When assessing the lower extremities of a client with PVD, the nurse notes bilateral ankle edema. the edema is related to: increased venous pressure.
There are two ways that venous pressure might get up. Both when there is obstruction at the venous end and first when blood volume is enlarged.
What is central venous pressure?
- The blood pressure in the veins that lead to the heart's right atrium is known as central venous pressure (CVP).
- CVP measures how much blood returns to the heart and how well the heart can pump blood back into the arteries.
- Though the two terminologies are not the same because there can occasionally be a pressure difference between the venae cavae and the right atrium, CVP is frequently a decent approximation of right atrial pressure (RAP)
- When vascular tone is changed, CVP and RAP can vary.
- Changes in the slope of the venous return plotted against right atrial pressure can be used to visually represent this (when central venous pressure rises but right atrial pressure remains constant; VR = CVP RAP).
