I'm taking care of an old lady diagnosed by vascular dementia.She also doing dialysis 3times a week 4hours every session.She's using her IJC on her to Dow dialysis.Everyday she loves to bath,for 1day she bath up to 6times from her day started up to night going to bed.For me troublesome everytime she wants to bath because i need to protect her IJC on her neck(small tube on her neck)not to get wet.Washing the hair on her bed,wash carefully and cover it properly.For a 75 years old lady diagnosed by vascular dementia is it good for her to bath all the time she wants?
