It's not a NxStage requirement - it's your center being pissy. When I trained, my partner showed up for only a few sessions. As long as I could do the tech stuff, and he could deal with the emergencies, it didn't matter is he ws there for every session.See if you can get contact info for the NxStage rep who works with your center. They may be a better advocate for you - they want as many people on as possible!
I used a small walkie talkie set. Whoever was helping could be half a block away, and I could still get in touch with them so they could rush back in an emergency.
Hah - "Dailysis Patient Takes Control of Her Own Care" - that would be me... I don't post much lately, but I did dialyize alone for a year. I trained alone, and caused a bit of a kerfuffle when my unit closed and I was told that I could not dialyize alone.
I guess the requirements for a partner were given by a board at my facility. There were three doctors and three businessmen. It wasn't up to a head/charge nurse. I explained that I felt the decisions should come from the bottom up rather than top down, since each patient is different and their needs were different. My persistence that I didn't need all that much training for my partner finally paid off.
