First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at 209 adults with moderate to severe sleep apnea to better understand how the condition affects the body. Instead of just counting breathing pauses, researchers used special measures like oxygen drops, heart rate changes, and sleep disruption. Participants used a CPAP machine for 12 weeks, and the team tracked changes in blood vessel health, blood pressure, and sleepiness. The goal was to find better ways to predict and prevent heart and brain problems linked to sleep apnea.
