What is the normal value for pressure?

GOOD DAY DR I WOULD LIKE TO KNOW WHICH IS MORE OR LESS THE MEASUREMENT OF PRESSURE FOR AN OLD 74 YEARS, BECAUSE I MEAN THIS 17 BY 9 SHE TAKES CAPTOPRIL 25 I WOULD LIKE TO KNOW IF THIS HIGH
Expert answer:

The normal pressure should not exceed 14 by 9 (some think that the maximum values ​​should be 12 by 8), any value above that is considered high. In elderly patients due to hardening of the arteries we may even consider values ​​of blood pressure to be somewhat higher than normal, but each case should be evaluated in isolation.
