What is the maximum allowable pre-pump arterial pressure according to DaVita policy?

The maximum allowable pre-pump arterial pressure according to DaVita policy is -260 mmHg. Maintaining proper pressure levels in dialysis systems is crucial for ensuring the patient's safety and the efficiency of the dialysis process. This value is set to prevent complications that can arise from excessively negative pressures, such as the risk of collapsing the access site or causing hemolysis of red blood cells due to excessive suction.

The choice of -260 mmHg reflects a balance between the need for adequate blood flow during dialysis and the management of patient safety. Staying within this limit ensures that the system operates safely, allowing for effective removal of toxins and excess fluids while mitigating any potential risks associated with pressures that are too low. Understanding this limit is essential for healthcare professionals involved in dialysis procedures, as it directly impacts patient care and outcomes.
