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.
Yes, the risk of cardiovascular diseases will rise in Fall and Winter.
As the weather gets colder in Fall and Winter, the stimulation of cold often causes blood vessels to constrict and heartbeat to speed up, making it easier for heart attacks, heart failure and other heart diseases to occur.
Attention: In addition to keeping warm and adjusting medication to keep blood pressure stable, you must pay attention to the following heart disease warning signs.
1. Chest pain
Chest pain is the most common symptom of a heart attack, typically make you feel like a stone pressing against the chest. Moreover, the pain may also appear in the left shoulder, jaw, and possibly in the stomach.
Heart attack is a disease that can kill you at any time! If you experience chest pain, go to the hospital promptly so that your doctor can determine if it is a heart attack.
If you go to the hospital because of stomach pain or shoulder pain, your doctor recommends checking the EKG (electrocardiogram).
Of course you can test EKG in you home by yourself with a portable EKG monitor (click here to know more, see pics as following).
Palpitations are a common symptom of cardiac arrhythmia. Some people may feel that their heart has missed a beat, while others may suddenly feel a series of rapid, irregular heartbeats.
If you feel palpitations occasionally, it is usually not a big problem, mostly related to exertion and mental state; but if palpitations occur frequently, it may be a manifestation of disease, like some arrhythmias, hyperthyroidism, etc.
In the absence of hunger, exertion, etc., the presence of palpitations, along with dizziness, is likely to be signs of the more dangerous ventricular arrhythmia, which should not be taken lightly but to be treated immediately in the hospital.
3. Syncope (Fainting)
Syncope is a sudden, transient loss of consciousness that can recover on its own. The occurrence of syncope means that there is a transient abnormality in the blood supply to the brain.
Among patients with hypertension, this condition is likely to be a transient ischemic attack, implying an increased risk of stroke. And measures of prevention must be actively taken to minimize the risk of stroke.
Patients with hypertension who often feel tired and fatigued for no apparent reason may have an abnormally functioning heart. It is recommended that heart health lab tests be performed as soon as possible.
5. Breathing difficulties
Whether it is heart disease, or lung disease, it can cause shortness of breath and dyspnea.
For patients with hypertension, it is more important to be alert to shortness of breath and dyspnea that occurs at night, especially if you are woken up in your sleep and must sit up to breathe normally, which is likely to be a sign of heart failure. Once it occurs, go to the hospital in time to check the heart function and adjust the medication to avoid deterioration of the condition.
How to take care of your heart?
In addition to paying attention to the symptoms mentioned above, it is even more important to take care of your heart in general.
Control blood pressure and blood sugar well.
Refuse to smoke or to breathe second-hand smoke.
Develop a good habit of regular exercise.
Keep adopting a healthy diet.
Have regular medical checkups to know your heart health.
Monitor your heart every day with a 24-hour holter monitor. Know and record your heart condition analyzed by Wellue AI algorithm. Share your AI ECG report with your family doctor.
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 discovered that something was wrong with my baby two months after he was born: a baby should be able to eat and sleep, but my baby’s sleep time is only eleven or twelve hours per day in bits and pieces; he cries while taking milk; I feel that he wants to suck the breast, but when he eats milk, but he cries as soon as he takes milk, the kind of heart-piercing!
At first, I thought it was normal for children to make trouble. If he has any needs, he must express it by crying. Later, I found that something was getting worse by checking on the Internet and consulting a mothers’ group. When he cried, his head and neck were leaned back hard, his chest and abdomen were straightened up, and his body looked tough and uncomfortable in the bath.
My family thought he was suffering from indigestion, and found a doctor in a small clinic to prescribe a small medicine, but it didn’t work after he took it. I accidentally saw on the Internet that this may be the manifestation of hypoxia and high muscle tension, and there were various descriptions of cerebral palsy, which finally made me unable to stand. My whole family took my baby to the local children’s hospital for examination, and I registered a number of the neurology department. After examination, the doctor said that there was nothing wrong with him on the surface, except to strengthen nutrition and so on. Later, my father registered a number of the neonatology department and went to see a doctor. The doctor put the baby on the bed and tried to pull him to sit. It turned out that the baby’s head was hanging back badly, almost sticking to his back. The doctor immediately said: there is something wrong with the baby! ! ! As soon as he spoke this sentence, I almost foresaw my unhappy life with my child! I felt that my life was going to be destroyed, and my child was hopeless, because my ignorance and stupidity had harmed this child’s whole life! This was all my thoughts at that time!
My dad was there and asked him why. The doctor asked me about my pregnancy and the birth of my child. Everything was normal during my pregnancy, but when the baby was born, it was really thrilling. It was too difficult for me to give birth, the umbilical cord wound around the baby’s neck, and my amniotic fluid was turbid. However, the doctor still asked me to try to give birth naturally. As a result, the fetal heart rate dropped to 47 before I was sent for an emergency caesarean section. The baby was taken to the rescue without allowing me a look at it. Only after a while, we heard the crying of the child; The child was not sent to the neonatology department but followed me back to the ward directly. The doctor just told us to let him take oxygen for three days, and then he was discharged from hospital for seven days and went home.
I haven’t heard the saying that “this child lacks oxygen” throughout the process. As it’s the first child, I really didn’t understand it, and I suddenly realized it only when I went to check it! I hate myself. Now that I couldn’t give birth naturally, why should I insist! It’s all my fault!
The doctor said that you were late to treat him, and this situation should have been treated at birth, and then he gave a list of nuclear magnetic examination to check the baby’s brain first! The results showed that the baby’s brain ventricles were widened, leading to developmental delays, poor head lift for two and a half months, poor head control, high muscle tone, low response, easy irritation, not chasing objects or chasing sounds. All in all, there are all kinds of problems!
Later, we went to another hospital to check the baby, but it still reflected the problem of hypoxia, requiring the baby to do rehabilitation training. I strongly demanded that my child be given a brain nutrition injection, and I would give it a try whether it was useful or not. After that, we went through the hospitalization procedures for him and started the road of rehabilitation!
When I got home, I broke down and cried, fearing that I would disturb my baby, and even more afraid that my parents would see me like this. I covered my mouth hard and cried till I had no strength. My husband always comforted me that it wasn’t that serious. In fact, I knew that he was nervous and worried about the child as much as I was!
At that time, no one knew another thought in my heart: I wanted to jump off the 21st floor with my child. I didn’t want my child to become a child with cerebral palsy. I didn’t want him to lie in bed and never get up again. I didn’t want him to be pointed and flouted at for life! I didn’t want my parents being laughed at! But watching the child grow so cute, the little white face would still smile at me, which is really not as bad as the doctor said! How can I give up on him!
At that time, I took the child to get an injection every day to recover, and I couldn’t be happy anymore, but I had to force myself to smile in front of my parents. No one knew how anxious, painful and desperate I was! (The child’s father was on a business trip, I dared not say too much about my feelings, I was afraid that he would be distracted from his work).
Seeing that I was pulling a long face every day, the rehabilitation therapist always advised me that it was not so serious and that the child would be fine, and comforted me to be happy. I said: “I even don’t want him anymore”. Another rehabilitation therapist next to me said “since you don’t want the baby, give it to me. Isn’t this baby nice and lovely?” In this way, he received rehabilitation treatment for almost five months. At home, I pulled him up and found that his head could be lifted with his body by himself. I was so happy that the problem I was most worried about had improved. Later, his forearm also had strength to support his upper body, which made great progress!
He turned over a lot more smoothly than before. He could turn over and back, just like rolling, but he couldn’t control the strength of lying down, looking up, leaning back and looking up too much!
The rehabilitation therapist said that this had been very good, and at least the effect had been achieved, and asked me to keep on and not relax at home! When my family was free, they would also give the child a touch massage, and we would train him for a while almost every day, including passive exercise, massage and talking, so long as we would do anything good to him! About five months later, the baby’s grandfather let the child practice sitting. When it was one day away from six months, we went to give the child a reexamination. The doctor gave a ultrasonographic examination of brain and found that the baby’s ventricle was normal and no longer widened and that there was no longer anything wrong with his brain! This was even happier for me than winning 5 million! The 6-month-old baby would sit independently, and he would sit very straight without help, without falling backward or leaning forward! He was very hard and strong, wasn’t he?
The recovery continued! Later, he got better and better. He could creep forward in seven months and crawl on all fours in eight months. His advanced development also stunned his rehabilitation therapist, who told me the truth, saying that when we came, the child he took over was seriously ill, but he didn’t expect the baby’s recovery speed to be the most amazing, reaching the normal baby’s development level, even ahead! His words gave me great comfort, and I was no longer as unhappy as before, but cheered up and gave my baby the best company!
Almost nine months later, the baby could stand on his feet. I prepared a fence for him. He liked to crawl around inside, holding the fence and walking slowly. During this time, we still went to receive rehabilitation training every day. After ten and a half months, the baby could walk. When the adults hold him with one hand, he could walk around in the living room. It’s great! It is known that some normal babies may climb only after ten and a half months. For this problem baby, it is really hard to develop to this degree!
Later, the weather became colder and colder, and the rehabilitation therapist said we could go there once every two days. We followed up examinations every month, and all kinds of reflexes in his development were normal. What should have disappeared disappeared, what should have appeared also appeared, and the problem of muscle tension slowly returned to normal!
In fact, he said that we could continue to receive rehabilitation training or stop it. I wanted him to continue to receive treatment until he was one year old, and just regarded as early education. Eleven and a half months, he was completely out of the intervention of adults, could walk a few steps independently! Finally, I could show my baby in my circle of friends, and feel much better!
Before my child recovered, I disappeared from my circle of friends for a long time. No one knew what happened to me, and I didn’t want to talk about it, so few people knew that my child was sick!
Now the child is three years old, very smart, lively and lovely, and speaks clearly and fluently, just like a normal child. I want to say that I am very grateful to the child for his strong will, and he cured me! It was he who rekindled my passion for life!
I don’t explain the topic too much. I just want to share my experience. No matter what others do, you should weigh your abilities before giving birth to a baby. It is best to be able to give birth naturally and safely; if natural delivery doesn’t work, direct cesarean section is good for both yourself and your child!
Conscience advice from an ignorant first-born mother!
I didn’t expect that my casual answer would arouse so many resonances, and I really appreciate everyone’s heartfelt blessing to this baby and to our family ~ (What I wrote may only be understood by parents, there is no purpose or deception, and it is really pure sharing. )
In any case, a child’s health is the most important and happiest thing for a family. At that time, I was willing to trade everything I had for my child’s health, including my own life.
During that time, I repeatedly thought, if I was not rescued because of postpartum amniotic fluid embolism, could I get my child’s health back? I strongly wished that the child would not grow up so quickly, just keep the status quo, and not experience the fate of being looked down upon when growing up; meanwhile, I wished that he would grow up quickly and recover; as a mother, I was such a contradiction, living in remorse and pain every day…
However, the reality was always pushing me to keep moving forward, step by step; later, I devoted myself to his rehabilitation, and checked his development every month. If he failed to meet the standard, I would respond to the rehabilitation therapist in time and communicate what to do next. I’m afraid I did more homework than I prepared for the college entrance examination during that time. The rehabilitation therapist always said: “you know a lot.” I smiled bitterly and God knows how I lived every day…
I dare not share these contents until my baby is well. Some people say that I am great, but being a mother is tough. I’m not great at all but ashamed, because I almost seriously harmed my own child. I don’t deserve to be a mother.
However, I thank my child for giving me another chance to make up for him. Last night, he said before going to bed: I like my mother, I love my mother ~ This little angel really lies beside me so intact, and perhaps this is the truest and happiest thing for me in the world ~ ~ ~
Well, thanks again to those kind friends who care about us. I have carefully read every comment. I really appreciate your blessings and wish you a happy family. It’s most important for a family to be healthy and tidy, isn’t it? ! ! !
At the end, I attach two recent photos of my baby ~
He is mischievous now, and who would have thought that his life was on the line?
What are cardiac tests? Which kinds of tests currently exist and what are the differences between them?
In terms of cardiac testing, hospitals now usually use three types of tests: cardiac color doppler ultrasounds, electrocardiogram tests, and coronary angiographies. These three tests are responsible for examining the structure of the heart, understanding the rhythm of the heart, and showing the condition of the blood vessels, respectively.
If one day, you ever feel that your heart is uncomfortable and have to go to the hospital for an examination, the doctor will ask you to lie on the bed, stretch your legs, and untie your shirt. A light blue, sticky, and gelatinous liquid will be applied to your chest, and a thick-headed pillar will be pulled out.
The colloidal liquid is called a “medical ultrasonic couplant,” and the thick-headed column is an ultrasound probe. The human heart can be seen as comprising of four “rooms” (right and left atria and ventricles) separated by walls (myocardium) and doors (valves) that allow blood to pass through the rooms. There is a normal range of door size and wall thickness for all people. And if something goes wrong, it means the heart is “sick”.
Some people have defects in the “walls” of the heart as soon as they are born, which is often referred to as congenital heart disease.
For some people, long term high blood pressure causes the heart muscle to become fat and the “walls” to become thicker, which is called hypertensive heart disease.
For some people, due to infections, the “valves” are narrowed or not closed properly, which prevents the “doors” from opening and closing smoothly and affects the blood flow. That is called valvular heart disease.
The cardiac color ultrasound, also known as cardiac color Doppler, is responsible for observing these “door-wall” structures. The cardiac color Doppler ultrasound is one kind of ultrasound examination, but compared with the ordinary B-ultrasound, it is clearer and finer, and it can better avoid the interference of obesity and other conditions.
It clearly identifies structural abnormalities in the heart, such as the size of the chambers, the thickness of the interstitial wall, and the presence of valves that are not closing properly, narrowing, or prolapsing, as well as the heart’s ability to pump blood.
It is precisely because it is a type of ultrasound that cardiac ultrasound is a very safe way to examine the heart.
(Heart color Doppler ultrasound : this is what the doctor sees when you are lying on the bed, and he/she is scanning your chest with the thick-headed pillar.)
If one day you go to the hospital for a checkup and the doctor makes you lie on the bed with your legs stretched out, unbutton your shirt, and then stick a bunch of patches with random wires attached to them on your chest, it might make you feel like an internet or video game addict, who needs to be sent to an internet addiction treatment facility to receive electric shocks.
The human heart beats, and in addition to the number of beats having a normal range, the rhythm of the beat is also important.
A normal person’s heartbeat is as accurate as clockwork, and if it is occasionally fast or slow, it is an arrhythmia, which may affect the heart’s ability to supply blood. For example, the most common clinical arrhythmia, called atrial fibrillation, brings about a feeling of panic and palpitations, shortness of breath, fatigue, and even dizziness and fainting.
This is where the electrocardiogram (ECG) comes into play. It is made to understand the rhythm of the heart.
A routine electrocardiogram (ECG) is performed by placing electrode pads (which seems like an electrocution) and a hand and foot electrical lead system on the skin for a few minutes, which depicts the electrical activity of the heart on a curve. An experienced doctor can use these curves to know if the heart is beating rhythmically.
In addition to the conventional ECG, there is a “dynamic ECG” that compensates for a routine ECG by detecting the heartbeat 24 hours a day. In clinical practice, the ECG, combined with troponin and cardiac enzymes, is often used to detect myocardial infarction.
By the way, the technology used in lie detectors that we often see in movies is also used in ECGs, and by finding the slightest “unintentional twitch” in your wonderful little heart, your “inconsistencies” will be uncovered.
If one day you go to the hospital for a checkup and the doctor pushes you into a strange kind of big room, makes you lie down on a bed, has you spreading your legs, and you then feel like you are paralyzed, and you see several doctors in lab blouses, masks and hair covers, all wrapped up tightly, slowly pushing some kind of strange looking liquid towards your body,…
A coronary angiography is a relatively low-risk, relatively safe, surgery performed under local anesthesia. It is mainly used to visualize the blood vessels in the heart through X-rays, while the “contrast agent” is pushed towards the body in order to enhance the visualization.
As stated above, the human heart is like a house, and the coronary arteries are the tubes that supply water and oxygen to the house. The coronary arteries are located outside the heart and provide a steady flow of oxygen and nutrients to the heart. Diabetes, high blood pressure, dyslipidemia, smoking, etc., can cause impurities in the blood vessels to increase and the water flow to become less and less smooth.
To understand the condition of these coronary arteries, a “coronary angiogram” is used, through a contrast agent, that allows the physician to clearly visualize the thickness of the coronary arteries under X-rays to determine a subsequent treatment.
Because if these pipes are severely blocked, various clinical symptoms (with chest pain as the main syndrome) may appear, that is, “coronary heart disease”, which is why coronary angiography is the “gold standard” for the diagnosis of coronary heart disease.
Through local anesthesia, the femoral artery is punctured, the arterial sheath is implanted, the angiography catheter is sent into the left and right coronary orifices, the contrast agent is injected at multiple projection angles, and then the condition of the coronary artery is displayed on the monitor screen to determine the degree of coronary artery disease.
But don’t be afraid to look. A coronary angiography is generally used for coronary heart disease, not for ordinary cardiac examinations.
In conclusion, the three most common types of heart tests are cardiac ultrasounds, electrocardiograms (EKG), and coronary angiograms. Doctors will use one or more of these tests to help determine what is wrong with the heart by understanding its structure, rhythm, and blood vessels.
In addition, cardiac tests also include cardiac MRIs (magnetic resonance imaging), etc. As for the choice of which test to do, you should go to the hospital and listen to your doctor’s advice based on your symptoms.
