Evaluate blood pressure

To have your measured blood pressure values evaluated, enter them as integers (without comma) in the form above and click on the "Evaluate" button. Our calculator will then compare your values with the WHO blood pressure table and show you the result.

The systolic pressure describes the maximum blood pressure that occurs when the heart is pumping blood into the aorta (also called the upper value). The second value, the diastolic pressure, describes the blood pressure in the phase in which the heart relaxes and new blood flows into the heart chambers (also called the lower value). Both values are expressed in mmHg (millimeters of mercury).

Self-evaluate with the blood pressure table

The WHO blood pressure table distinguishes between 6 levels of blood pressure, each for systolic and diastolic pressure. A systolic pressure of less than 120mmHg and a diastolic pressure of less than 80mmHg are considered optimal. Up to 129 over 84, blood pressure is considered normal according to the WHO, and up to 139 over 89, high normal (i. e., slightly elevated but still within the normal range). After that, high blood pressure, known as hypertension, begins with 3 different degrees.

The blood pressure table of the German Hypertension League recognizes another level of high blood pressure, the so-called "isolated systolic hypertension". This is a strong difference between the systolic and diastolic pressure. Isolated systolic hypertension is when the systolic pressure is above 140 mmHg, i.e. in the hypertensive range, and the diastolic pressure is below 90mmHg, i.e. in the high-normal to optimal range. This strong deviation is considered a thoroughly alarming symptom that should be treated like any other type of hypertension.

What does pulse pressure mean?

Pulse pressure, not to be confused with pulse measurement, is the difference between the systolic and diastolic blood pressure values. According to studies, the risk of cardiovascular disease increases with increased pulse pressure. Furthermore, pulse pressure can provide information about the distensibility of the arteries.
