The difference between dialysis flow rate of 220ml/min and 250ml/min is not big, both are within the normal range of dialysis flow rate.
The blood flow of adults during hemodialysis is usually controlled between 200~300ml/min, and the blood flow of children is usually calculated at 3~5ml per kg of body weight, and the principle of dialysis blood flow is that the patient can tolerate it. The difference between a dialysis flow rate of 220 ml/min and 250 ml/min is the difference in the speed of the blood flow, the higher the flow rate the better the effect of removing toxins.
Generally speaking, when dialysis is required, a higher blood flow will result in a better removal of toxins and water. However, the blood flow needs to be adjusted according to the patient’s vascular access and the patient’s tolerance. If the blood flow rate is too low, it may lead to poorer effect of dialysis, and too high may cause some damage to the vascular access and cardiovascular system.
Dialysis flow rates of 220 ml/min and 250 ml/min are in the normal flow range, and patients can choose according to their own situation under the guidance of their doctors.
