pulse pressure measures the actual driving force, the kinetic energy of the heart.
One can only approximate it and say that the pulse pressure is low or high.
If the systolic pressure does not also rise, as in a normal heart following exercise, we will say, the pulse pressure falls.
We know that when the pulse rate is constant, vasodilatation causes a fall in diastolic pressure and a rise in pulse pressure.
In all high pulse pressure cases, in which the pulse pressure is over 70 mm.
On the contrary, vasoconstriction causes a rise in diastolic pressure and a fall in pulse pressure.
The diastolic does not fall to the same extent as the systolic so that there is a pulse pressure smaller than normal.
Hg lower than the systolic pressure, and consequently these figures represent the pulse pressure in the brachial artery of man.
In all surgical diseases the most important fact to know is not the systolic pressure, but the pulse pressure.
The pulse pressure varies under normal conditions from 30 to 50 mm.
pulse pressure n.
The variation in blood pressure occurring in an artery during the cardiac cycle; the difference between systolic and diastolic pressures.
