Is it necessary to take a lung CT? Why are we talking about this topic?
Many friends have asked me recently that many people have suffered from "white lung", which is really scary. Will ordinary people also suffer from "white lung" after being infected with the epidemic?
Speaking of "white lungs", it actually means that after the lungs accumulate water, CT cannot illuminate the lungs, so the lungs appear white on the films taken.
Will ordinary people suffer from "white lung" due to new crown ?
This problem must be viewed this way. First of all, the vast majority of COVID-19 patients have mild or common symptoms, which can manifest as symptoms of upper respiratory tract infection such as fever, fatigue, dry throat, sore throat, nasal congestion, runny nose, cough, etc., without involving the lungs. Therefore, no special examination of the lungs is required.
Secondly, for ordinary people who recover, their symptoms improve significantly or have no obvious symptoms, and the self-test antigen test is negative twice in a row (the interval between the two tests is greater than 24 hours). There is no need for examination. Even if there is a slight infection in the lungs, it will slowly heal on its own.
Third, for some patients, especially those with underlying diseases, such as the elderly, COPD, , bronchial disease, lung cancer, heart failure, , and renal failure, special care must be taken as they may be critically ill. At this time, a lung CT is very necessary.
It is best for such patients to have a blood oxygen monitor at home. If it is lower than 93, they should seek medical examination in time. If you are not prepared, you can also observe the symptoms. If you have a high fever for more than 3 days and are short of breath, more than 30 times per minute, it means that your lung function has declined, and you should seek medical treatment in time, otherwise it will easily become a critical illness.
In addition, special attention should be paid to pulmonary encephalopathy caused by hypoxia and carbon dioxide retention. This kind of lethargy is slightly different from the lethargy during fever. Pulmonary encephalopathy can cause varying degrees of consciousness disorder, ranging from lethargy and coma in mild cases to coma in severe cases. There may also be various movement disorders such as myoclonus and generalized tonic-clonic. Some people also show excitement, restlessness, increased speech, hallucinations, delusions, etc.
If a family member is drowsy for a long time, wake them up in time and ask some simple questions to see if they are conscious. Patients with underlying diseases must proactively take medication to control the primary disease when they are "yang". In addition, if you cough with phlegm, you should use some cough-relieving and phlegm-reducing drugs appropriately to keep your respiratory tract clear.
In this special period, Brother Tong is not a professional medical professional, but he also wants to find ways to collect some medical knowledge, hoping to help everyone. Of course, these contents are for reference only, and you should still seek medical consultation at critical moments.
Okay, I’ll be here first today. I’m Tong from Yitongbaidong. See you in the next issue.
