What is the normal range of blood pressure in the elderly?

In the previous guidelines, the ideal range is that the blood pressure is controlled at 130 and the systolic blood pressure is within 130. However, according to further understanding, it is considered that if the blood pressure of the elderly drops too low, it may sometimes bring other risks, so the target value of systolic blood pressure of the elderly is about 150 mm Hg, and the target value of diastolic blood pressure is within 90 mm Hg.
