A blood pressure of 58-108 mmHg, which is generally defined as a diastolic pressure of 58 mmHg and a systolic pressure of 108 mmHg, is abnormal and falls within the range of low blood pressure. Generally speaking, blood pressure is the side pressure of blood on blood vessels. A normal adult has a systolic blood pressure of 90-119 mmHg and a diastolic blood pressure of 60-79 mmHg. A systolic blood pressure of ≥140 mmHg and/or a diastolic blood pressure of ≥90 mmHg is considered to be high blood pressure; whereas a systolic blood pressure of <90 mmHg and/or a diastolic blood pressure of <60 mmHg is considered to be low blood pressure. Therefore, a blood pressure of 58-108 mmHg is abnormal and is considered hypotensive, and the pulse pressure difference is large. Differential pulse pressure refers to the difference between systolic and diastolic blood pressure, with a normal value of 30-40 mm Hg. A differential pulse pressure of 50 mm Hg at a blood pressure of 58-108 mm Hg is an abnormal level, and can be further investigated to determine the cause. Blood pressure 58-108mmHg, it is recommended to consult a doctor in a timely manner, follow the doctor's instructions for examination and treatment, do not take medication without authorization, in order to avoid medication is not appropriate, damage to the body, and delay the condition.
