In addition disclosed are methods of using a dual-lumen needle in a two needle access for blood treatment is disclosed in which at least venous flow is provided through a dual-lumen needle with arterial flow just sufficient to provide air infiltration detection in the event of withdrawal of the dual-lumen needle.
