I recently transferred to a clinic that allows their patient's art./ven. pressures to run up to 300. I was trained to never let it go above 240, so I lower the BFR if the press. hit 260. They however, will not lower the BFR unless it reaches 300. Any thoughts on this? I'm worried about damaging the pt.'s accesses.

Thanks for the feedback.

Hi,
On my unit we keep the blood flow at a level that the venous pressure does not exceed >200mgHg and the arterial pressure is not less than - 200mgHg. This is a useful method of recognising a decline in the function of the access (ie av fistula) and monitoring for anastamotic stenosis ( > than -200mg or a decline in pump speed acheived caused by sucking or total volume blood dialysed)or increased venous pressure with slower pump speeds and less neg arterial pressure (ie -80mgHg) can identify higher venous stenosis. If the prescribed pump speed is not being achieved the patient can be refered for scan and angioplasty early. I believe the reason you don't allow excessively high venous pressure or excessively negative arterial pressure is to prevent damage to red blood cells. I hope this is off some help.
