Did you know you can load a cartridge in the NxStage System One and turn it off. This can save some set up time for that late night at the movie or a good nap before a treatment.
Kdrpiper, you are right it does clamp the blood line in several places, but you are wrong in the rest of your comments. Everytime a balance check happens, the lines are clamped. If you look at your cartride after a treatment, you will find kinks in the same place as stopping the machine at 23. Not to mention that it was NxStage that taught me this trick.
