For pediatric respiratory rate, 40-45 breaths/min for newborns, 30-40 breaths/min for those less than one year old, 25-30 breaths/min for 1-3 years old, 20-25 breaths/min for 4-7 years old, and 18-20 breaths/min for 8-14 years old are the normal respiratory range for children in a quiet, room temperature state. However, children’s respiratory rate is also affected by a variety of factors, such as strenuous exercise, fever, crying, or suffering from anemia, pneumonia, or hyperthyroidism, which can cause children’s respiratory rate to increase, and children’s respiratory rate will slow down when they sleep. Therefore, when assessing children’s respiratory rate, it is important to pay attention to the influence of the above factors to prevent errors.
