blood pressuremedical dictionary

<cardiology, physiology> The force that the circulating blood exerts on the walls of the arteries.

This measurement is divided into systolic (pressure during contraction of the heart) and diastolic (pressure during relaxation phase).

Blood pressure varies with age and sex of the individual. A rough rule of thumb for normal systolic pressure is 100 + Age of individual. In children 2 x (age) + 80 = systolic BP The diastolic pressure should be roughly 2/3 the systolic pressure.
