Pneumonia cannot be completely diagnosed by auscultation or blood draw alone

Chest symptoms may not be obvious in the early stages, only the breathing sound is rough or the breathing sound is slightly reduced, subsequently, fixed middle and fine wet rales or twists may be heard, usually when crying, deep breathing, more under the back and on both sides of the spine, the end of deep inhalation in children is more obvious, the percussion is normal or there is a slight percussion dullness, reduced breath sounds, but when the scope of pneumonia expands to the entire lung lobe, the lungs may be full of inflammation and exudation, if one side of the lung is found to have a significant percussion dullness or decreased breath sounds, Consideration should be given to the presence of pleural effusion or atelectasis. Auscultation alone or blood draw cannot be completely diagnosed, and chest x-ray is recommended when there is a high suspicion that a child has pneumonia, because the chest x-ray has a high density of patches after the child has pneumonia, which is very helpful for the diagnosis of pneumonia. When children take chest X-ray, the amount of radiation is very small, and the exposure time is particularly short when shooting, and the impact on children's bodies is negligible, and parents do not need to worry too much.
