How much is the standard value of hypotension and hypertension

Hypotension is usually defined as a blood pressure lower than 90/60mmHg; hypertension is defined as a systolic blood pressure ≥140mmHg and/or diastolic blood pressure ≥90mmHg.

Under normal circumstances, the range of blood pressure measured at rest is systolic blood pressure 90-139mmHg and diastolic blood pressure 60-89mmHg. Hypotension mainly refers to a patient's blood pressure lower than normal, and a patient's upper limb arterial blood pressure lower than 90/60mmHg is generally hypotension. Hypertension is when the patient does not measure blood pressure on the same day without using antihypertensive drugs. Systolic blood pressure ≥140mmHg and (or) diastolic blood pressure ≥90mmHg measured in the clinic for 3 consecutive times is usually called hypertension.
