What does it mean if the arterial pressure exceeds the set limit?

When the arterial pressure exceeds the set limit, it suggests a potential dislodgement of the access needle or catheter. This condition can lead to complications such as reduced blood flow or hemolysis, and it is particularly significant in dialysis settings where maintaining adequate access is crucial for effective treatment. Elevated arterial pressure might indicate that the needle or catheter is not properly positioned, which can compromise the efficiency of the procedure and risk patient safety.

Dislodgment can impede proper blood flow, leading to alarm activations during treatment, which necessitates immediate assessment and corrective measures. Recognizing and responding to high arterial pressures promptly is vital for maintaining a safe and functional vascular access during hemodialysis.
