Night to Night Variability in Sleep Disordered Breathing

STUDY BASICS

Have you been diagnosed with Obstructive Sleep Apnea (OSA), but are currently not being treated, or are waiting to start treatment? You may be eligible for a research study to improve our understanding of how sleep and breathing patterns vary from night to night among individuals with obstructive sleep apnea. Compensation is provided.

STUDY PURPOSE

This study seeks to better understand how sleep and breathing patterns change from night to night in people with obstructive sleep apnea. We are also examining how these nightly differences affect mood, energy, and daily functioning. Ultimately, our goal is to improve how we measure sleep apnea severity to better guide treatment and care.

COULD THIS STUDY BE RIGHT FOR YOU?

• Diagnosed with Obstructive Sleep Apnea (OSA), but are currently not being treated, or are waiting to start treatment
• Over the age of 18

WHAT PARTICIPANTS CAN EXPECT

Help Us Understand How Sleep Changes From Night to Night

Sleep, and sleep apnea, can vary from one night to the next. Our research study is looking at these nightly changes and how they may relate to how sleepy, tired, or alert people feel during the day.

The study begins with a 7-night screening phase that you complete at home. During this week, you will wear a small Sleep Image device on your finger while you sleep. You will also use an app on your phone, called m-Path, to answer brief questions during the day about things such as your sleepiness, fatigue, and mood.

Based on the results of the screening phase and other study criteria, you may be invited to continue to the second phase of the study, called ENNVISA.

The ENNVISA phase also takes place in your home and lasts for 7 nights. This phase provides us with much more detailed information about your sleep and therefore is more involved than the first week. Instead of wearing only a device on your finger, you will use sleep-monitoring equipment with sensors, patches, and wires that you will apply at home each night. You will continue answering brief questions during the day about how you are feeling.

By looking at sleep across multiple nights and comparing what happens during sleep with how people feel during the day, we hope to better understand night-to-night changes in sleep and sleep apnea that may be missed by studying only a single night.
