What is oxygen saturation? What kind of people should they pay attention to?

In layman's terms, blood oxygen saturation.

It is hemoglobin, which binds to oxygen in the blood.

The content of the ratio of all hemoglobin is an important parameter of whether the person's respiratory circulation is healthy, and it can be seen from the blood oxygen saturation whether a person's breathing and cardiovascular health are healthy, and it is also an important indicator to evaluate whether a person is healthy.

In general, the main clinical measurement is arterial oxygen saturation and venous oxygen saturation, so why not test oxygen saturation elsewhere? Because it is difficult for other human tissues to carry out non-invasive oxygen saturation measurement, and the measurement of arteries and veins basically satisfies the general examination, under normal circumstances, the arterial oxygen saturation of a healthy person is 98%, and the venous oxygen saturation is 75%.

Under normal circumstances, people's oxygen saturation should be above 95%, and the blood oxygen saturation of long-term smoking groups is generally lower than 95%, in medicine, it is believed that when a person's blood oxygen saturation is lower than 90%, some organs of the human body have problems, and below 80% of the case, people's lives are in danger, if less than 60%, this person is not saved.

What happens when a person's blood oxygen saturation is insufficient? Lack of energy, lethargy.

Fatigue easily and memory loss.

And so on, if a person is in a situation of insufficient blood oxygen saturation for a long time, it will cause irreversible damage to human organs, especially the brain and heart.

In fact, the human body has a very obvious feeling of the decline in blood oxygen saturation, the most common is to feel dizzy and out of breath, at this time it is necessary to pay attention, it may be caused by insufficient blood oxygen saturation, in daily life, we can use the smart bracelet, or blood oxygen detector to detect their blood oxygen saturation, through the instrument can more accurately obtain their own blood oxygen saturation parameters.

Who should pay more attention to their blood oxygen saturation? The first is the group of regular smokers, because smoking can cause damage to the lungs and affect people's blood oxygen saturation; The second is hyperglycemia.

The group needs to pay more attention to their own oxygen saturation, and in general, the oxygen saturation of patients with high blood sugar is generally lower than that of normal people.

Blood oxygen saturation reflects the concentration of blood oxygen in the blood, which can be used to measure the ability of blood to carry and transport oxygen, and is an important physiological parameter of the human respiratory and circulatory system.

When the oxygen saturation is lower than the normal range, serious systemic complications will occur, such as: headache, dizziness, irritability, myocardial ischemia, heart failure, respiratory failure, etc.

The following 3 groups of people should pay attention to oxygen saturation:

1.People with cardiovascular disease.

Such as: coronary heart disease, hypertension, hyperlipidemia, cerebral thrombosis, etc.

Such patients have lipid deposits in the lumen of the blood vessels, narrowing of the lumen of the blood vessels, and poor blood flow, which will lead to difficulties in oxygen supply and make the body in a state of hypoxia all the time.

When the body is mildly deprived of oxygen for a long time, the function of vital organs such as the heart and brain will gradually decline.

Therefore, patients need to check blood oxygen and pulse changes every day in case they cannot receive it in time for severe hypoxia**, which is life-threatening.

2.People with respiratory diseases.

Such as: asthma, bronchitis, old and slow bronchia, pulmonary heart disease, etc.

When such patients become ill, they may have symptoms such as dyspnea and hypoxia, which can cause damage to vital organs such as the heart, lungs, brain and even kidneys to varying degrees.

Therefore, patients need to use an oximeter to measure their oxygen saturation to reduce the incidence of severe respiratory disease.

3.People who have been engaged in mental work for a long time.

This group of people, represented by white-collar workers, has excessive brain use and excessive oxygen consumption due to long-term work, and daily blood oxygen testing can make them vigilant and prevent major diseases early.

Oxygen saturation is the percentage of oxygen that is transported by red blood cells from the lungs to the rest of the body, and knowing how much oxygen your blood can carry can help you improve your overall health. People with respiratory problems, people with chronic diseases, people who snore, people who stay up late for a long time, etc.

Blood oxygen saturation is the oxygen content in the blood, whether it can reach a normal value, people with high blood pressure and cardiovascular and cerebrovascular diseases need to pay attention, so that they can make themselves healthier.

Generally speaking, people with high blood lipids and high blood sugar need to pay close attention to this indicator.

Obese people should try**. People who are overweight can have a low oxygen saturation due to breathing disorders during sleep. In addition, obesity increases the risk of sleep apnea.

After sleeping, if your blood oxygen saturation is below 90, you will need oxygen. If possible, you can buy a small medical oxygen concentrator, 1500-3000 can be bought. If the conditions are not enough, then two 50L oxygen bags must also be prepared for use every night until sleeping, the oxygen saturation of normal people is above 90, if the oxygen saturation is lower than 88.

Or the doctor diagnosed cor pulmonale.

<> or blood draws show a marked increase in red blood cells. In these cases, long-term oxygen inhalation is required**. In addition, the oxygen saturation monitor can detect not only the saturation of blood oxygen, but also the pulse rate and pulse strength.

The normal range of blood oxygen saturation is 98-100%, and the pulse is 60-100 minutes, if the test value does not meet the above indicators, the low blood oxygen content can be caused by the weakening of the person's cardiopulmonary function in one day, because the lungs are the organs that convert oxygen, and the human heart is the organ that transports blood and oxygen.

Blood type, as it is commonly referred to, refers to the type of antigen specific to the red blood cell membrane. There are 4 types of blood types of human beings: type A, type B, type O, and type AB, and the blood type of the person is determined from the date of fetal conception, and the blood type generally does not change. However, in a special temperament, the body constitution is stronger than that of other blood types, and type B blood has a wider range of food intake, so it is rare to be picky eaters, in addition, type B blood their immune system is very strong.

Therefore, blood type B will be called eating, and you have to shout hard to figure it out slowly, and her temperament is very slow, and her acute son mother of type O blood is not at all noble, he is not noble at all, he doesn't pay attention to anything every day, he is the opposite of me, probably this is one of the reasons why blood type B is aristocratic blood.

Blood oxygen saturation, also known as hemoglobin oxygen saturation, is the percentage of hemoglobin that binds to oxygen to reach saturation. It mainly depends on the partial pressure of blood oxygen, the state of subsaturation of blood oxygen saturation, the oxygenation function of the body, the early detection of hypoxemia, the improvement of the observation of critically ill patients, and the effective reduction of accidental deaths of patients. It can also be used to evaluate collateral circulation flow between the radial artery and ulnar artery, or dorsalis pedis artery and posterior carotid artery, to reduce complications of hand or foot blood circulation disorders, to evaluate the status of blood supply to amputated limb replantation, and to observe the occlusal state of patients after exercise.

It is important in the emergency room to monitor patients for apnea, cyanosis, severity of hypoxia, and respiratory failure.

Blood oxygen saturation can judge the ability of human blood to deliver oxygen, generally blood oxygen saturation is the best at 96%, and less than 94% is insufficient oxygen supply. Precautions: Hypoxia will affect the brain, cardiovascular system, liver and kidney function, and in severe cases, it can even be life-threatening.

I have been in Lhasa for 14 years, and my blood oxygen saturation is usually only 85 90. If you take oxygen, it is about 98, and your heart rate is only about 50. On physical examination, red blood cells are sometimes normal, and sometimes they are a little exceeded.

If oxygen is used for a long time, will it become dependent??? Thank you!

Blood oxygen saturation refers to the concentration of oxygen in the blood, and blood oxygen saturation is an important and commonly used indicator that effectively reflects whether the human body is hypoxic. Under normal circumstances, the body's blood oxygen saturation should be above 95%. If the oxygen saturation is below 95%, it indicates that the body is in a state of hypoxia.

There are many causes of this hypoxia, the common ones are heart failure and pulmonary embolism, emphysema and lung inflammation, which can cause hypoxia, and the symptoms are dyspnea, shortness of breath, fatigue and dizziness. In daily life, if there are such symptoms of hypoxia, you need to go to the hospital for a formal examination of cardiac ultrasound and CT of the lungs, combined with the examination, to determine what is the cause of the decrease in blood oxygen saturation.

Oxygen saturation (SAO2) is the percentage of oxygen-bound oxyhemoglobin (HBO2) volume in the blood to the total binding hemoglobin (Hb) volume, that is, the concentration of blood oxygen in the blood, which is an important physiological parameter of respiratory circulation. The functional oxygen saturation is the ratio of HBO2 concentration to HBO2+HB concentration, which is different from the percentage of oxyhemoglobin. Therefore, monitoring arterial oxygen saturation (SAO2) can provide an estimate of oxygenation and hemoglobin oxygen-carrying capacity of the lungs.

The oxygen saturation of normal human arterial blood is 98%, and venous blood is 75%.

The metabolic process of the human body is a biological oxidation process, and the oxygen required in the metabolic process enters the human blood through the respiratory system, combines with the hemoglobin (HB2) in the red blood cells to form oxyhemoglobin (HBO2), and then transports it to all parts of the human body. The ability of blood to carry and transport oxygen is measured by oxygen saturation. Thank you!

Disease analysis: blood oxygen saturation is an indicator to measure human health, used to mark the ratio of oxygen and hemoglobin in arterial blood to total hemoglobin, the oxygen saturation of healthy people is generally above 94%, and the pulse is between 60-100, if the oxygen content of the human body's blood is insufficient, it is easy to cause many complications, the most obvious point is dizziness and sleepiness, can not lift the spirit, easy to be irritable. If the blood oxygen content is insufficient for a long time, the cerebral cortex will be the most directly injured first, and if the brain is damaged, the harm to the human body is the most obvious, which will cause myocardial failure, poor blood circulation and other symptoms.

Oxygen saturation is the percentage of oxygen-bound oxygen and hemoglobin volume in the blood that can be bound to oxygen. Normal oxygen saturation is above 95%, about 95 100%, and venous oxygen saturation is 75%.

Oxygen saturation (SAO2) is the percentage of hemoglobin that is saturated with oxygen, which is the ratio of the oxygen content of hemoglobin to the amount of oxygen bound by 100.

Elevated: seen in hyperbaric oxygen**.

Decreased: seen in hypoxic lung disease such as emphysema, circulatory hypoxia, and tissue hypoxia.

Oxygen saturation is: the volume of oxygenated hemoglobin bound by oxygen in the blood as a percentage of the total volume of hemoglobin that can be bound, that is, the concentration of blood oxygen in the blood, which is an important physiological parameter of respiratory circulation. Normal people's oxygen saturation should reach 90% to 95% or more.

If the blood oxygen saturation is too low, the common symptoms are shortness of breath, fatigue, easy yawning, etc., and if the lack of oxygen is more severe, it can also lead to brain damage and even life-threatening.

1. People with vascular diseases (coronary heart disease, hypertension, hyperlipidemia, cerebral thrombosis, etc.).

2. People with respiratory diseases (including: asthma, bronchitis, old and slow bronchia, pulmonary heart disease, etc.).

3. High-intensity mental workers, working more than 12 hours a day.

In fact, it doesn't matter, this function seems to be useful, but most people are already uncomfortable when they know that their blood oxygen is low, and for people with different physiques, the accuracy and scope of application of the so-called data is still a huge question.

Blood oxygen refers to the oxygen in the blood, and the normal blood oxygen saturation of the human body is more than 95%. The higher the oxygen content in the blood, the better the person's metabolism. Of course, high blood oxygen content is not a good phenomenon, the blood oxygen in the human body is a certain saturation, too low will cause insufficient oxygen supply to the body, too high will lead to the aging of cells in the body.

Principles of Medicine

Human beings live on oxygen, which is inhaled from the lungs and enters the bloodstream through the capillaries, where it is transmitted to organs or cells in various parts of the body. The higher the oxygen content in the blood, the better the person's metabolism.

Of course, high blood oxygen content is not a good phenomenon, the blood oxygen in the human body has a certain saturation, too low will cause insufficient oxygen supply to the body, too high will lead to the aging of cells in the body.

Both O2 and CO2 are present in the blood in two forms: physically dissolved and chemically combined. Gas and hemoglobin exist in the form of complexes, if the oxygen concentration is large, hemoglobin cooperates with oxygen, if the concentration of carbon dioxide is large, bridge posture hemoglobin cooperates with carbon dioxide, in the arterial blood in the body, the oxygen concentration is large, in the venous blood in the body, the carbon dioxide concentration is large.

Blood oxygen saturation (also known as blood oxygen saturation or blood oxygen content) is an indicator of the amount of oxygen in the blood. Blood oxygen saturation is an important indicator of whether the human respiratory system is working properly.

Normally, the body's oxygen saturation is around 95%, but if the rubber oximetry is below 90%, symptoms such as dyspnea and fatigue may occur. Too low oxygen saturation may lead to insufficient oxygen supply to the brain, which can lead to problems such as memory loss and concentration loss.

Blood oxygen saturation can be increased by ventilators, oxygen, etc., all of which can help patients relieve symptoms such as breathlessness. In severe cases, hospitalization** may be required to improve oxygen saturation.
