Summary

This study looks at whether a CPAP machine, often used for sleep apnea, can safely lower high blood pressure that happens when people with autonomic failure lie down. About 12 adults with this condition will try CPAP while researchers measure changes in their blood pressure and nighttime urine output. The goal is to find a simple, non-drug way to manage this common and tricky problem.
