What are potential causes for increased arterial pressure during dialysis?

Increased arterial pressure during dialysis can be primarily attributed to kinks or occlusions in the arterial line. When there is a blockage or constriction in the arterial line, it creates resistance to the flow of blood from the patient to the dialysis machine. This resistance causes the blood pressure in the arterial line to rise as the pump has to work harder to push the blood through the restricted area.

It's important to monitor the arterial pressure closely during the dialysis process, as persistent high pressure can lead to complications and indicate that there may be a malfunction or a need for adjustment in the line setup. Identifying and addressing kinks or blockages allows for improved blood flow, ensuring that dialysis can be performed effectively and safely.
