A warm welcome to the forum.
I’m really sorry to hear about your dad’s low oxygen levels. Some people with Parkinson’s may experience problems with low blood pressure which can affect oxygen levels in the body. However, I think it would be worth speaking to one of our advisers via our helpline service for their expert advise on this. If you give them a call on 0808 800 0303 they can arrange for a Parkinson’s nurse to contact you within 24 hours or they can simply provide you with more information and support.
I hope you find the above information helpful.
