Baby’s labored breathing may be related to respiratory tract obstruction, preterm infant respiratory distress syndrome, heart disease, central nervous system disease and so on. 1. Respiratory tract obstruction: baby’s upper respiratory tract obstruction such as nose blockage, laryngeal or laryngeal bone hypoplasia, upper respiratory tract narrowing or obstruction, inhalation of foreign objects and other factors can cause inspiratory dyspnea. Lower respiratory tract obstruction such as bronchitis, bronchial asthma can cause expiratory dyspnea. 2. Preterm respiratory distress syndrome: babies born within 34 weeks may not have fully developed lungs and the respiratory system is not perfect enough, so preterm respiratory distress syndrome may occur, causing respiratory distress. It often occurs shortly after birth. 3. Heart disease: such as congenital heart disease, abnormal development of the heart and large blood vessels can cause hemodynamic abnormalities in the baby, resulting in the inability to supply oxygen properly, which can also cause respiratory distress in babies. 4. Diseases of the central nervous system: such as encephalitis, meningitis or brain tumors, etc., can also lead to problems with the respiratory center, resulting in respiratory distress in babies. Baby breathing difficulty, there may also be other reasons, it is recommended to go to the hospital in time, improve the examination to clarify the cause of the disease, under the guidance of the doctor to give targeted treatment or treatment.
