The symptoms of hypoxia, cyanosis and dyspnea in children with pneumonia are mostly mild pneumonia. If accompanied by mental depression, refusal to eat, gastrointestinal manifestations, neurological manifestations and organ manifestations, it should be considered whether the pneumonia is severe and requires hospitalization. Children with mild pneumonia who have mild fever, cough and shortness of breath, good mental status and good appetite do not need to be hospitalized and can be treated by outpatient nebulization, infusion or at home. 2. Children with severe pneumonia or children under 2 months of age with pneumonia who have severe fever, cough, shortness of breath and poor mental status need to be hospitalized for treatment. Since pediatric pneumonia is a respiratory tract infection that can be transmitted through the air, different types of pneumonia should be hospitalized separately as much as possible to avoid cross-infection. During hospitalization, children with pneumonia should have a light, hygienic, and easily digestible diet. Instead of cold drinks, they can eat noodles, thin rice, and lean meat soup. This is because hospitalization allows you to observe the child more carefully and give timely symptomatic treatment, such as aspiration and nebulization, so that you can use it in a timely manner and not be overwhelmed at home.
