The standard comparison table of blood pressure for 10-year-old children is systolic blood pressure (mmHg) = (age * 2) + 80, diastolic blood pressure is 2/3 of the systolic blood pressure, so 10-year-old children’s blood pressure around 100/66mmHg is normal. Children’s blood pressure range is not the same as adult’s, the younger the age the lower the blood pressure, according to the formula, 10-year-old children’s systolic blood pressure of 100mmHg, diastolic blood pressure of 66mmHg is the normal range, you can refer to this standard. If the blood pressure of 10-year-old children is too high or too low, you need to consider whether there is high blood pressure or low blood pressure, you can go to the hospital in a timely manner to do the examination, to identify the causes of abnormal blood pressure, and then intervene in the treatment. Usually pay attention to monitor the growth and development of children, if there is any abnormality, consult a doctor in time.
