WebJan 17, 2024 · The portal venous pressure is the blood pressure in the portal vein and is normally 5–10 mm Hg. Variants of venous pressure include central venous pressure, which is a good approximation of right atrial pressure, which can then be used to calculate right ventricular end diastolic volume. Neurogenic and hypovolemic shock can cause fainting. WebThe diastolic pressure-volume relationship of either ventricle is a direct measure of the properties of its chamber. While this relation is, to a large extent, determined by the myocardium and its mechanical properties, there are a number of physiological factors that are also capable of influencing the diastolic pressure-volume-relation.
