Question
What Are the Normal Ranges for Children’s Heart Rate, Breathing, and Blood Pressure?
Answer
According to age, children’s heart rates gradually decrease. Newborns usually have a heart rate of about 120-140 beats per minute, infants under 1 year old have a rate of about 110-130 beats per minute, children aged 2-3 years have a rate of about 100-120 beats per minute, children aged 4-7 years have a rate of about 80-100 beats per minute, and children aged 8-14 years have a rate of about 70-90 beats per minute. Normally, children’s breathing rate is about 25-30 times per minute. The normal blood pressure value for children over 1 year old is systolic pressure = 80 (2 × age) mmHg, with diastolic pressure being two-thirds of the systolic pressure.
