What do systolic and diastolic blood pressure mean?

Systolic blood pressure refers to the side pressure caused by blood flow on the blood vessel wall during systole, while diastolic blood pressure refers to the side pressure caused by blood flow on the blood vessel wall during diastole.

Both systolic blood pressure and diastolic blood pressure are used to reflect the blood pressure of the human body. The normal value of systolic blood pressure in adults is 90mmHg-139mmHg, while the normal value of diastolic blood pressure is 60mmHg-89mmHg. However, systolic blood pressure and diastolic blood pressure can often be affected by emotions, diet, exercise and other factors. If the blood pressure returns to normal after removing the above factors, no special treatment is required. If the patient's blood pressure is higher than 140mmHg and (or) diastolic blood pressure is higher than 90mmHg at rest for three times or more than the same day, it is considered hypertension. If the systolic blood pressure is lower than 90mmHg and (or) diastolic blood pressure is lower than 60mmHg for multiple measurements, it is considered hypotension. Do

not exercise vigorously 30 minutes before blood pressure measurement. Keep the heart, upper arm and sphygmomanometer at the same level when measuring blood pressure. If the blood pressure value continues to be high or low, go to the hospital in time and actively carry out symptomatic treatment.
