Neonatal shortness of breath also has several causes, as follows: 1, respiratory problems: shortness of breath may occur when the child has pneumonia, respiratory infections; 2, other system diseases: including circulatory failure, shock, cardiac failure, which can cause changes in the child’s respiratory system, manifested as shortness of breath; 3, acidosis: electrolyte disorders, metabolic acidosis, or respiratory Acidosis may cause compensatory shortness of breath; 4. Physiological shortness of breath: because of the irregular rhythm of breathing in newborns, rhythmic breathing may occur, stopping for a few seconds and starting to breathe rapidly for a few seconds. So neonatal shortness of breath needs to be judged as shortness of breath when the body temperature is normal in a quiet state for more than 1 minute, and shortness of breath is only considered if it exceeds 60 times/min. If there are several sporadic accelerations of breathing, it should belong to physiological changes of respiratory rhythm and instability of respiratory rhythm. If there is shortness of breath, it should be judged according to the cause. If the respiratory rate is not greater than 60 breaths/min in a quiet state with a normal body temperature, it is possible that the respiratory rate is normal. If you do feel that your child has other comorbidities, including a poor complexion and poor milk intake, it may be a pathological condition that requires prompt diagnosis at the hospital.
