As an example: if systolic blood pressure = 120 mmHg, diastolic blood pressure = 80 mmHg, right atrial mean pressure = 3 mmHg and cardiac output = 5 L/min, Then mean arterial pressure = 2 x diastolic pressure + systolic pressure/3 = 93.3 mmHg, and SVR = (93 - 3) / 5 = 18 Wood units, or equivalently 1440 dyn·s/cm 5.
Mean arterial pressure (MAP) is the average of blood pressure over a cardiac cycle and is determined by the cardiac output (CO), systemic vascular resistance (SVR), and central venous pressure (CVP): [2] [96] [97]
CVP reflects the amount of blood returning to the heart and the ability of the heart to pump the blood back into the arterial system. CVP is often a good approximation of right atrial pressure (RAP), [1] although the two terms are not identical, as a pressure differential can sometimes exist between the venae cavae and the right atrium. CVP and ...
If healthy blood pressure is no higher than 120/80, but blood pressure is not viewed as a problem until it hits at least 140/90, consider all the damage that is being done before any intervention ...

Regarding ideal numbers, the famous M.D. says: "Your blood pressure is supposed to be under 140 over 90, optimally closer to 120 over 80." ... 15 low-stress, high-paying jobs to pursue. Food. Food ...
In medicine, the mean arterial pressure (MAP) is an average calculated blood pressure in an individual during a single cardiac cycle. [1] Although methods of estimating MAP vary, a common calculation is to take one-third of the pulse pressure (the difference between the systolic and diastolic pressures), and add that amount to the diastolic pressure.
A normal blood pressure reading is less than 120/80 mm Hg, while high blood pressure, or hypertension, is considered 130/80 mm Hg or higher, according to the American College of Cardiology and ...
