Normal adult blood pressure range?

The normal range of systolic blood pressure is 90 ~ 139 mmHg, diastolic blood pressure is 60 ~ 89 mmHg, and pulse pressure is 30 ~ 40 mmHg. Abnormal blood pressure: hypertension: under the premise of not using antihypertensive drugs, the systolic blood pressure of adults above 18 is ≥ 140mmHg and/or the diastolic blood pressure is ≥90mmHg. Hypotension: Blood pressure is lower than 90/60mmHg. It is called arterial blood pressure, capillary blood pressure and venous blood pressure in different blood vessels, and blood pressure usually refers to arterial blood pressure in systemic circulation.

Matters needing attention in measuring blood pressure: 1. Sphygmomanometer should be tested and calibrated regularly to maintain accuracy. 2. For people who need to closely observe blood pressure, they should be "four-set", that is, set time, place, position and sphygmomanometer. 3. There are no factors affecting blood pressure such as strenuous exercise, smoking and emotional changes within 30 minutes before the measurement. The mood is stable and the cuffs should not be too tight. 4. Choose the appropriate cuff as needed. 5. Don't inflate too fast or too hard to prevent mercury from overflowing; Bleeding should not be too fast or too slow to avoid reading errors. 6, found that blood pressure can't hear clearly or abnormal, should be retest. When re-measuring, do not measure until the mercury column drops to "0". 7. Measure the contralateral arm of hemiplegic patients. Baidu encyclopedia-blood pressure
