How much is the normal blood pressure of an 80-year-old person?

The normal range of blood pressure in 80-year-olds is systolic pressure 90-139mmHg, diastolic pressure 60-89mmHg.

With age, vascular elasticity weakens, blood pressure may gradually increase, so for 80-year-olds, blood pressure control targets can be relaxed appropriately, systolic pressure can be relaxed to 150mmHg below, diastolic pressure can be relaxed to 90mmHg
