High blood oxygen saturation despite pulmonary failure

You seem to have what I have. Did you get MIP MEP in PFT evaluated? Do you use bipap or cpap at night? You may have subclinical neuropathy like sfn and can get a skin biopsy.
You are describing the effects of diaphragm weakness, including rib tightness. Did you get cervical spine mri or phrenic nerve conduction? Was EMG normal? See a nvs specialist like breathenvs.com

ialogic,
It might help you to know about the hemoglobin oxygen dissociation curve. This is a graph which shows a standard blood oxygen saturation relating to normal oxygenation of tissues. It's called the dissociation curve because it measures factors which alter the bloods affinity for oxygen, either reducing it's capacity to carry oxygen or preventing the release of that oxygen by the blood. I've realised that I need to try to find if I've ever been tested for an enzyme called 2,3biphosphoglycerate mutase. It's one of many things which can increase the bloods affinity for oxygen. Although I've identified a wide range of factors which could have increased my bloods affinity for oxygen the problem has always been trying to find a way to prove that this has actually occurred. Finding, or obtaining, such a test would go a long way to convincing doctors that I have low oxygen usage by my tissues and muscles and that my high blood oxygen levels are abnormal.
