Blood pressure varies in children of different ages; systolic blood pressure can be extrapolated using [age (years) x 2] + 80, and diastolic blood pressure is two-thirds of systolic blood pressure.
Children’s blood pressure is different from that of adults. Because the heart, elasticity of large blood vessels and other physiological structures are different from those of adults, the measurement of their blood pressure requires the use of special children’s cuffs and other equipment. Newborns and small infants can be measured with a monitor. In general, the younger the child, the lower the blood pressure.
Normal systolic blood pressure in childhood [age (years) × 2] + 80 for projection, diastolic blood pressure for the systolic blood pressure of two thirds of the unit of mmHg, diastolic blood pressure for the systolic blood pressure of 2/3, such as 6-year-old children systolic blood pressure is about 96 mmHg, diastolic blood pressure is about 64 mmHg. This is consistent with the age of the gender and height of the blood pressure reference standard.
If the child is taller and heavier, the standard can be appropriately relaxed. If there is a clear difference in blood pressure from the same age or the blood pressure of the extremities is not the same, it is recommended to go to the hospital in time for consultation.
