My mother has Alzhimer's and is 90 years old She was very, very, very tired today (mostly every day) when we got home she feel asleep in her chair when I tried to wake her she was clamy, both face, head and hands, not very responsive, and her SYS was-61 her DIA- was 40 and her PULSE was 55. I had to carry her into her bed. She is sleeping now. Should I just keep an eye on her the rest of the night, or call 911 right now?
