Who May Be a Candidate for Inspire® When CPAP Is Not Working?

What Is Inspire^® Therapy?

Inspire^® therapy is an implantable treatment for certain people with moderate to severe obstructive sleep apnea.

Unlike CPAP, Inspire^® does not use a mask or hose. The system monitors your breathing while you sleep and delivers mild stimulation to the hypoglossal nerve, which controls tongue and upper-airway movement. This stimulation helps move the tongue forward so the airway is less likely to become obstructed.

After the implanted device has been activated and programmed, you use a handheld remote to turn therapy on before sleeping and off after waking.

Why Does CPAP Not Work for Everyone?

CPAP uses pressurized air to keep the airway open during sleep. It can be highly effective when used as prescribed, but some patients have difficulty tolerating it consistently.

Common challenges include:

• An uncomfortable or poorly fitting mask
• Air leaking around the mask
• Nasal dryness, congestion, or irritation
• Dry mouth
• Difficulty tolerating air pressure
• Claustrophobia or anxiety while wearing the mask
• Trouble falling or staying asleep
• Unintentionally removing the mask during sleep

Before considering an implanted treatment, your sleep medicine or ENT provider may recommend adjusting the mask, pressure settings, humidification, or treatment for nasal obstruction. If those changes do not help, an evaluation for another therapy may be reasonable.

Who May Qualify for Inspire?

CPAP intolerance by itself does not establish eligibility for Inspire^®. The treatment is designed for a particular group of patients, and candidacy depends on sleep-study results, airway anatomy, medical history, and other clinical factors.

Under current FDA-approved labeling, an adult may be considered for Inspire^® when the following conditions are met:

• The patient is at least 18 years old.
• A sleep study confirms moderate to severe obstructive sleep apnea.
• The apnea-hypopnea index, or AHI, is between 15 and 100 events per hour.
• Positive airway pressure therapy has not provided adequate benefit or cannot be used consistently.
• Central and mixed apneas account for less than 25% of the total AHI.
• An airway evaluation does not show complete concentric collapse at the level of the soft palate.
• The patient is healthy enough to undergo the implantation procedure.

The manufacturer notes that Inspire^® has not been studied in a significant number of patients with a body mass index above 40, so outcomes and risks in that population are less certain. Insurance plans may use different or narrower coverage requirements, including lower BMI or AHI limits. Medical candidacy and insurance authorization are separate determinations.

You can review the current indications, limitations, and safety information on the official Inspire^® safety-information page.

What Happens During an Inspire Evaluation?

An Inspire evaluation is designed to determine whether the treatment is likely to address the type of airway obstruction causing your sleep apnea.

Your provider may:

• Review your current or previous sleep study
• Confirm that the condition is primarily obstructive rather than central sleep apnea
• Discuss how long you used CPAP and why it was unsuccessful
• Review attempts to improve CPAP comfort or effectiveness
• Examine your nose, throat, and upper airway
• Review your medical history, medications, and prior procedures
• Discuss the potential benefits, limitations, and surgical risks

Your provider will also determine whether a newer sleep study is needed. Testing and documentation requirements can vary according to clinical circumstances and insurance coverage.

Why Is Drug-Induced Sleep Endoscopy Important?

Many patients being evaluated for Inspire undergo drug-induced sleep endoscopy, commonly called DISE.

During DISE, medication places you in a sleep-like state while an ENT physician examines the upper airway with a small flexible camera. This allows the physician to observe where and how the airway collapses during sleep.

Inspire^® is generally not indicated when the soft palate demonstrates complete concentric collapse. DISE helps identify this pattern and can reveal other anatomical factors that may influence which sleep apnea treatment is most appropriate.

Who May Not Be a Candidate?

Inspire^® may not be appropriate when:

• Sleep apnea is mild.
• Central and mixed apneas make up 25% or more of the total AHI.
• DISE shows complete concentric collapse at the soft palate.
• A person cannot safely undergo surgery.
• Certain anatomical or neurological conditions would prevent the therapy from working as intended.
• The patient cannot operate the remote or receive appropriate help using it.
• Another treatment is more appropriate based on the cause of the obstruction.

Other factors, including pregnancy, implanted devices, future MRI needs, and specific medical conditions, may also influence the decision. These considerations should be reviewed individually with the treating physician.

What Are the Potential Advantages of Inspire^®?

For appropriately selected patients, potential advantages include:

• No mask or hose during sleep
• No pressurized air
• Treatment that operates while the patient sleeps
• A handheld remote that controls the therapy
• Adjustable stimulation settings
• An alternative for some patients unable to use CPAP consistently

Inspire^® may reduce obstructive sleep apnea events and improve symptoms in appropriately selected patients, but results vary. It does not work equally well for everyone and cannot guarantee that every apnea event, episode of snoring, or daytime symptom will resolve.

Does Inspire Cure Obstructive Sleep Apnea?

Inspire treats obstructive sleep apnea while the therapy is active, but it is not considered a cure.

The device requires ongoing monitoring, programming, and follow-up care. A follow-up sleep study may be used to assess how effectively the therapy is controlling breathing events. Patients should continue seeing their sleep medicine or ENT provider even if their symptoms improve.

Changes in weight, health, medications, or airway anatomy may also affect sleep apnea and treatment results over time.

What Are the Risks and Limitations?

Inspire^® requires surgery, so it carries risks associated with implantation and anesthesia. Potential complications may include:

• Pain, bruising, or swelling
• Infection
• Bleeding
• Scarring
• Temporary tongue weakness
• Discomfort from stimulation
• Tongue soreness or abrasion
• Dry mouth
• Device-related discomfort
• The need for additional programming or another procedure

The implanted battery will eventually need to be replaced. Patients must also follow device-specific precautions involving certain medical procedures and MRI examinations.

Your provider should review the expected benefits, potential risks, alternatives, and device requirements before you decide whether to proceed.

What Is Recovery Like?

Inspire^® is generally implanted during an outpatient procedure, although individual circumstances vary. Patients commonly return home the same day with instructions for incision care and temporary activity restrictions.

The system is not usually activated immediately. The incisions are allowed to heal, and the device is then activated and programmed at a follow-up appointment several weeks later. Settings may be gradually adjusted to balance effectiveness and comfort.

Follow-up testing may be recommended after the patient has had time to become comfortable with the therapy.

What Other Options Are Available When CPAP Is Difficult to Use?

Inspire^® is only one possible alternative. Depending on the cause and severity of your sleep apnea, other options may include:

• Trying a different CPAP mask
• Adjusting pressure or humidification settings
• Treating nasal obstruction that interferes with CPAP use
• Oral appliance therapy
• Positional therapy
• Weight management when medically appropriate
• Other airway procedures based on individual anatomy

An evaluation should consider these options rather than assuming an implanted device is the only next step.

When Should You Discuss Inspire^® With an ENT?

Consider scheduling an evaluation if you have confirmed moderate to severe obstructive sleep apnea and cannot use CPAP consistently despite efforts to improve comfort and effectiveness.

An evaluation may also be helpful if:

• CPAP remains intolerable after mask or setting adjustments.
• You continue experiencing sleep apnea symptoms because you cannot use CPAP regularly.
• You want to understand whether your sleep-study results fall within Inspire’s indications.
• You want to compare Inspire^® with oral appliances, CPAP optimization, or other treatments.

Learning what to expect from an ENT and sleep apnea evaluation in Foley can help you prepare for the discussion.

Find Out Whether Inspire May Be an Option

Not everyone who struggles with CPAP will qualify for Inspire. Candidacy depends on the type and severity of sleep apnea, airway anatomy, medical history, and findings from a comprehensive evaluation.

Schedule an appointment with ENT Centers of Excellence to discuss your experience with CPAP and determine whether Inspire^® or another obstructive sleep apnea treatment may be appropriate.
