Sleep apnea and high blood pressure can affect cardiovascular health and brain function. Researchers at UCLA are studying whether a 12-week breathing training program may help improve blood pressure, brain activity, cardiovascular function, and overall well-being in adults who may have sleep apnea.

You may be eligible for this study if you meet the following criteria.

Inclusion Criteria:

• Suspected moderate-to-severe sleep apnea (e.g., snoring, daytime fatigue, higher body weight)
• Elevated blood pressure
• Are able to complete 2 in-person assessments at UCLA
• Have no major or unstable medical conditions
• Ages 18+

Screening

• Complete screening questionnaires.

• Complete an at-home sleep study to help determine whether you qualify.

First in-person visit

• Visit UCLA for an MRI scan of your brain and non-invasive health assessments, including blood pressure and heart activity measurements.

At-home breathing training

• Complete a breathing training program using a handheld device every day for 12 weeks.

• Complete questionnaires during the study.

• The daily breathing training and questionnaires should take approximately 5–10 minutes total.

Follow-up assessments

• Return to UCLA for a second in-person visit with assessments similar to those completed at your first visit.

• Complete a second at-home sleep study.

As a participant, you may receive up to $720 for completing all study-related activities. A complimentary Lyft or parking voucher can be provided to help with transportation to UCLA.

There is no cost for you to participate in our research study.
