Hospitalized copd pt was on vapotherm precision flow device when nursing staff discovered the pt was hypoxic with associated altered mental status requiring immediate intervention.It was noted by nursing staff responding to the code that the vapotherm had shut off.The device wasn't beeping prior to the event (as per discussion with the nurse who was in the room prior to the event and the family who had also been present in the room before and during the event).The machine would not immediately turn back on.The machine was taken out of service and turned back on.It appeared to be working again.We inspected the wall plugs and they were functioning properly.We ran the machine again to try to shut it off and it seemed to be operating fine.We unplugged it and it sounded an audible alert for sometime before shutting down.We do not know why this unit shutdown with no warning while in use on a pt.Fda safety report id# (b)(4).
