What does venous pressure measure in dialysis procedures?

Venous pressure in dialysis procedures primarily measures the resistance that the blood encounters as it returns to the venous access site after being filtered through the dialyzer. This measurement is crucial because it helps detect any issues that may arise during the dialysis process, such as clotting in the dialysis system, kinks or obstructions in the tubing, or other complications affecting blood flow back to the patient. By monitoring venous pressure, healthcare providers can ensure that the dialysis treatment is functioning effectively and that the patient is safe during the procedure. If the venous pressure is too high, it might indicate resistance that needs to be addressed to avoid complications.
