The criteria for the recovery of pneumonia in children need to be judged from the clinical symptoms, signs and symptoms of the examination, and the indicators of the review. 1. Clinical symptoms: the recovery of pneumonia in children generally requires that the body temperature returns to normal and lasts for more than three days, and that the patient’s symptoms of coughing and coughing up sputum improve significantly compared with the previous symptoms. 2. Clinical signs: When performing respiratory auscultation, the dry and wet rales in both lungs are basically absorbed, and the respiratory sounds in both lungs are clear, which is the main criterion for recovery. 3. Indicators for review: The indicators for review include routine blood tests, lymphocyte and white blood cell counts returning to normal range, and absorption of lesions on chest X-ray. Children with pneumonia, clinical symptoms and signs as the main criteria, chest imaging tends to absorb more slowly, therefore, there is a certain lag. Parents can take their babies for regular follow-up of pneumonia.
