High pressure, i.e., systolic pressure of 112 mmHg, and low pressure, i.e., diastolic pressure of 81 mmHg, are normal.
Clinical studies show that a healthy adult’s blood pressure range of 90/60 to 120/80 is normal. However, whether a patient’s blood pressure is normal also depends on whether the blood pressure measurement is accurate and appropriate.
Proper measurement of blood pressure requires the patient to be at rest, avoiding strenuous exercise, emotional excitement, drinking coffee, and alcohol products, which can affect the blood pressure measurement. Taking a sitting or supine position, the position of the cuff is placed on the brachial artery of the upper arm at the same level as the heart, and the tightness should be empty one finger. It is generally required to measure 3 times on non-same day and take the average value in the middle.
If it is after activity, emotional excitement, or the result of 1 measurement, it can not be judged as normal high value blood pressure. This is because staying up late, stress, high stress, prolonged high salt diet, and measurement after activity may all lead to elevated blood pressure.
If the systolic blood pressure ≥ 140 mmHg and/or diastolic blood pressure ≥ 90 mmHg after measurement of blood pressure, the criteria for diagnosis of hypertension may be met. It is necessary to consult the hospital and further improve the examination to clarify the diagnosis.
