High pressure 104mmHg, low pressure 74mmHg, in terms of its value is a normal blood pressure, for adults the normal blood pressure value refers to blood pressure less than 140/90mmHg, more than 90/60mmHg. for adults the high value of normal blood pressure refers to systolic blood pressure between 120-139mmHg, diastolic blood pressure between 80-89mmHg, and the normal ideal blood pressure is defined as a blood pressure less than 120/80mmHg, for high pressure 104mmHg and low pressure 74mmHg, is at normal blood pressure. In the normal state, when the measured high pressure value is greater than or equal to 140mmHg or low pressure value is greater than or equal to 90mmHg, you need to consider whether you have hypertension. It can be compared by regular measurement and recording. If the measurement is greater than the high value three times on non-same day, it is possible to have hypertension and further identification and diagnosis is needed. In addition, when measuring blood pressure, it should be noted that 30 minutes before the measurement, try not to do strenuous exercise, and avoid drinking coffee, tea and other drinks that can easily cause excitement, keep quiet when measuring, and make the sphygmomanometer, cuff and brachial artery measurement point on the same level, so as to ensure the accuracy of the measurement value.
