The normal respiratory rate for children is 40-45 breaths/min for newborns at quiet, room temperature; 30-40 breaths/min for children under 1 year old; 25-30 breaths/min for children 1-3 years old; 20-25 breaths/min for children 4-7 years old; and 18-20 breaths/min for children 8-14 years old. There are certain differences in respiratory rate for children of different ages, and prompt medical consultation is recommended if the respiratory rate is abnormal. Reasons for abnormal breathing 1, physiological factors: children’s respiratory rate is affected by a variety of factors, such as strenuous exercise, fever, crying, which can lead to a temporary increase in respiratory rate; 2, respiratory tract infection: bacterial and viral infections, causing mucosal edema and increased secretions, which hinder normal breathing, can lead to faster and deeper breathing; 3, pediatric respiratory failure: central and peripheral respiratory disorders due to various reasons, manifesting for shallow and fast breathing, respiratory rate >45 times/minute, infants and children can even reach 80-100 times/minute, respiratory slowdown can occur after muscle fatigue. If a child has an abnormal respiratory rate, he or she should seek medical attention and treatment for the cause. In case of infection, cefixime can be taken as prescribed by the doctor for anti-infection, and if accompanied by neonatal cerebral edema, etc., mannitol can be used as prescribed by the doctor for treatment.
