Arterial pressure should never be more negative than which value?

Explanation:
Arterial pressure on the dialysis access is a negative-suction measurement, and keeping it within a safe range protects the access and patient. If this pressure becomes more negative than about -250 mmHg, the suction can cause the cannula or vessel to collapse, lead to infiltration into surrounding tissue, or draw air into the circuit. To prevent these risks, machines are set with a safety limit so the arterial pressure should never go beyond roughly -250 mmHg. Pressures more negative than this would trigger alarms and stop the pump to safeguard the patient.
