The signs of improvement of pediatric bronchopneumonia are mainly the following: i. The body temperature gradually decreases to normal, the symptoms of cough and sputum are significantly reduced, and the sputum changes from yellow pus sputum to white mucous sputum. The child’s appetite and mental state improve significantly. Blood count usually decreases to normal, and calcitoninogen and C-reactive protein also tend to decrease. Chest radiograph or chest CT shows significant absorption of inflammatory exudate in both lungs. Once pediatric bronchopneumonia has been treated with the above-mentioned manifestations, it often suggests that the pneumonia is improving, but of course the pneumonia needs active anti-infection treatment in the process of getting better.
