In the 1920s, "normal" blood pressure was often interpreted loosely, with common medical advice suggesting a systolic pressure equal to 100 plus a person's age. However, data from that era indicates that average systolic pressures were typically between 120 and 135 mmHg for working-age adults, with 95 mmHg frequently cited as the upper normal limit for diastolic pressure.

What was a normal blood pressure in 1920?

The insurance company statistics of the 1920's were the basis for the acceptance of 95 mm. mercury as the upper normal limit of diastolic pressure. However, Boynton and Todd 24 found that about 4,500 (5 to 7 per cent.) of 75,000 presumably healthy students under 40 years of age had a diastolic pressure of over 90 mm.

What is the highest blood pressure anyone has ever had?

The highest pressure recorded in an individual was 370/360. With slow exhalation, the mean BP was 198/175 when the same 100% maximum was lifted (p < . 005).

Is 140/90 the new normal BP?

The new guidelines

Adults are now considered to have high blood pressure if their numbers read 130/80 millimeters of mercury (mm Hg) and higher. Under the old guidelines, high blood pressure was considered 140/90 or higher.
