Does this happen intermittently or every night? I assume you’ve talked with your home training nurse. Have you talked with Baxter’s clinical nurse? Could you be constipated? Could fibrin be blocking some of the holes in the catheter? Could your catheter have moved away from the lowest point in your peritoneal cavity? Someone on this thread started in 2007 suggested that a low battery could produce this alarm. Seems like your nurse, the Baxter nurse, or their technical support could help if you know for sure aren’t constipated, the catheter is not plugged with fibrin or it’s hasn’t moved out of the correct location. Here’s the other thread. NOTE: the link to the job aid for Baxter that I posted doesn’t seem to work and I haven’t been able to locate it yet.
