My mother has not been out of bed since March, now and again she has a bluish tint around the mouth, but not all the time, her hands are swollen but not her feet. Both hands and feet are cold to the touch. She is now getting weaker each day and hasn't eaten much since Tuesday and it's now Saturday, she is drinking water but mostly to take meds. Her breathing is shallow with 8 resps per min now and again her breathing stops for about 20 seconds. She sleeps most of the day and all of the night. She is 85yrs old. Is she now in the dying stage?
