preparation for circulation, the automatic test sequence has been completed and
the conductivity and pH testing are completed using the phoenix meter, this step
can take place - ANSWERS-The Hanson connectors (dialysate lines) can be
connected to the dialyzer
What position should the dialyzer be in during circulation (venous)? - ANSWERS-
Venous end straight up
