All day today I was worried about doing my husband treatment because we are in the middle of what seems like the storm of the century. At around 9 PM we started his treatment (we have only been home for a little over a week). At 10:40 sure enough what I was worried about happened, the power went out, but only for a second. I was all prepared with a flashlight and anything else, just in case.... but I was not prepared for what happened when the power came back on. When we were in training they kept saying if the power goes out for more then two minutes manually rinse back his blood. Well the power came back on, so did the machine but it did not start running again. I was like the mad hatter rushing around, pushing stop, treatment, reading through the manuals and I could find nothing on what to do. All I seen was how to do a manual rinse back if the power didn't come back. So after like a minute or two of freaking out I decided to just do a manual rinse back, which I did with no problem even though the machine start making the loudest noise ever as soon as I opened the cycler door (sounded like the fan was blowing up). After I did the rinse back and pulled his needles and re-set the cycler, I called Nxstage and was informed that if the power goes out and comes back on, sense the cycler was set to on, you need to turn the power off to the cycler and turn it back on, then you will get a yellow 40, then you can hit treatment again. No where in the manual could I find this, it is probably in there somewhere, but I couldn't find it. Wanted to share this in case anyone else could use this information.
