What Is Inspire Sleep Therapy?
Inspire Sleep Therapy is an implantable device that treats obstructive sleep apnea by gently stimulating a nerve that controls the muscles of the upper airway. Unlike CPAP, which uses pressurized air pushed through a mask, Inspire works from inside the body to keep the airway open during sleep.
According to the American Academy of Sleep Medicine, at least 25 million American adults have obstructive sleep apnea, and many cannot tolerate or stick with CPAP therapy. For these patients, Inspire offers a different path to restful sleep and lower long-term health risks.
How Does Inspire Sleep Work?
If you have been wondering how Inspire sleep works, the concept is simpler than most patients expect. The system uses three small components placed under the skin during an outpatient procedure, and a patient-controlled remote turns the therapy on at night.
Components of the Inspire Implant
The Inspire system includes:
- A small generator (battery) placed under the skin of the upper chest, similar to a pacemaker
- A breathing sensor lead that detects the patient's natural breathing pattern
- A stimulation lead placed near the hypoglossal nerve, which controls tongue movement
What Happens During Sleep
When the patient turns Inspire on with the handheld remote and goes to bed:
- The breathing sensor monitors each breath in real time.
- With every inhalation, the device sends a gentle electrical pulse to the hypoglossal nerve.
- That signal moves the tongue and surrounding airway muscles slightly forward.
- The airway stays open, so air flows naturally and the patient continues to breathe normally.
There is no mask, no hose, and no pressure on the face. Most patients describe the sensation as a mild tingling or tongue movement that quickly fades from awareness.
Inspire vs. CPAP: How Are They Different?
CPAP remains the gold-standard first-line treatment for obstructive sleep apnea, but it does not work for everyone. Many patients find the mask uncomfortable, claustrophobic, or hard to use consistently. The team at Altoona Lung Specialists notes that a significant percentage of patients prescribed CPAP do not stay on it long term, which leaves their sleep apnea untreated.
Inspire offers an alternative that some patients prefer once CPAP has been tried.
| Feature | CPAP | Inspire Sleep Therapy |
|---|---|---|
| How it works | Blows pressurized air through a mask to hold the airway open | Stimulates the hypoglossal nerve to move the tongue forward |
| Equipment worn at night | Mask, hose, headgear, and bedside machine | Handheld remote, no external equipment |
| Travel | Requires bringing the machine and supplies | No equipment to pack |
| Power | Needs an electrical outlet | Battery is implanted, no plug needed |
| Best fit | Most patients with OSA, first-line therapy | Adults with moderate to severe OSA who cannot use or benefit from CPAP |
| Procedure | Non-invasive, no surgery | Same-day outpatient procedure |
Neither device is 'better' in every situation. The right choice depends on the patient's anatomy, severity of OSA, body weight, and how well they tolerate CPAP.
Who Qualifies for Inspire Therapy for Sleep Apnea?
Inspire therapy for sleep apnea is not for everyone. According to the eligibility criteria outlined by Altoona Lung Specialists and the manufacturer, candidates are typically adults who:
- Are over the age of 18
- Have been diagnosed with moderate to severe obstructive sleep apnea, defined as an Apnea-Hypopnea Index (AHI) between 15 and 65
- Are unable to use or do not get consistent benefit from CPAP therapy
- Are not significantly overweight (BMI guidelines apply)
- Do not have certain anatomical features that limit the device's effectiveness
A sleep study and a brief in-office evaluation, including a drug-induced sleep endoscopy (DISE) in some cases, help determine whether Inspire is a good fit. Altoona Lung Specialists guides patients through each step of this workup at the Sleep Disorder Network.
What Happens During the Inspire Implant Procedure for Sleep Apnea
The Inspire implant for sleep apnea is placed during a same-day outpatient procedure. Most patients return home the same day and can resume non-strenuous activities within a few days. Here is what the experience typically looks like:
- Before the procedure: Patients meet with the pulmonary and surgical team for a thorough evaluation, complete a sleep study, and review imaging or DISE results.
- The procedure: A surgeon places the generator and leads through two or three small incisions in the upper chest and neck. The procedure usually takes a couple of hours.
- Recovery: Patients usually go home the same day. Over-the-counter pain medication is typically enough for the first few days.
- Activation: About a month after surgery, when healing is complete, the device is turned on and customized to the patient's needs during a brief office visit.
- Follow-up: The team adjusts settings over the following weeks and months to optimize comfort and effectiveness, often paired with another sleep study to confirm results.
What Patients in Altoona Can Expect From Their Inspire Therapy Journey
Altoona Lung Specialists is part of the Lung Disease Center of Central PA and offers comprehensive evaluation and follow-up care for Inspire therapy for obstructive sleep apnea. Patients benefit from:
- An on-site board-certified sleep physician
- In-house diagnostic and titration sleep testing
- A coordinated team that supports patients before, during, and after the procedure
- Ongoing optimization of the Inspire system to fit each patient's needs
For patients in Blair, Bedford, Centre, and surrounding counties, this means receiving sleep apnea care close to home rather than traveling out of the region.
The Inspire system was FDA-approved in 2014. As reported by Altoona Lung Specialists, one-year results from the STAR clinical trial were published in the New England Journal of Medicine, and follow-up data over five years showed sustained reductions in sleep apnea events and improvements in quality of life. According to the practice's Inspire Therapy Basics page, real-world outcomes include a 79% reduction in sleep apnea events and 90% of bed partners reporting no snoring or only soft snoring.

Frequently Asked Questions
How does Inspire sleep therapy work in the simplest terms?
Inspire is a small implanted device that monitors your breathing during sleep. With every inhalation, it sends a gentle electrical signal to the nerve that controls your tongue, moving it slightly forward so your airway stays open. There is no mask or hose, just a remote you click before bed.
Is Inspire sleep therapy better than CPAP?
It depends on the patient. CPAP is highly effective when used consistently and remains the first-line therapy for most people with obstructive sleep apnea. Inspire is generally considered for adults with moderate to severe OSA who cannot tolerate or get enough benefit from CPAP and who meet specific eligibility criteria.
How do I know if I qualify for an Inspire implant for sleep apnea?
You may qualify if you are over 18, have moderate to severe OSA (AHI between 15 and 65), have tried CPAP without success, and are not significantly overweight. A pulmonologist will review your sleep study, medical history, and airway anatomy to determine whether Inspire is right for you.
Is the Inspire procedure painful or risky?
The Inspire procedure is performed on an outpatient basis through two or three small incisions in the upper chest and neck. Most patients go home the same day, use over-the-counter pain medicine for a few days, and return to non-strenuous activities within a week. As with any procedure, the surgical team will review the specific risks and what to expect with you before deciding to move forward.
What does Inspire therapy for obstructive sleep apnea feel like at night?
Most patients describe the sensation as a mild tingling or gentle tongue movement that quickly fades as they fall asleep. There is no mask pressure, no noise, and no airflow against the face. The handheld remote lets patients turn the therapy on at bedtime, pause it during the night if needed, and turn it off in the morning.
