Inspire Therapy: The Hypoglossal Nerve Implant
Inspire is a pacemaker-sized implant that senses each breath and gently stimulates the nerve controlling the tongue, keeping the airway open from the inside. It exists for one specific group: CPAP-intolerant patients with moderate-to-severe apnea who meet strict candidacy criteria.
Key takeaways
- A chest-implanted pulse generator detects breathing and delivers timed stimulation to the hypoglossal nerve, moving the tongue forward with each breath.
- Candidacy generally requires moderate-to-severe OSA, documented CPAP intolerance or failure, BMI under about 32–35, and favorable airway anatomy on endoscopy.
- Pivotal trial data showed roughly two-thirds reductions in AHI sustained at one year in selected patients, with high satisfaction.
- The system is activated about a month after surgery, titrated over following weeks, and switched on nightly with a small remote.
- It is surgery, with surgical risks and cost; a sleep-endoscopy exam and insurance review precede any implant decision.
What This Guide Covers
Inspire is a pacemaker-sized implant that senses each breath and gently stimulates the nerve controlling the tongue, keeping the airway open from the inside. It exists for one specific group: CPAP-intolerant patients with moderate-to-severe apnea who meet strict candidacy criteria. This guide walks you through what matters most, why it happens, and the practical steps with the best support behind them.
First, the foundation: a chest-implanted pulse generator detects breathing and delivers timed stimulation to the hypoglossal nerve, moving the tongue forward with each breath.
Next, the details: candidacy generally requires moderate-to-severe OSA, documented CPAP intolerance or failure, BMI under about 32–35, and favorable airway anatomy on endoscopy.
Then, the practical side: pivotal trial data showed roughly two-thirds reductions in AHI sustained at one year in selected patients, with high satisfaction.
Another angle worth knowing: the system is activated about a month after surgery, titrated over following weeks, and switched on nightly with a small remote.
Finally, the big picture: it is surgery, with surgical risks and cost; a sleep-endoscopy exam and insurance review precede any implant decision.

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.
