Indicators in the human body, many people pay more attention to blood pressure , blood sugar, heart rate , etc., but they ignore the blood oxygen content. As everyone knows, it is also one of the vital signs, and whether it is at a normal level has a lot to do with human health.
As we all know, we cannot do without oxygen , and blood oxygen is the oxygen content in the blood. What is the normal blood oxygen level in the human body? If it's low, what will happen to your body? Is the higher the better? Is it necessary to prepare oxygen concentrator at home? Let me tell you about it below.
Under normal circumstances, the indicator of blood oxygen saturation is commonly used in clinical practice. The oxygen saturation of arterial blood in the human body is about 95%-100%, and the oxygen saturation of venous blood is about 75%.
Oxygen is vital to people, so is the higher the blood oxygen level, the better?
is not true. Excessive will affect health and cause cell aging. Excessive inhalation can easily increase the risk of oxygen poisoning . It is the same as immunity . It is not a good thing if it is too high or too low. It is healthy if it is within the normal range.
If the level is between 90%-94%, it means that the oxygen supply is insufficient. It may not be obvious at ordinary times, but when you exercise, you are prone to chest tightness and other discomforts.
If is lower than 90%, it is considered hypoxemia. This condition is generally more common in patients with respiratory diseases. Even if there is no exercise, chest tightness and shortness of breath are prone to discomfort in a calm state.
Many people may not understand that we breathe air every day, why does it cause low blood oxygen?
This has something to do with the high pressure of modern people. The mind and body will affect each other, and psychological factors will affect physiological factors. When people are in a state of excessive pressure for a long time, oxygen consumption is easy to increase.
Unreasonable and unhealthy living habits can also cause hypoxia. For example, many people now hardly exercise every day. If they do not exercise for a long time, their ability to absorb oxygen will also be affected. Some people rely too much on air conditioning, and if they stay in an air-conditioned room for a long time, the lack of air circulation will also have an impact. Or eating irregularly, often overeating, increasing the metabolic burden on the body, which also requires more oxygen.
What impact does low blood oxygen saturation have on human health?
The level is lower than normal. In addition to the above-mentioned discomfort of chest tightness and shortness of breath , brain health will also be affected. Lack of oxygen may cause headaches and memory loss . The cardiovascular system will also be affected, which may cause myocardial ischemia . If it lasts for a long time, the impact on health cannot be ignored.
For the elderly, we should be wary of "silent hypoxia"
As mentioned above, when blood oxygen is insufficient, the human body is prone to some discomfort, but for elderly people, the adverse reactions may not be obvious. Zhang Wenhong, director of the Department of Infectious Diseases at the Fudan University Affiliated Scratch Hospital, said that some elderly patients are sent to the hospital too late because their hypoxia response is relatively slow, and some cannot feel chest tightness and other abnormalities. This situation can be called silent hypoxia.
For the elderly, if they are infected with the new coronavirus, they should pay close attention to whether they have chest tightness, difficulty breathing and other discomforts during home treatment. If they occur, they should seek medical treatment in time and do not take it seriously. For people over 80 years old, they should seek medical treatment directly after infection.
So, after getting positive, do you need to prepare blood oximeter, , and oxygen concentrator for home use?
Generally speaking, most infected people do not need .Peng Zhiyong, director of the Department of Critical Care Medicine at Zhongnan Hospital of Wuhan University, said that if there are elderly people at home, it is important to monitor the blood oxygen saturation. If it is lower than the normal value, oxygen needs to be inhaled in time and sleep on the stomach as much as possible. If it cannot be relieved, seek medical treatment promptly.
Regarding oxygen inhalation machines, generally speaking, if the elderly do not have basic diseases and have also received the new crown vaccine, there is no need to prepare. If you have underlying diseases and are worried, you can prepare one if possible.
If you need to inhale oxygen, I would also like to remind everyone to use it scientifically and in accordance with the doctor's instructions. It is not advisable to use it by yourself to avoid using it incorrectly and affecting your health. Regarding the oxygen inhaler, everyone should also pay attention to it. It is an auxiliary device and does not play a role in treating diseases.
Therefore, I hope everyone can view these devices rationally. Not everyone needs them, and don’t blindly follow the trend to buy them. For those who need them, it makes sense to use them. If you don’t need them, using them improperly will be counterproductive.
What can we do to keep blood oxygen at normal levels?
Moderate and regular exercise is necessary. It can exercise cardiopulmonary function, strengthen breathing ability, help maintain blood oxygen levels, and is also helpful for enhancing immunity and resistance . However, I would like to remind everyone that if you are infected with the new coronavirus, you should pay more attention to moderate exercise. You should also be careful not to engage in strenuous exercise immediately after recovery. You should gradually resume exercise step by step, and do not be too eager to make up for what you have missed before.
It is recommended that everyone should pay attention to the balance between work and rest. Do not sacrifice your rest time to play games on your mobile phone , which will increase the burden on the organs in the body.
In summary, the blood oxygen content in the human body has a great impact on physical health. Both too low and too high are not good. Take a look at the above physical manifestations of low blood oxygen. I hope you have none. For the elderly, they should be wary of silent hypoxia and pay attention to monitoring some indicators in the body during the infection. When the body experiences chest tightness and other discomforts, seek medical attention as soon as possible.
