Is she happier with one to one company? Does she stop calling `help me` then? If so she is possibly unsure about where she is and might need reassurance. Sadly no one will be able to give her one to one reassurance 24/7 .
Will she watch television? does she like music?
Who knows what is going through her mind. It must be very hard for you.
Chrisss - my mum does that and yet says when asked that there is nothing wrong (after all obvious checks made) and doesn't know why she says it. This is, of course, the conversation on her more lucid days, but some reading I have done and conversations with the CH staff make me err to the theory that it is just a phrase that has got in a loop in her mind and the content isn't relevant to how she is. Mum has also gone through phases of "Is there anybody there?" (she does have limited vision) even mid conversation and / or when someone is holding her hand. Another was, "please can someone help me up" - this in the days when she was mobile but if you did try, she was indignant and wanted to know why you wanted her out of her chair!
But it is upsetting isn't it, especially that phrase as you feel there might be something and you are missing it. I try to look to see if she appears anxious or distressed in any other way and listen for the tone of her voice as that changes if she is actually uncomfortable or upset.
A lady in my husband's NH constantly called out "help me please". I expect if we were living with the dreadful confusion and other side effects of dementia we too would be calling out "help me". Nothing the Carers could offer would stop her plaintive cry - only sleep. She died and for a while I could still hear her calling down the corridor when I was visiting my husband - I was so used to it. However would add that it was easier to cope with than Ken who wandered around singing "Its a long road to Tipperary" out of tune - all day. Tried to get him to change to "Doing the Lambeth Walk" but that didn't last too long before he reverted to type!
She may well be on a 'loop' that doesn't necessarily mean anything. There was a lady in my mother's CH who was constantly saying, 'Can you help me, please?' When I first encountered it I said, yes, of course, what can I do? But she didn't know, couldn't answer, and did not actually seem distressed about anything.
Ages ago now but when FIL was in an EMI hospital for a while (before it was turned into expensive flats!) there was a man who called out, 'Where's Daise? Where's Daise?' endlessly, over and over. I suppose he meant his wife, poor man, but again I suspect it was a 'loop' since he never seemed upset or distressed.
My mum shouts constantly " where is everyone" if i leave her alone for a minute she starts shouting, i rush back in and ask whats wrong and she ses nothing, i wasnt shouting!!!! She does it in the night too and when we go in shes asleep. I think i find the shouting is the worsed of all and it really gets me down.
