A comparison of intermittent vs continuous dialysis therapies

	CRRT	IHD
Time	24 hours	4–6 hours
Pump speed	100–180 mL/min	200–500 mL/min
Dialysis membrane	0.9 m2	1.1–2.1 m2
	High flux	+/– High flux
Dialysis flow rate	0–2 L/h	500–750 mL/min
Replacement fluid	1–3 L/h	None
Fluid removal	+100 mL/h to –500 mL/h	500–1000 mL/h

Abbreviations: CRRT, continuous renal replacement therapies; IHD, intermittent hemodialysis.
