A blood pressure of 139/95 mmHg is considered elevated, and multiple measurements should be taken to determine whether hypertension is diagnosed. Normal adult blood pressure is 90 to 139 mmHg systolic and 60 to 89 mmHg diastolic. Hypertension can be diagnosed if the diastolic or systolic blood pressure exceeds the upper limit of the above criteria when the patient is sitting quietly and the blood pressure in the brachial artery of the upper arm is measured three times in the clinic on non-same days. If the diastolic blood pressure exceeds the upper limit of normal value in the blood pressure of 139/95mmHg, it is considered elevated blood pressure, and if the blood pressure is still high after several measurements of blood pressure on non-same day, it is diagnosed as hypertension, and if the measurement of blood pressure is normal after that, it can be a transient elevation of blood pressure caused by emotional excitement, excessive exercise, and other factors, which is not high blood pressure. If the patient’s blood pressure rises several times, he should consult a doctor in time and follow the doctor’s instructions to carry out the appropriate treatment to control the blood pressure in a normal state, so as to avoid the disease from continuing to develop, which will have an impact on the patient’s physical health.
