Healthcare providers consider a normal blood pressure reading to be 120/80 or below. However, it can actually fall anywhere in a range from 90/60 to 120/80 -- it's not just one set number. The number on top of the reading is called the systolic pressure.
The unit of BP is millimeters of mercury (mmHg). The normal blood pressure range for adults is 120-80 mmHg (systolic should be below 120, while diastolic should be below 80). The ideal blood pressure for men and women (even for women over 40 and for women over 50) can be slightly different.It is a scaring fact that more and more children are diagnosed with high blood pressure every year. BP higher than the normal levels is referred to as high BP (HBP) or hypertension.ccording to the U.S. Department of Health and Human Services, people are said to have prehypertension when their blood pressure levels are slightly higher than normal. The systolic BP can be in between 120 and 139 and the diastolic BP can be between 80 and 89.
