There is no standard normal range for blood pressure in the ankle, generally the default normal blood pressure value is the upper arm blood pressure as a reference, the range is 90~140mmHg/60~90mmHg, and the blood pressure in the ankle is generally a little higher than the upper arm blood pressure value. Before measuring blood pressure, you need to rest for 5 minutes, and avoid emotional excitement, drinking coffee, smoking and other stimulating foods, so that the body is in a relaxed state. However, due to the distance between the ankle blood pressure and the heart, the resulting blood pressure measurement is not as accurate as that of the upper extremity, and it is more recommended to use the blood pressure measurement of the upper extremity. If the patient’s blood pressure is higher than the normal range, please go to the regular hospital for a detailed examination, and at the same time need to develop good living habits, such as low-salt and low-fat diet, close monitoring of blood pressure, increase exercise, and if necessary, take medication under the guidance of a physician.
