It was perceived by the pt that since the latest service of the pump (on (b)(6) 2014) had lost 'power', but as no alarms went off, she didn't think there was a functional problem.It was not after she developed the first pressure ulcer, while still using the system, she realized the quality was not good.With the right weight settings, she still developed a pressure ulcer.Besides the perception that the pump was not as powerful as before, it was noticed that it made a loud noise for several minutes, from time to time (for example at start-up), which was also confirmed by the driver, while he had installed the system.The pt has now used her spare pump, and this seem to function as it should be.Pressure ulcer, stage 2 was reported.
