Inspire Hypoglossal Nerve Stimulation: Implant Guide
For CPAP-intolerant patients with the right anatomy, a small implanted device stimulates the tongue to keep the airway open with every breath. How Inspire works, who qualifies, and what the surgery involves.
Key takeaways
- The device senses breathing and stimulates the hypoglossal nerve, timing tongue muscle activation to keep the airway open.
- Candidates must have moderate-to-severe OSA, CPAP intolerance, a BMI typically under 32–35, and non-circular airway collapse on drug-induced sleep endoscopy.
- Implantation is an outpatient surgery of about 90 minutes under general anesthesia.
- Studies show roughly a 50–70% reduction in AHI and significant improvements in sleepiness and quality of life.
- The device is activated by the patient each night with a small remote and includes a sleep mode that starts automatically.
What This Guide Covers
For CPAP-intolerant patients with the right anatomy, a small implanted device stimulates the tongue to keep the airway open with every breath. How Inspire works, who qualifies, and what the surgery involves. This guide walks you through what matters most, why it happens, and the practical steps with the best support behind them.
First, the foundation: the device senses breathing and stimulates the hypoglossal nerve, timing tongue muscle activation to keep the airway open.
Next, the details: candidates must have moderate-to-severe OSA, CPAP intolerance, a BMI typically under 32–35, and non-circular airway collapse on drug-induced sleep endoscopy.
Then, the practical side: implantation is an outpatient surgery of about 90 minutes under general anesthesia.
Another angle worth knowing: studies show roughly a 50–70% reduction in AHI and significant improvements in sleepiness and quality of life.
Finally, the big picture: the device is activated by the patient each night with a small remote and includes a sleep mode that starts automatically.

How long until I see improvement?
Most of the strategies in this guide start showing effect within one to two weeks of consistent practice. Supplement- and device-based approaches vary more, so track your nights in a simple sleep diary and judge by weekly trends rather than single nights.
When should I see a doctor?
If the problem lasts more than a few weeks, disrupts your daytime functioning, or comes with warning signs such as breathing pauses, gasping during sleep, chest discomfort, or severe daytime sleepiness, it is time to consult a qualified healthcare professional rather than self-treating.
