OBSTRUCTIVE SLEEP APNEA OF ADULT

This study looks at whether using a CPAP machine during pregnancy can reduce the chance of developing high blood pressure disorders like preeclampsia. About 1,500 pregnant women with mild to moderate sleep apnea will be randomly assigned to use CPAP or not. The goal is to see if …

This study tests whether taking melatonin before bed for 30 days can help adults with obstructive sleep apnea and insomnia sleep through the night and restore a healthy nighttime blood pressure dip. About 50 participants will take 3 mg of melatonin nightly. The goal is to see if …

This study tests a new device that uses freezing (cryotherapy) to treat obstructive sleep apnea in 25 adults who cannot use standard treatments like CPAP machines. The goal is to see if the procedure is safe and can reduce breathing pauses during sleep. Participants will be follo…

This study looks at whether continuing GLP-1 agonist drugs (like Ozempic or Wegovy) after weight-loss surgery helps people lose more weight and control blood sugar better than stopping them. About 150 adults with severe obesity will be randomly assigned to either keep taking the …

This study tests whether a special breathing exercise program (inspiratory muscle training) can reduce daytime sleepiness in adults with obstructive sleep apnea who already use a CPAP machine. About 58 participants will be randomly assigned to add the breathing exercises or conti…

This study looks at how changes in brain blood flow affect breathing control during sleep in healthy adults. Researchers will use mild oxygen changes and a placebo to measure responses. The goal is to better understand conditions like sleep apnea, not to treat them directly.

This study looks at whether taking atorvastatin (a statin) for 4 weeks can lower inflammation and blood clotting risks in adults with obstructive sleep apnea who are already using CPAP therapy. Researchers will measure specific markers in the blood and cells. About 110 newly diag…

This study looks at whether checking dental patients for undiagnosed sleep apnea before surgery under anesthesia can help predict and prevent breathing problems after the procedure. Researchers will screen 240 adults using standard questionnaires and refer high-risk patients for …

This study looks at how sleep apnea changes fat tissue and whether those changes increase the risk of heart disease. Researchers will take small fat samples from the belly and thigh of 120 adults with sleep apnea. The goal is to understand the link between sleep apnea, fat tissue…
