Venous pressure monitoring,,,,
It is to monitor extra-corporeal blood pressure within in the bloodline while returning to the patient. A low pressure indicates a good flow back to the patient whereas a high positive pressure indicates some form of obstruction from the venous return site to the venous chamber of the venous bloodline set.
A higher positive pressure is expected when the blood pump speed increases. The positive pressure registered will normally be at about the same as the blood pump speed or lower.
A much higher positive venous pressure can mean that a wrong choice of AVF needle size or misalignment of the AVF needle. Pre-emptive action must be taken or else back pressure may occur resulting in clotting of the dialyser.
