Summary

This study involved 65 adults with obstructive sleep apnea who had been using CPAP for at least 6 months. Participants stopped using CPAP for 2 weeks so researchers could measure changes in blood vessel function and heart rate control. The goal was to see if nighttime pulse wave patterns could predict how the body responds to stopping treatment. The study was terminated early, so results are limited.
