What is white lung?

As for the problem of large white lungs and silent hypoxia, a reader once described that " My mother was 70 years old, five or six days after the COVID-19, and did not have a fever. Suddenly feel hold my breath, and go to the hospital to check the discovery is viral pneumonia, the lung is white.”

In this regard, Henan Province people's Hospital geriatric medicine Wu Wenjuan introduced, "white lung" from the medical point, there are two aspects of the situation.

One is the original lung diseases, such as pulmonary fibrosis, tuberculosis, etc., the lungs are damaged, imaging colloquial description will see the white lungs.

There is also a clinically more severe manifestation of viral pneumonia.

Normally, the lungs are made up of alveoli, which are filled with air. For CT or X-ray examination, it should show black areas. But if there is inflammation and infection in the alveoli when there are exudate and inflammatory cells, the alveoli are filled with these exudate or inflammatory cells, radiation will not penetrate through, in the imaging performance on the white area, is what we say " white lung.”

How to prevent it?

"There is no prevention, but only early warning."Henan Provincial People's Hospital geriatric medicine Wu Wenjuan said, according to the novel coronavirus infection, recommended the elderly over 80 years old, with positive symptoms, to timely contact community doctors, or usually familiar with the attending doctor contact, according to the situation diagnosis, need home observation treatment or hospitalization treatment.

So for people under 80 years old, the physical condition is also good, or have hypertension, diabetes, etc., but the control is very good, very stable, want to home observation and treatment, what changes need to be vigilant?

Wu Wenjuan said that the "white lung" caused by viral pneumonia is not immediately formed, generally in two or three days before there are some signal warnings, we must pay attention.

For example blood oxygen saturation, heartbeat, pulse, and other changes.

1. Remind everyone: after the old people in the home have a fever, first of all, observe their mental state, whether drowsiness, loss of appetite, apathy, vomiting, and other conditions.

2. There are many elderly people with basic diseases, generally recommend to prepare a fingertip oximeter at home.

Two changes can be noted: oxygen saturation and pulse. If the oxygen saturation is below 93 or 90, pay more attention; the normal pulse is 60 to 100, above 100. Someone monitoring found that the old man walking activities, the value in 95,96 is also good, but a rest, immediately ups and downs "from 95,96 immediately fell to 93 or below", also should pay attention to.

3. Some people say that the old people in the family are usually in good health, and also do not have a blood oximeter. What data should you look at? Wu Wenjuan suggested that in addition to the elderly's mental state, you can also count their breathing frequency. In the elderly rest state, a minute to count, if more than 30 times, also need to be more vigilant. If the frequency of breathing is not clear, it can also be counted by the frequency of thoracic activity. Generally speaking, appear above changes, it is necessary to contact medical institutions in time, do a further examination, and diagnose treatment. In addition to the foundation of the elderly, the elderly, Wu Wenjuan reminded, too obese people, even young and middle-aged, infected should pay attention to and be vigilant.
