What is the maximum allowable arterial pressure during dialysis treatment?

In dialysis treatment, especially during hemodialysis, monitoring arterial pressure is crucial for ensuring patient safety and effective treatment. The maximum allowable arterial pressure typically ensures that there is adequate blood flow through the dialysis machine while preventing potential complications such as vascular collapse or hemolysis.

A value of -240 mmHg is considered a maximum allowable negative arterial pressure. This level indicates that the pressure within the arterial line can drop to -240 mmHg during the treatment without risking significant adverse effects. Negative arterial pressure can occur due to various reasons, such as high vascular access resistance or kinks in the tubing, but there are limits to ensure patient safety.

Staying within this limit helps maintain adequate blood flow rates required for effective dialysis while minimizing the risk of complications. It reflects the balance between effective dialysis treatment and the patient's hemodynamic stability. Values outside this range may pose risks, affecting both the treatment's efficacy and the patient's health.
