Diagnosis

Polysomnography (or ventilatory polygraphy) records apneas during sleep. The Apnea-Hypopnea Index (AHI) defines severity:

  • Mild: 5-15 events/hour
  • Moderate: 15-30/hour
  • Severe: > 30/hour

Treatments

  • CPAP (Continuous Positive Airway Pressure): a nightly nasal mask that keeps the airways open. Reference treatment for moderate to severe forms.
  • Mandibular advancement splint: an oral appliance that advances the lower jaw. Alternative for mild forms.
  • Weight loss: reduces severity in 50% of cases
  • Surgery: in certain specific anatomical situations
