I was just setting up my machine when at the last minute I got a red 90 alarm during prime. Spoke with people at nxstage…they said that the saline might need to be warmed before prime? Anyone else had this? I have just put on a new kidney…hoping it primes o.k. without any red 90’s…I did not warm up the saline as I got this information after I had already put the new one in.
