Whether or not pneumonia requires a hangnail, or infusion, is determined by the severity of the pneumonia and the symptoms it exhibits. Pneumonia refers to acute inflammation of the lung tissue, mostly bacterial pneumonia, but viral pneumonia, mycoplasma pneumonia, chlamydia pneumonia, and fungal pneumonia also exist. For common bacterial pneumonia, if the area of inflammation is small and the symptoms are mild, infusion therapy is not needed, but simply by oral medication, and the course of the disease is about 7-10 days. If the inflammation area is small and symptoms such as chills and high fever are apparent, infusion therapy is needed to improve the symptoms early to avoid adverse effects. If the inflammation is large and the symptoms are severe, especially if it is complicated by infectious shock, not only do you need infusion therapy, but you also need to be hospitalized immediately for observation and comprehensive treatment. Some cases of viral pneumonia may have severe symptoms at the beginning, such as chest tightness, wheezing, and hypoxia, and require immediate hospitalization for observation and infusion therapy.
