Dialysis Chills

For the first time Mom is actually cold. She is having some major chills while she is having her 4 hour dialysis session. I have piled tons of warm blankets on her and she seems to be falling sleep for periods of time. The room is dark and calm ... and for the most part the dialysis machine is not beeping like crazy. today is a big day for rehab as they plan to evaluate her. My fear is that the lack of sleep the last 2 nights and 4 hours of dialysis is not putting her in great shape for the evaluation. Praying that she will find the strength to get through the day.
