Nursing literature reviewed physiology and suggested interventional strategies. Conclusions Recent papers allude to increasing evidence that repeated episodes of symptomatic as well as asymptomatic IDH contribute to adverse outcomes for the dialysis population. The lack of clarity in offering a succinct definition for IDH possibly hampers the effectiveness of preventative strategies. An individualised approach in ascribing acceptable blood pressure ranges for each patient - with recommended intervention levels - may go a long way to improving outcomes for haemodialysis patients.
