As the number of people infected and recovered from the new coronavirus increases, people have a better understanding of the symptoms and duration of the disease when the new coronavirus occurs. They also have some understanding of the serious consequences that the new coronavirus may cause. For example, many people have heard of "white lung". So, what is "white lung", and what will it feel like and manifest when it occurs? How to detect early?
[Doctor Comment]
New coronavirus is a disease caused by infection with the Omicron virus. virus mainly invades the upper respiratory tract such as the nose, pharynx, and larynx. When the lower respiratory tract such as the trachea and lungs are invaded by the virus, it will cause viral pneumonia . "White lung" is a result of pneumonia , which is a more critical disease.
The so-called "white lung" is actually a description on imaging . For example, a clean empty glass bottle looks completely transparent at first glance. When the glass bottle is filled with turbid sewage, the bottle is no longer transparent and looks like a fog, which is similar to "white lung".
As we all know, the lungs are respiratory organs, and a large amount of gas exchange needs to be completed in the alveoli of the lungs. Under normal circumstances, there is only air in the alveoli, just like a clean glass bottle; when the Omicron virus invades the alveoli and causes an inflammatory reaction, a large amount of inflammation When sexual exudate leaks into the alveoli, the "glass bottle" will no longer be transparent. The alveoli will be occupied by liquid and can no longer complete gas exchange. The body will cause a series of problems or even life-threatening problems due to hypoxia. The consequences are still serious. The lung CT examination can clearly show that the lungs are white.
It can be seen that the main manifestation of "white lung" is the symptoms of hypoxia, such as shortness of breath, chest tightness, confusion, lethargy, coma, etc., but if it occurs in In the elderly, due to their reduced ability to respond, coupled with COVID-19 fever, body aches and other conditions, they often cannot be detected in time. However, severe hypoxia has actually occurred. At this time, the blood oxygen saturation will show that it is lower than the minimum limit of 95%, and they need to be sent to the hospital immediately for treatment.
Therefore, if you have elderly people at home, you can buy a finger-clip oximeter, which can detect blood oxygen saturation at any time. Clip it on your finger and you can get the result in a few seconds. It can be used as a daily monitoring tool at home to monitor whether the elderly have hypoxia, respiratory failure, etc. Respiratory failure , etc.
If there is no oximeter , you should pay attention to observe and measure the number of breathing and heart rate speed. When the respiratory rate is greater than 30 times/minute and the heart rate exceeds 120 times/minute, it indicates that hypoxia may have occurred. For people with COVID-19, when the fever recurs for more than 5 days, they should also pay attention to whether the Omicron virus has invaded the lower respiratory tract. It is recommended to go to the hospital for a lung CT examination in time to achieve early prevention and early treatment of white lung.
