Recently, Zhang Li, deputy chief physician of the Respiratory Care Unit of Shanghai Pulmonary Hospital affiliated to Tongji University said: "The mortality rate of severe white lung patients is more than 40%, and some people can still be cured. But it is difficult to restore the lungs to their original clean state. Most of them Some patients will have sequelae of pulmonary fibrosis 
The left side is the white lung image, and the right side is the normal lung image
Others include bacteria , shock , and foreign body inhalation. squeezes . These reasons may cause damage to the lungs, producing a lot of mucus, exudate, inflammatory cells and other products that invade the lungs. In medical images , white areas of different sizes are shown. This is what we call the white lung phenomenon.
According to the current outbreak of new coronavirus pneumonia, most patients suffer from upper respiratory tract conditions such as fever and sore throat. A small number of patients will have symptoms of lung infection . Among them, the elderly and children are likely to develop because their own immunity is relatively low. It develops faster and their symptoms are not obvious. When the patient develops obvious symptoms, the disease will progress rapidly and even become severe.
Severely ill patients need to quickly arrange for oxygen inhalation and supplementary oxygen.
Therefore, we still need to focus on protecting these two key groups. Especially those who are older and have underlying diseases should pay more attention. Their diseases develop quickly and are not easy to treat. If possible, you can arrange for home oximeter to be tested. If the blood oxygen saturation is lower than 93%, , should be sent to the hospital in time.
For the elderly, blood oxygen testing can be done at home.
In short, no matter who of us has symptoms of persistent coughing and difficulty breathing, we must go to the hospital for treatment in time. Don’t hold on to this, as it may delay the condition. If a long-term cough does not relieve, for example, if it does not heal for more than two weeks, you should go to the hospital for a check-up to check whether there is any infection in the lungs.
#Experts say the mortality rate of severe white lung disease is more than 40%#
