Frequently Asked Questions

What is being studied?

The study is testing a form of treatment for OSA called negative pressure using the aerSleep® II System (aerSleep II). The study sponsor is Sommetrics.​

How does it work?

The individual places the aerSleep II, a silicone oval collar with a small pump, on the front of the neck and under the chin area. Once in place, the small pump creates a forward pulling or suction of the neck tissues into the collar, which opens the airway. There are no tubes, masks or electricity required.

How long does the study last?

Your participation in the study would last about 28 weeks if you qualify and go through all of the study procedures.​

Will I be paid to be in the study?

Compensation is available to qualified participants. Study-related procedures and the study device will be provided at no cost.
