Am looking for literature and research about lower limits of BP and still doing dialysis?
Do you have a cut off where you will not start a pt, even if they are asyptomatic? If you do start do you ultrafiltrate? I can't seem to find articles or reasearch.

You may want to check out the "Sodium Profiling" article on ANNA CE article site. Has the patient considered PD? Sometimes this is an option.

I think it depends on several issues. If the patient is an acute dialysis patient, hypotension should be addressed as not to further compromise restoration of kidney function returning. In a chronic setting if the patient's norm is hypotension and this is documented with no untoward effects during dialysis, I think it would be safe to dialyze. However I would use the mean arterial pressure as the measurement in this case as MAP below 60 causes a decrease in perfusion to vital organs. If dry weight has been established and fluid volume assessed then ultra filtration should be based upon that. If their pressure drops, then prehaps they are below dry weight and ultrafiltration should cease. As someone mentioned sodium variations may help to increase pressure and also lowering the dialysate temp helps according to the literature.
Thanks
