Does increased carbon dioxide (CO2) make patients with Neurogenic Orthostatic Hypotension feel better?

Summary

We are studying if increased carbon dioxide (CO2) can increase blood pressure and reduce symptoms in patients with Neurogenic Orthostatic Hypotension (NOH) and healthy volunteers. Participants will perform four active stand tests under different CO2 levels. We will monitor blood pressure, heart rate, and brain blood flow to determine which intervention is the most effective in minimizing symptoms and improving blood pressure. We will also take pictures of the blood vessels in the eye to better understand changes happening close to the brain
