If it effect the flow and viscosity then how much it can effect in heart rate and blood pressure
heart rate is not affected by the flow, but the blood pressure could be.
Effect of hemodialysis on blood viscosity, blood flow rate, heart rate, and blood pressure.
Patients on hemodialysis have increased viscosity, that is multifactorial and can contribute to increased cardiovascular mortality in this group of patients with end stage renal disease (1).
Blood flow rate (BFR) through dialysis machine is one of the parameter of effective hemodialysis, and BFR 250 ml/min is associated with less effective dialysis, tissue ischemia, particularly the heart, and can lead to increased vascular events (2).
Dialysis is considered one of the strongest antihypertensive in patients who are undergoing hemodialysis. This why in hypertensive patients, antihypertensive drugs on the day of dialysis should not be given before dialysis session, because patients often develop hypotension during dialysis. Associated with hypotension, most of such patients develop tachycardia, but others have no effect, while a few may develop bradycardia(3). Hypotension is particularly more common in patients with ischemic heart disease and patients with diabetic complications (particularly autonomic neuropathy) with renal failure (4)
