The control unit of the prue flow freaked out and has been giving odd alarms, tech agreed to send a new one. Our center rule is that water cultures must be drawn and cleared with each change in control unit. Labs are sent to a central Da Vita lab in Florida. I can't even send labs until Monday, takes about a week to clear. I counted up boxes and we would be short on bagged fluid to see us through from now until Friday or Saturday of next week. Over the past two months I've noticed that Nx Stage has not been replenishing the dwindling supply of reserve bagged fluid. Sending out just a few boxes a month. I called support, asking what we should do and why so few are being sent. Now they only allow ONE week of reserve, news to me. DH's has been running for nearly two years, we always had a two week reserve.I asked for a two week supply, support said they would have to call the center. Nurse calls, he talks about the high cost of shipping and patients using bags inappropriately (forgot to make batch, lazy, use bags instead of wasting part of a SAK, etc). If they limit the number of bagged fluid, it limits the temptation of using them. We are now only allowed one week of reserve. Thanks for the memo on that policy change. DaVita cutting costs yet again? How much reserve do you have?
