The Indirect Measurement of Blood Pressure

  • L. A. Geddes


One hundred twenty over eighty (120/80) and 90 mm Hg diastolic pressure are the numbers of interest to the general public and the cardiologist, respectively. The former (120/80) is a comfortable target for most people; 90 mm Hg diastolic is the flag for seeking signs of hypertension. As is well known, blood pressure increases with age in males and females; Fig. 1 illustrates this point.
