Measurement of blood pressure for the first time 150mmHg later are 130mmHg, then repeated measurements of 130mmHg is more accurate. The first measurement of blood pressure 150mmHg, is higher than the normal value of the state, after repeated measurements for the 130mmHg, suggesting that the subsequent measurement of blood pressure is relatively accurate, and multiple measurements belong to the average value, can represent the true level of blood pressure. If there is an abnormal level of blood pressure when measuring blood pressure, attention should be paid to reviewing it again and taking the average value of multiple measurements if necessary. Do not exercise strenuously, drink alcohol or smoke before taking a blood pressure measurement, otherwise the blood pressure level will rise briefly and will not be representative of the true level of blood pressure. Blood pressure levels are easily affected by many factors. It is important to be prepared to measure blood pressure and to ensure the accuracy of the measuring instrument in order to better measure blood pressure and to ensure that the blood pressure levels are true. If abnormalities in blood pressure are detected, prompt medical attention is recommended.
