Don't think that it's okay if you don't have symptoms! The "big trick" of COVID-19 kills people invisible
The epidemic situation that has become increasingly tense in recent days can be said to be breathless. The huge pressure on front-line medical staff is unimaginable. With the extension of the level 3 alert to June 14, I am afraid that all office workers will have to live at home. Gotta keep going. What’s even more nerve-wracking now is that COVID-19 has a trick up its sleeve, making it completely impossible for asymptomatic patients to notice that they are infected. By the time they have difficulty breathing and their faces turn black, it’s already too late? What is the terrible killer trick that not only causes headaches for medical staff, but also causes the number of sudden deaths at home to gradually increase?
COVID-19 kills invisible people in three easy ways to kill people with a knife
Scientists have studied how COVID-19 attacks the body’s lungs, and the most deadly “nirvana” is to make the body “Silent Hypoxia.” Invisible hypoxia is not only seen in patients, but also occurs in mountaineers and pilots. Because their location is too high and the air pressure decreases, the oxygen inhaled into the lungs decreases every time, and the body is prone to hypoxia unconsciously.
One of the sure-kill tricks of the COVID-19 virus is to slowly deprive the infected person’s body of oxygen. The patient does not feel difficulty breathing in the early stage and may think the symptoms are mild and do not seek medical treatment in time. However, as time goes by, he will gradually feel difficulty breathing. Chest tightness, and the condition was already quite critical at this time.
Bella. Professor of Medical Engineering and Materials Engineering at Boston University. Bela Suki and biomedical engineer Jacob. Jacob Herrmann published a paper in the journal Nature Communications. In their research, they used computers to model three invisible hypoxia situations:
First of all, generally speaking, after the lungs are injured, blood vessels will constrict under normal conditions, allowing blood to flow to the lung tissue that is full of oxygen. However, COVID-19 will damage the function of the lungs and prevent the blood from carrying oxygen, causing the body’s oxygen content to slowly become low. Second, when the blood vessel walls become inflamed due to COVID-19 infection, blood clots will coagulate in the lungs, which can also cause hypoxia. Third, COVID-19 can cause an imbalance in blood oxygen supply, which is also seen in many respiratory diseases (such as asthma). Such supply imbalances.
The confirmed patient “refused to seek medical treatment” and died suddenly at home? Don’t lose your life because of face issues!
In general, the COVID-19 virus is cunning and dangerous in that it can spread invisible and may cause invisible hypoxia. Relevant studies have found that the virus has the ability to spread in asymptomatic patients for 14 days, which is enough to greatly increase the risk of community infection. Therefore, many foreign experts also recommend that patients who are isolated at home use blood oxygen monitoring and other equipment to pay attention to their blood oxygen concentration at all times to avoid falling into invisible hypoxia without knowing it.
In fact, for patients with pneumonia, monitoring blood oxygen levels is very important. A blood oxygen level below 95% may indicate mild pneumonia, while a blood oxygen level below 90% may indicate severe pneumonia. The Taiwan Epidemic Command Center also issued blood oxygen detectors to 690 confirmed cases in the quarantine center to allow them to test their blood oxygen concentration. If there is a change in blood oxygen, they will be sent to the hospital immediately for treatment.
As the old saying goes, “Know yourself and the enemy, and you can fight a hundred battles without danger.” In this war with the virus, humans still do not have enough understanding of COVID-19, let alone requiring the general public to pay attention to the dangers of “invisible hypoxia.” At present, there have been reports of several cases of confirmed cases of confirmed cases of people dying suddenly at home because they refused medical treatment in Taiwan, and most of them were elderly people over 60 years old. It can be seen that after COVID-19 mutates, patients may think that they are still healthy, or even have mild symptoms and not care, which eventually leads to irreversible consequences.
If your relatives or friends have symptoms and have a history of high-risk contact, remember to call 1999 for assistance. Don’t get infected by COVID-19 because you are not paying attention!
