Diastolic Pressure

Diastolic pressure

- **Blood pressure** is one of the most important characteristics of the cardiovascular system. It characterizes the force of blood pressure on the walls of the arteries. Under normal conditions, the diastolic phase lasts from 3.5 to 5 years - due to this, the diastolic pressure level changes slightly when measured over and over again. Over the first ten years of life, it drops by 20 mm Hg. Art., in the second ten – by another 15–20, then it becomes stable. On average, at school age, systolic blood pressure ranges from 110 to 140 mm Hg, and diastolic blood pressure ranges from 70 to 90 mm Hg. With age, the difference between the numbers increases - in adolescents 16-18 years old, diastole is almost equal to systole, and by adulthood it increases to 40-
