, are characterized by low cure rates, high incidence of complications, and high death rates. They may require long-term care and need to keep good habits to slow down the development and deterioration of the disease. Thus daily monitoring of physical signs and symptoms is particularly important.

In addition to some common self-monitoring indicators such as heart rate, blood pressure and body temperature, with more and more smart wearable devices adding the function of blood oxygen monitoring, blood oxygen monitoring has also become popular. And for patients with chronic diseases, the continuous monitoring of this indicator has become easier. Just using a pulse oximeter to take an instant check is not so helpful. Wellue creates its oxygen monitors for long-term tracking of your SpO2 and pulse rate, such as O2Ring continuous oxygen monitor, Checkme O2 Max Wrist oxygen monitor. By recording these indicators continuously, not only can you better manage your health data outside of the hospital, but you can also go to the hospital for timely follow-up examinations based on the deterioration of the indicators. At the same time, the trend changes of these data are also very important for doctors to diagnose and adjust the treatment plan.

With extra-long battery run-time of 72 hours (more than 7 full nights) per charge, Checkme™ O2 Max Wrist Oxygen Monitor may well be the ultimate solution for continuous O2 saturation monitoring during sleep. Moreover, it has alarm reminders including audio notifications on the free APP and silent vibration on the device, which means you will get an alert if the too low oxygen level is detected.

3. Exercise enthusiasts

Like chronic disease patients, it is also very necessary to monitor exercisers’ vital signs to adjust the intensity and frequency of exercise. Especially when doing high-intensity exercise, they are easy to have an insufficient oxygen supply. In serious cases, acute ischemia, cardiac arrest, and interruption of cerebral blood flow may be led, which can cause sudden cardiac death and sudden death, as evidenced by the fact that there have been a number of reports of sudden death in sports this year. So it is very important to reasonably grasp the intensity of exercise.

How to Choose the Right Oxygen Monitor for Home Use?

How to Choose the Right Oxygen Monitor for Home Use?

how to choose the right oxygen monitor for home use
A pulse oximeter is commonly known as a device that can measure SpO2 (oxygen saturation of hemoglobin in a patient’s arterial blood) in a non-invasive way. Now the technological advancements have made it possible to either provide continuous monitoring or spot-checking.

Real-time monitoring of blood oxygen levels now allows clinicians and patients to actually diagnose illnesses such as hypoxemia and sleep apnea at an early stage. Thus continuous monitoring of blood oxygen saturation has become vital in personal health management as it presents an indication of whether the lungs are functioning properly.

People who want to monitor their oxygen levels at home may wonder know how to choose the right oxygen monitor. Here are some tips collected by Wellue.

How to Choose the Right Pulse Oximeter

When you are going to choose the suitable home-use continuous oxygen monitor, better to refer to choosing tips as following.

1. Certification check & Review reference

Before paying for your order, you have to remember that accuracy is the most important factor to decide whether to buy medical equipment. The best way to make sure of the accuracy before you actually use the monitor is to check for the certifications and refer to the customer reviews. Someone who has bought and used the product will have their sounds online to phrase or make complaints, which sometimes can help you judge the quality.

Some reliable certifications are provided by a few organizations, such as the FDA and CE. Those organizations will review the quality and standards to assure the accuracy of the medical device.

2. Oxygen monitor type selection

In terms of design, if you do not consider other factors, just choose your favorite type, ring, or wrist, whatever is okay. But if you want to monitor the SpO2 for the whole night, we will strongly recommend you to choose the continuous overnight oxygen monitor rather than the fingertip pulse oximeter. As you know, the fingertip pulse oximeter uses the spot-checking approaches. If you do not have the need to monitor the oxygen saturation for several hours, the cheap fingertip pulse oximeter is more suitable.

3. Price & Features comparison

The price of oxygen monitors ranges from 10USD to 200USD. The general fingertip pulse oximeter is much cheaper and you can find one in pharmacies or online stores. As for the continuous overnight oxygen monitor, the price is slightly higher, as its function is improved well.

In terms of features, you can make your decision about what you need. Some have a bright and clear display; some are water-resistant; some can achieve remote monitoring. Also remember to consider if it is light to carry, comfortable to wear, easy to use, durable and portable.

Some Benefits of Wellue Continuous Overnight Blood Oxygen Saturation Monitor

Continuous oxygen monitoring is a better way to prescribe long-term oxygen therapy.

First, it can monitor one’s oxygen saturation over time, providing more utility for trends over time instead of absolute thresholds.

Second, if your oxygen levels are dangerously low or your abnormal heart rates are detected, it can alert with vibration or audio alarm on the free APP ViHealth, such as O2Ring continuous oxygen monitor and SleepU oxygen monitor, which is particularly helpful for patients with obstructive sleep apnea.

Third, using this product to monitor the blood oxygen saturation actually could offer peace of mind to people with obstructive sleep apnea, chronic respiratory or cardiovascular conditions, or people under anesthesia.

Fourth, it can also help assess the need for supplemental oxygen. For instance, when this is done overnight, a continuous measurement can be graphed and stored on your phone. The graph helps the doctor see if you have enough oxygen in your body when you sleep and ensure the amount of supplemental oxygen.

Fifth, the continuously monitored blood oxygen saturation level will indicate dangerous side effects in people taking drugs that affect breathing or oxygen saturation.

I use it every single nap time and every single night now! If he is any bit stuffy during the day we have playtime with the monitor on and we absolutely love our Wellue baby monitor! A few nights before I got my device in the mail, we had a scare where he stopped breathing again on us and now I have so much reassurance every day, and when he’s sick or having a bad day with asthma! I can have a device to alert me like I have someone helping me watch him when I ain’t able to look, I have two kids so I can’t have my eyes on him every second! I truly recommend this device to any mother, because no one knows what your baby will go through and start facing in life! There are so many sicknesses and so many babies dying that something like this is such an amazing thing to have!












Dealing with Covid but WE HAVE OUR MONITOR NOW!!!!!! Thank God!!!! 

My experience: I received it and the first thing I noticed is it’s very well made, it made me feel like hospital quality equipment. I got it out of the box and put it together it was very simple to figure out and there is an app on your phone you can get and use without even having to use the Internet turned on. I’ve used a couple of devices that I borrowed from friends and so far this is my absolute favorite. This has done better than the owlet when it comes to reading oxygen and it’s something you can buy and not expect to have to buy 10 other things for it! It doesn’t need wifi, it stores your data, it’s so on point with everything, it really feels like my baby is hooked up to a hospital monitor (I showed it to my friend that works in ICU and she said it’s literally just like a hospital-grade device).

And it has alerts that go off if there is any worry with anything. And the best thing about it all is you can use this device all the way up to 3 to 4 years old and that’s pretty amazing because you can really get your money’s worth out of it! I feel like I have already got my money’s worth out of it on the first week and that’s just because it works that great!!! I know I’m gonna be using this thing for many years and I have no reason to keep searching for another device because this one does everything I was looking for it to do!



Such a relief to be able to check this any time and such great quality

Sleep Apnea Treatments Reduce Stroke Risk

Sleep Apnea Treatments Reduce Stroke Risk

Sleep apnea is a condition marked by abnormal breathing during sleep. People with sleep apnea have multiple extended pauses in breath when they sleep.  There are three types1 of sleep apnea, including obstructive sleep apnea(OSA), central sleep apnea(CSA), mixed sleep apnea. OSA is much more common than CSA. Obstructive sleep apnea is estimated to affect between 2-9% of adults(1) in the United States.

Obstructive sleep apnea is associated with multiple major stroke risk factors such as high blood pressure, atrial fibrillation, diabetes. It is also an independent risk factor for stroke. Luckily, treatments for obstructive sleep apnea are available. Treating sleep apnea earlier can lead to greatly reduced risks of stroke as well as improvements in the quality of life and overall health and well-being.

Prevent High Blood Pressure

Several studies have established OSA as a strong risk factor for high blood pressure(hypertension), one of the leading risk factors for stroke(2).Sudden drops in blood oxygen levels that occur during sleep apnea increase blood pressure and strain the cardiovascular system. Having obstructive sleep apnea increases your risk of high blood pressure.

High blood pressure damages arteries throughout the body, creating conditions where they can burst or clog more easily. Weakened arteries in the brain, resulting from high blood pressure, put you at a much higher risk for stroke. Preventing or controlling high blood pressure can greatly lower the chances of having a stroke.

For those who have been diagnosed with sleep apnea, it’s very important to accept sleep apnea treatment and have the blood pressure measured regularly

Prevent Atrial Fibrillation

Obstructive sleep apnea(OSA) is common among patients with atrial fibrillation(AF). Growing evidence suggests(3) that OSA is associated with the initiation and maintenance of AF. This association is independent of obesity, body mass index and hypertension. OSA not only promotes initiation of AF but also has a significant negative impact on the treatment of AF. Patients with untreated OSA have a higher AF recurrence rate with drug therapy, electrical cardioversion and catheter ablation. Treatment with continuous positive airway pressure(CPAP) has been shown to improve AF control in patients with OSA.

Atrial fibrillation(AF) increase the risk of stroke by 5-fold, and more than 40% of all strokes in patients older than 80 years are attributable to AF(4).In AF, the chaotic rhythm may cause blood to pool in the heart’s upper chambers(atria) and form clots. If a blood clot forms, it could dislodge from the heart and travel the brain. There it might block blood flow, causing a stroke.

Preventing or controlling atrial fibrillation can greatly lower the chances of having a stroke.

Tests used to diagnose atrial fibrillation include:


Holter monitor

Stress test


Transesophageal echocardiogram

Chest X-ray

How Wellue Can Help

Wellue holder monitor: This portable monitor tracks the heart’s electrical activity over 24 hours. It’s useful because atrial fibrillation events may not happen all the time. The data can be easily shared with the doctors.

Prevent Diabetes

Studies suggest(5) (6)that obstructive sleep apnea is independently associated with alterations in glucose metabolism and places patients at an increased risk of developing insulin resistance and diabetes. The oxygen desaturation index is the main determining factor(7).

Diabetes is a well-established risk factor for stroke(8). Diabetes means you have too much sugar(glucose) in your blood, and this can make you more likely to have a stroke. This is because having too much sugar in your blood damages the blood vessels. It can make the blood vessels become stiff, and can also cause a build-up of fatty deposits. Preventing and controlling diabetes well can reduce stroke risk.

How Wellue Can Help

For those who have been diagnosed with diabetes,self-testing the blood sugar (blood glucose) can be an important tool in managing the diabetes and preventing complications. Wellue Checkme Suit enables at-home blood sugar testing every day.

Be Informed, Be Healthy

People with sleep apnea can live long, healthy lives, free from heart disease, stroke, and other health problems. Recognizing the connection between sleep apnea and stroke is the first step towards lowering stroke risk. Here are more tips:

Work with your doctor to manage your sleep apnea and other stroke risk factors, such as hypertension and high cholesterol.

Limit your alcohol consumption.

If you smoke, quit.

Maintain a healthy diet.

Add regular exercise to your routine.

If you think you’re having a stroke, seek emergency help right away.

How Wellue Can Help

It’s very important to evaluate the effectiveness of sleep apnea treatments at home. When a sleep apnea event happens, the blood oxygen level(pulse oximetry reading: SpO2) drops. Overnight blood oxygen level fluctuation can be used to monitor the ongoing treatment(9).

How Pulse Oximeters relate to COVID19 and if it’s truly a must-buy

How Pulse Oximeters relate to COVID19 and if it’s truly a must-buy

The continuing battle with the global spread of the novel COVID-19 has emphasized and revitalized the vital role of innovative tools that could help detect symptoms before the clinical condition worsens. Thus, the COVID-19 pandemic has brought about an influx in demand for home monitoring tools, particularly pulse oximeters, since one of the clinical concerns with acquiring a COVID-19 infection is its respiratory effects. Respiratory function, specifically, oxygenation, can be impaired by severe COVID-19 infection. The virus damages the lung, thereby reducing oxygen intake capacity. With pulse oximetry, important data on respiratory parameters are reflected. It could monitor COVID-19 disease progression by measuring the oxygen saturation (SpO2) in a person’s blood.

How Pulse Oximeters Work: Detection of Blood Oxygen Levels

Although people infected with COVID-19 can manifest with varying symptoms, the most common initial symptoms observed in patients are fever, cough, fatigue, and myalgia. Symptoms are then classified as mild, moderate, and severe. Those with mild symptoms and are otherwise healthy are often sent home to manage their symptoms. Pulse oximeters can be useful for these patients. The home pulse oximetry readings can accurately reflect important clinical insight on respiratory deterioration. The blood oxygen level of a person infected with the novel coronavirus may be lower than average. This condition is known as hypoxia. The more severe the infection, the lower the oxygen saturation reading will be. Some patients unknowingly have decreased blood oxygen levels during the early stages of COVID-19. Their clinical status can immediately deteriorate, and they can eventually manifest with shortness of breath, which leads to higher mortality rates. Having a pulse oximeter can detect low blood oxygen levels before the onset of severe symptoms.  

A pulse oximeter like the Wellue OxySmart™ is designed as a clip that fits on a person’s fingertips or toes. The Wellue O2Ring™, on the other hand, is a ring-like device that the patient can wear. Both devices make use of light-emitting diodes (LEDs) and a light detector. When the oximeter is attached to the fingertip, the LEDs and the light detector capture blood flow from the small vessels. From this, the device can then measure the percentage of oxygen-carrying blood within seconds. The pulse oximeter also has a monitor that displays the SpO2 rate and a pulse wave, representing the pulse rate. It can be used to determine how much oxygen a patient needs and when they may need it.

Not only could pulse oximeters like Wellue OxySmart™ and O2Ring™ Continuous Ring Oximeter record SpO2, but it could also document the corresponding pulse rate, heart rate, perfusion index, and movements of a person. There is merit in knowing these health parameters, especially SpO2. The National Institutes of Health (NIH) recommends oxygen saturation levels of 92–96%. Anything below this range indicates a severe case of COVID-19 infection, which may require urgent hospitalization for immediate oxygen supplementation and critical care. It is where data collected from a Wellue OxySmart™ and O2 Ring™ Continuous Ring Oximeter can be life-saving.

The use of these devices by generally healthy people and patients diagnosed with mild COVID-19 symptoms cannot aid in establishing whether or not there is a need for them to be hospitalized. However, people can monitor their clinical status even in the comforts of their homes since these devices can instantly analyze the user’s condition.

Benefits and Pitfalls of Pulse Oximetry

Pulse oximeters are not foolproof. The method or technique of measurement can affect the oxygen saturation that will be recorded. Improper placement of these devices can inaccurately reflect oxygen levels in the blood. The best reading can be achieved with a strong pulsatile flow from the site of measurement, granted that the wearer has warm hands and is relaxed.

However, both Wellue OxySmart™ and Wellue O2 Ring™ Continuous Ring Oximeter are FDA-approved wearable electronic devices that can monitor oxygenation continuously, remotely, and noninvasively. The data is gathered in real-time. It is then seamlessly uploaded to a mobile, tablet, or computer app, which can be viewed by the wearer and conveniently shared with a health care provider. This feature will eliminate the need of the user to physically go to the hospital or clinic if it’s only for a check-up. With the data from these devices that they can easily muster, they now have the option to talk to health professionals through online consultations and still have an updated and monitored analysis of their current health condition. Doing so could mean having a smoother and easier online consultation experience. Home monitoring of blood oxygen levels can prevent premature and unnecessary visits to the emergency department and simultaneously optimize in‐person health care utilization. Especially during a pandemic, having an at-home device would be the best option to minimize the risk of getting infected.

Wellue O2 Ring™ Continuous Ring Oximeter allows wearers to capture their SpO2 levels overnight while they are sleeping. The ring vibrates to alert the wearer once their blood oxygen levels fall below the optimal range. This can be particularly helpful in monitoring oxygen saturation in COVID-19 patients while they sleep. Heart rate, respiratory rate, and overall sympathetic tone are decreased during sleep. COVID-19 patients who are already critical would not be able to tolerate a fall in sympathetic tone since this can further aggravate hypoxia. The ring oximeter readings can be used to assess oxygenation in patients under critical care. It can help detect early decompensation and subsequently allow healthcare professionals to deploy resuscitative measures.

All in all, pulse oximeter readings may not reveal the severity of the disease process, and patients should, therefore, always seek further medical evaluation if they are experiencing any COVID19 related symptoms. They should not solely rely on these devices to detect medical conditions such as COVID-19, COPD, pneumonia, asthma, and other disease entities with a failure in oxygen supply. Pulse oximeter devices are used mostly for conveniently monitoring the wearer’s current health condition. It is also a great tool to determine the consistency of their health, as well as a warning device that can help the patient be more conscious of their health insights.
