Let me try to answer this as a newbie:Thank you M3R. This looks like it is doable. I finally got my hands on some manuals, and this is what I read:pp 8-2 NxStage System One (NSO) manual, 100-120V, 600VA (200 VA cycler, 400VA AC outlet)pp 10-2 Pureflow User guide, 100-120V, 400VAthe bag warmer on the NxStage System One is separate from System One and looks like it is 5A. You will likely to be using the warmer on the Pureflow or the bag warmer, but not both at the same time, so the draw would be about 600VA or approximately 600W.If you get the APC Smart UPS 1500 http://www.apc.com/products/resource/include/techspec_index.cfm?base_sku=SUA1500&total_watts=50You may be able to power the NxStage System One with the bag warmer or the Pureflow at a draw of 600VA for about 18 minutes, may be a lot longer if you can shut off the warmer (it is also unlikely the warmer will be constantly drawing 400VA all of that 18 minutes). Certainly you should be able to start a manual generator in that time or hopefully the utility can restore the power in that time. I don't know enough about the NSO to know if you can trigger an early termination and return of blood by the emergent rinseback procedure.pp 8-2 NxStage System One (NSO) manual, 100-120V, 600VA (200 VA cycler, 400VA AC outlet)pp 10-2 Pureflow User guide, 100-120V, 400VAMost of the power is actually used by Pureflow warmer in the standby mode.Assuming your Pureflow is turned on 24hr x 6 days and that the warmer heating element comes on about 20% of the time (depending on room temperature), that is about 30 hours a week or 30 hr x 400 W = 12000 W-hr. In addition the NSO cycler comes on about 5 hr x 6 days x 200W = 6000 W-hr.Approximately you will be using ~78 kW-hr additional power per month. At 10 cents per kW-hr, that would be about $8 in additional expense in electricity per month, which is about that of a 12 cu ft refrigerator.Last edited by greg10; 09-13-2010 at 09:21 PM."
I know I can get this answered at my center by physically looking at a machine, but the question is intriguing to me right now LOL.If someone can read me the "watt rating" on the nameplate of their NxStage?Why do I want this info? I travel sometimes with my fifth wheel RV, and I want to see if my "quiet" inverter system (converts 12 volts DC battery power to "regular" 120 volts AC(regular here in the US anyway LOL)) system has enough capacity as is to handle hours and hours of the NxStage machine running, should I go to that modality. Yeah, I could fire up my generator, but I can't always run the generator at night due to noise restrictions (especially when camping). The inverter system runs off storage batteries and is completely quiet on the outside.Ok, this is not something that is critical to know right now, just wondering if anybody knows.---Dan
@ DannyBoy - thought you would enjoy reading these articles by Georgia Harper, one of the earliest patients taking full advantage of RV dialysis. Some of the issues he addresses might still apply today - even with the convenience of portable NxStage machines.http://www.globaldialysis.com/your-stories/108340000-rv-dialysis-a-dream-realized-and-a-dream-threatened.htmlhttp://www.cc.utah.edu/~cla6202/GeoH.htm
