Background: During haemodialysis, some patients experience intensification of symptoms of haemodialysis access‐induced distal ischaemia. Aim of this study is to compare the effects of two different regimens of arterial blood flow in patients with an arteriovenous access. Methods: A questionnaire identified 10 patients that subjectively experienced ischaemic symptoms during haemodialysis. Systolic blood pressure, heart rate, finger pressure (P dig ), finger temperature (T dig ), oxygen saturation and ischaemic scores were monitored during two different arterial blood flow dialysis sessions. Results: Before dialysis, P dig and T dig of the arteriovenous access hand were significantly lower compared with the other hand. Haemodialysis induced a drop of P dig in both hands. All changes in P dig occurred independent of the artificial kidney's blood flow level. Conclusion: Systemic hypotension following onset of haemodialysis further intensifies an already diminished hand perfusion. Measures preventing dialytic hypotension will likely attenuate symptoms associated with haemodialysis access‐induced distal ischaemia during haemodialysis.
