Qualification Guidelines

Inspire Candidate Qualification

Understand the medical criteria, requirements, and assessment process to determine if you're a candidate for Inspire therapy.

Key Requirement

Only candidates who have failed or cannot tolerate CPAP therapy after adequate trial are eligible for Inspire therapy evaluation.

Primary Qualification Criteria

All of these criteria must be met for Inspire therapy candidacy. Your sleep specialist will evaluate each requirement during your consultation.

Required

Sleep Apnea Severity

Documented moderate to severe obstructive sleep apnea diagnosis

AHI between 15-65 events per hour
Required

Age Requirement

Must be adult patient with mature airway anatomy

18 years of age or older
Required

CPAP Treatment History

Unable to use or benefit from CPAP therapy after adequate trial

CPAP failure or intolerance documented
Required

Body Mass Index (BMI)

Weight requirement for optimal therapy effectiveness

BMI of 35 kg/m² or less
Required

Airway Anatomy

Suitable upper airway collapse pattern confirmed by DISE

No complete concentric collapse at soft palate level

Treatment Commitment

Willing to use device nightly and follow up with physician

Commitment to nightly use and regular follow-up

Detailed Requirements Breakdown

Sleep Study Requirements

AHI Criteria (Required)

  • AHI ≥15 events per hour (moderate sleep apnea)
  • AHI ≤65 events per hour (upper limit for effectiveness)
  • Predominantly obstructive events (not central)

Additional Sleep Metrics

  • Sleep efficiency and architecture assessment
  • Oxygen desaturation index evaluation
  • Arousal index and sleep fragmentation review

CPAP Failure Documentation

Inadequate CPAP Response

  • Residual AHI >10 despite optimal CPAP pressure
  • Persistent symptoms despite CPAP compliance
  • Central apneas emerging on CPAP therapy

CPAP Intolerance

  • Usage <4 hours per night for 5+ nights per week
  • Claustrophobia or mask intolerance
  • Skin irritation or pressure sores from mask

Drug-Induced Sleep Endoscopy (DISE)

DISE is a required procedure to evaluate your upper airway anatomy and collapse patterns while you're in a sleep-like state. This determines anatomical suitability for Inspire therapy.

Favorable DISE Findings

  • Lateral or anterior-posterior collapse at soft palate
  • Base of tongue or lateral pharyngeal wall collapse
  • Epiglottic collapse patterns

Unfavorable DISE Findings

  • Complete concentric collapse at soft palate level
  • Severe multilevel collapse patterns
  • Fixed anatomical obstructions

Contraindications & Exclusions

These conditions may prevent candidacy for Inspire therapy or require careful evaluation by your sleep specialist.

Absolute Contraindications

Central or mixed sleep apnea

Inspire only treats obstructive sleep apnea

Complete concentric collapse at soft palate

Anatomy not suitable for therapy effectiveness

BMI greater than 35 kg/m²

Reduced effectiveness with higher BMI

Relative Contraindications

Active psychiatric disease preventing compliance

Requires nightly device use and follow-up

Life expectancy less than therapy benefit period

Cost-benefit considerations

Pregnancy

Safety not established during pregnancy

Candidacy Assessment Process

1

Initial Consultation

Sleep specialist reviews medical history, sleep study results, CPAP trial documentation, and performs physical examination focusing on upper airway anatomy.

2

DISE Procedure

Drug-induced sleep endoscopy performed to evaluate airway collapse patterns and determine anatomical suitability for hypoglossal nerve stimulation.

3

Multidisciplinary Review

Sleep medicine team reviews all findings, discusses candidacy with patient, and provides comprehensive education about therapy expectations and outcomes.

4

Treatment Decision

If candidate criteria are met, patient and physician make shared decision about proceeding with Inspire therapy implantation and develop treatment plan.

Important Medical Disclaimer

This information is for educational purposes only and does not constitute medical advice.Only a board-certified sleep medicine physician can determine your candidacy for Inspire therapy through comprehensive medical evaluation.

Candidacy assessment requires review of complete medical history, sleep study data, CPAP trial documentation, physical examination, and DISE procedure results. Individual patient factors may affect qualification beyond the standard criteria listed.
