Lower lobe pneumonia of both lungs without symptoms should be identified as the cause of the disease and then treated specifically according to the diagnosis. If there is a clear infection, active anti-infective treatment is needed. Pneumonia asymptomatic in the clinic is called asymptomatic pneumonia, common in special germs infection such as atypical pathogenic bacteria infection, common in a small number of mycoplasma infections, imaging manifestations may appear small area of exudate. Lung exudates from non-infectious diseases, such as skin allergies in some patients can be followed by a small amount of exudate in the lungs. A small number of patients with tumors, connective tissue disease, and lung injury may also present without any respiratory symptoms. As well, patients with crushing pneumonia caused by prolonged bed rest may not have symptoms. If the patient is clearly suffering from bacterial pneumonia, the following treatment may be given. Bed rest, a high protein diet, and hydration. Involuntary pneumonia requires attention to positional changes to drain sputum. If the pathogenic bacteria are not clear, the medicine can be used empirically. Gram-positive cocci use penicillin, cefazolin, erythromycin. Gram-negative bacteria use cefazolin, amoxicillin, cefuroxime and so on. Nosocomial infections are treated according to the situation, mild and moderate can be used piperacillin, cefuroxime, cefuroxime, cefadroxil etc. Patients with asymptomatic pneumonia in the lower lobes of both lungs still require aggressive treatment. During the new crown epidemic, asymptomatic new crown infections also need to be isolated and treated to avoid causing the spread of the epidemic. The above medications need to be used under the supervision of a physician.
