Could a daytime nap replace an overnight hospital stay for sleep apnea device tuning?
NCT ID NCT06559956
First seen Jun 24, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study compares two ways of adjusting a nerve stimulator implant (Inspire system) for obstructive sleep apnea. Currently, patients need an overnight sleep study to fine-tune the device. Researchers want to see if a daytime sleep study works just as well. The trial will enroll 110 adults who already have the implant.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- hypoglossal nerve stimulation (Inspire system)
- What this could lead to
- If successful, this could make it easier and more convenient for patients to get their sleep apnea device adjusted, reducing the need for overnight hospital stays.
- What could go wrong
- This is a small, early-stage study (110 people) comparing two methods of adjusting an existing device. It does not test a new treatment, so even if it works, it won't change the therapy itself.
