2. When systolic blood pressure below 100 mmHg is considered low blood pressure or low blood pressure.
3. The value between normal blood pressure and hypertension (systolic blood pressure from 120-139 mmHg or diastolic blood pressure from 80-89 mmHg) is called prehypertension .
4. If systolic blood pressure is below 120mmHg and diastolic blood pressure is below 80mmHg, it is called normal blood pressure .
