@TreePerson @ Ben Howell
I have exactly the same questions. I have tried to talk to my GP about blood volume but he has no knowledge about how it can be measured. I have read of a Daxor machine but don't know if we have one in the UK, or any other way of measuring it. ( I think I did read something complicated once but cannot remember)
My GP actually said I would need to be cut and held upside down for the blood to run so it could be measured. I know- so insulting.
I have also asked about saline infusions and expanding blood volume. He told me I would need to be admitted to hospital if I were to have an infusion. He had no interest in whether this might help. No doubt cost would be expensive in a private hospital.
I have also become interested in the haemorrological properties of blood. Red blood cells should be pliable to get through narrow capillaries but ME patients' red blood cells might be stiff. ( Leslie Simpson)
Really thinking of help from saline though.
@ Ben Howell - please don't reply till you are feeling much better.
David Bell treated patients with IV saline. I think it's just an IV bag of isotonic saline. He even if I recall had one woman with a port, because she needed daily infusions to function.
