My wife's pain was based on fill levels. She was 80% tidal with a 1,900 ml fill on 8 cycles per night. She started good on her kinetics although she did dread the treatments. Back at the end of last year her kinetics fell below minimum and her nurse said she needed to start getting more fluid in the fill. I protested and said no, there must be another way. As it ended up the nurse crunched the numbers and came up with a new program using tidal 50% with 18 cycles in the same 9 hour treatment time. We were skeptical that 15 minute cycles would work, but the first kinetics test showed 30% improvement over her previous best test, (which her doc and PD nurse were thrilled with). In addition we are using more fluid but with the additional cycles she actually doesn't have the extremes in filling that she used to have. Her treatment is very comfortable and she is happy. Bottom line this program was developed by a different nurse at the dialysis facility. Not the one who she is assigned to. The answer sometimes in my opinion is telling your nurse that this program may need to change to see if they can minimize the pain. Some nurses aren't willing to do the work needed to see if there are alternate ways to program the cycler, which will result in the same or better results. Jack
