Pneumonia without symptoms, that is, without a series of symptoms such as fever, cough, cough, dyspnea, etc., should be diagnosed clinically by CT and sputum culture to clarify the diagnosis of pneumonia and select reasonable medication. Because the absence of symptoms is only a temporary phenomenon, with the accumulation of inflammation and uncontrollable infection, symptoms can appear at any time. CT can help to detect the characteristics of the pneumonia site as early as possible, which will guide the direction of treatment. Sputum culture can help people choose the right antibiotics, which is beneficial for controlling the disease. Appropriate application of sputum chemistry and percussion to drain sputum are helpful for pneumonia, and patients can inject thymopentin and take oral Jin Shui Bao to improve immunity.
