Clinical Definition

PAP therapy encompasses:

  • CPAP: Continuous positive airway pressure
  • BiPAP: Bilevel positive airway pressure
  • APAP: Automatic positive airway pressure
  • ASV: Adaptive servo-ventilation
  • Other Modes: Various specialized pressure delivery methods

All PAP therapies work by creating a pneumatic splint that prevents upper airway collapse during sleep, thereby eliminating obstructive apneas and hypopneas.

Etymology & History

PAP therapy was invented by Dr. Colin Sullivan in 1980 with the development of nasal CPAP. The concept has since evolved to include various pressure delivery modes for different patient needs.

Reference Values & Interpretation

Normal Values

PAP therapy is considered successful when it reduces AHI to <5 events/hour, eliminates symptoms, and is well-tolerated by the patient with good compliance.

Abnormal Values

PAP therapy failure may result from inadequate pressure settings, mask problems, poor compliance, or treatment-emergent central sleep apnea requiring different approaches.

How It's Measured

PAP therapy effectiveness is assessed through objective data from the device (AHI, leak rates, usage hours) and subjective patient reports of symptom improvement.

Role in Diagnosis

PAP therapy is the primary treatment for moderate to severe OSA and is used after diagnosis is confirmed through sleep studies.

Role in Treatment

PAP therapy is highly effective for treating OSA when properly prescribed and used consistently. It addresses the underlying pathophysiology by preventing airway collapse.
