Treatment options for Obstructive Sleep Apnea (OSA)

Obstructive Sleep Apnoea (OSA) results form a mechanically blocked airway passage. ResMed is committed to bringing people with OSA a better quality of life, by offering a number of comfortable and effective treatment options.

Three forms of Positive Airway Pressure (PAP) therapy include CPAP, APAP and bilevel. Other solutions include:


  • Oral appliance therapy – Mandibular Repositioning Devices (MRD)
  • Adaptive- servo ventilation


Positive airway pressure (PAP) therapy


Positive airway pressure therapy is the most effective way to treat Obstructive Sleep Apnoea. By creating a “pneumatic splint” for the upper airway, PAP therapy prevents the soft tissues of the upper airway from narrowing and collapsing. Pressurised air is sent from a therapy device through air tubing and a mask to the upper airway.

Positive airway pressure therapy can be delivered in a number of ways:

  • Continuous positive airway pressure (CPAP): pressurised air at one fixed pressure.
  • Automatic positive airway pressure (APAP) therapy: automatically varying air pressure, which changes pressures based on your own breathing.
  • Bilevel therapy: two levels of air pressure that are set to coincide with your inspiratory and expiratory efforts, which may be prescribed by doctors to patients who have difficulty following other treatments.
