Testing air rebreathing during CPAP use
Part of Brain & nervous system, Lungs & breathing clinical trials.
This study checks how much air rebreathing (breathing in some of your own exhaled air) happens when you use a CPAP machine. It might help improve CPAP therapy for people with sleep apnea.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have moderate to severe sleep apnea with an AHI (a measure of breathing pauses) of more than 20.
- You currently use or have used a CPAP machine in the past.
- Your age is between 21 and 70.
- Your BMI is between 18 and 40.
- You do not have severe mouth breathing or any other sleep disorder besides sleep apnea.
- You do not need extra oxygen at night or have serious heart or lung disease.

This study helps doctors understand how to better adjust sleep apnea breathing machines by measuring your airway. You'll have a simple breathing test and overnight sleep study to help improve treatment.
This study looks at whether certain markers in sleep apnea patients can predict how well they will stick with CPAP (a mask that helps you breathe at night). If you're newly diagnosed and about to start CPAP, this could help personalize your care.
This study checks how ResMed CPAP mask systems work in real-life use for people with obstructive sleep apnea (OSA). It may help improve comfort, fit, and performance based on what patients experience over time.
This trial tests whether combining mouth and throat exercises with a CPAP machine (a device that gently pushes air to keep your airway open while you sleep) can help people with mild-to-moderate obstructive sleep apnea breathe better at night. The study aims to see if this combination approach is effective and safe for you.
This study tests a new wearable CPAP device for people with obstructive sleep apnea. It compares the device used with a mask system to standard treatment. You may be a good fit if you already use a ResMed AirFit N20 Medium mask and an APAP machine.
This study tests whether using continuous positive airway pressure (CPAP) can reduce acute COPD flare-ups in people who also have sleep apnea. It may help by improving breathing during sleep and lowering the chance of worsening lung symptoms.
