Hi! We are staffed pretty much the same way. Unless you are working days in my facility, you are the only nurse in the buildning. First, find out what your facility policy is. Second, make sure your aids know what to do. Our aids come and go pretty quickly, so I frequently explain to them what I would ask each of them do to do. I am very specific about this. We do a sort of quick "mock" code. I would stay with the resident, another aid would call 911 and the other would get the crash cart.
Our crash cart consist of suction, ambu bag and O2, so I am relying on CPR and how fast 911 services get notified and arrive.
