Patients with hypertension need to have their blood pressure measured regularly to monitor whether it is being controlled smoothly. So, for hypertensive patients, how to measure accurate and effective blood pressure at home by themselves? 1, it is best to measure blood pressure at these times of the day: 6 to 10 am, 3 to 4 pm and before bedtime, in these three time periods to better grasp the fluctuations in blood pressure throughout the day; 2, if the blood pressure fluctuates when measuring blood pressure, you need to measure it 2 to 3 times more in each time period, and then take the average. For some patients whose blood pressure is particularly high at the first measurement, but not high or not significantly high for the second or third time, it is necessary to discard the first value and only add up the values of the last two times to take the average; 3. When taking the average of two consecutive measurements, the interval should be about two minutes, but there is no too strict time requirement, and a certain time interval is sufficient. Because if the patient always looks at the time during the waiting process, it will instead cause anxiety and cause a rise in blood pressure, resulting in inaccurate blood pressure measurement, then the interval time is meaningless. Doctor’s tip: The frequency of blood pressure measurement can be reduced with the blood pressure control, and under the guidance of the doctor, the frequency of measurement can be appropriately reduced according to the changes in different periods.
