Brain blood flow: helmet vs nose-mouth mask during CPAP
Part of Lungs & breathing clinical trials.
This study compares how two types of breathing masks (a full-face helmet and a nose-and-mouth mask) affect blood flow in the brain while using a breathing support machine (CPAP). The results may help doctors choose a more comfortable mask for patients with sleep apnea or other breathing problems.

Other trials that look related to this one.
This study tests how well a specific breathing mask setup works in people who need noninvasive ventilation (breathing support without a breathing tube), especially during COPD flare-ups or certain kinds of breathing failure. It may help reduce complications related to the mask while supporting breathing for at least a day.
This trial studies whether CPAP treatment can improve blood pressure in people with obstructive sleep apnea. It aims to find out who benefits most from CPAP in terms of blood pressure control.
This trial looks at how CPAP (a breathing support device) affects the nose area in newborns and infants. If your baby is on CPAP and the doctor is checking for any nose issues, this study may help understand and improve 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 study looks at how sleep apnea affects your heart and blood vessels over time. It uses a sleep study and heart tests to see if certain measurements can predict heart health changes.
This trial compares two breathing devices—CPAP and high-flow nasal cannula—to see which works better for children with moderate to severe obstructive sleep apnea (a condition where breathing stops and starts during sleep). The study may help doctors choose the best treatment for your child.
