Testing airway pressure therapy to prevent pregnancy complications

This trial is testing whether continuous positive airway pressure (CPAP)—a machine that gently pushes air into your airway while you sleep—can prevent serious pregnancy complications like high blood pressure and gestational diabetes. Sleep apnea is a condition where breathing repeatedly stops and starts during sleep, and pregnant women with this condition appear to be at higher risk for these complications. Researchers want to see if treating sleep apnea during pregnancy can keep both you and your baby safer.

Pregnant women with untreated sleep apnea have higher rates of dangerously high blood pressure and gestational diabetes, which can harm both mother and baby. While this breathing machine is known to help non-pregnant people with sleep apnea, doctors don't yet know whether using it during pregnancy can actually prevent these serious complications.
