Dialysis machine started having alarms while patient dialyzing.It started with concentrate type error, then had high venous pressure 155 and wanted a restart.Patient's venous pressures were within a normal range.A diaphragm neutral was performed.This seemed to correct things and the normal alarms you see when there's been a high pressure, like d1 flowmeter failure, diascan measurement failure and the alarms resolved only momentarily.Then alarm 116 dialyzer inlet pressure sensor alarm sounded as well as 134 temperature.From all the stopping an starting the dialyzer started to clot.I decided to take the patient off, no rinseback, new machine was set up.Patient was restarted on new machine.Patient had started to feel dizzy and was given 2l o2 nc.Patient felt better relatively quickly per herself.When trying to put this machine into a bleach at the end of the day it gave me alarm 65 dialysate line connection error.I re-seated the dialysate lines and got the same error code again.This machine was unable to be bleached and will have to be cultured before reuse.Biomed notified.
