My dad is in the late stages of PD. He is in and out of hospital at the minute which is very stressful. He has a care plan in place now so he can be kept at his care home. Each time he goes into hospital it is because of low oxygen levels, he has an X-ray and this shows nothing. They give him iv antibiotics and oxygen and ship him home. A few days later the same happens again. I am really just wanting to know if low oxygen levels are a normal part of late stage PD? Also what can we do to help him with this? I have asked the doc to prescribe him oxygen as this seems to help him. Can anyone offer any other advice?
