Here are some of my "Carrie Moments" and Nightmares...I never was able to use blunts on my arterial site, I always had to use a sharp, and would often spend so much time spinning needles that I would clot.The time I didn't tape my return very well, and the needle flew out and sprayed my little apartment with blood like a paint gun.The time I filled a saline bag with blood (ok, it wasn't filled but it seemed like it)The time my pureflow flooded my apartment.The time that just as I got on dialysis in the summer, the machine quit because it was too hot in the house to do a run.
