significantly, What AVF means?
An arteriovenous fistula, or AVF, is an abnormal connection of vessels in the tissues around the brain or spinal cord in which one or more arteries are directly connected to one or more veins or venous spaces called sinuses.
also What is cannulation technique?
Antegrade cannulation has the arterial needle pointing in the direction of the bloodflow, that is, toward the venous limb. Retrograde cannulation has the arterial needle pointing toward the arterial anastomosis. 4 Either of these cannulation techniques can be used, with the choice being based on unit practice.
What problem will cause an increase in the patient’s venous pressure? An increase in total blood volume as occurs in renal failure or fluid retention through activation of the renin-angiotensin-aldosterone system increases venous pressure.

What should CVP be?
Normal CVP is between 0 and 8 cmH2O (1–6 mmHg). In a hypovolemic foal, CVP is often 0 cmH2O or less. Evaluating a response to fluid therapy (a progressive increase in CVP) is helpful in determining if fluid replacement is adequate.
What should venous pressure be during dialysis?
Dynamic venous pressure. Venous pressure is recorded at a pump speed of 200 mLs/min during the first 2-5 minutes of every dialysis treatment, using the same size fistula needle each treatment, usually 15 gauge. While baseline pressures vary with different machines, pressure readings should be close to 125-150 mmHg.
What is CVP?
From Wikipedia, the free encyclopedia. Central venous pressure (CVP) is the blood pressure in the venae cavae, near the right atrium of the heart. 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.

What is the difference between AV fistula and shunt?
