Reversal of PAP Failure With the REPAP Protocol

Area of Science:

• Sleep Medicine
• Respiratory Therapy

Background:

• Positive Airway Pressure (PAP) therapy is a common treatment for sleep apnea.
• PAP failure, often due to technology-related issues, necessitates alternative strategies.
• Re-titration of PAP (REPAP) offers a novel approach to address treatment non-adherence.

Purpose of the Study:

• To investigate the efficacy of a re-titration of PAP (REPAP) protocol in patients experiencing previous PAP failure.
• To identify technological factors contributing to PAP failure and assess the impact of technological solutions.
• To evaluate objective and subjective sleep improvements following the REPAP protocol.

Main Methods:

• A retrospective analysis of 273 subjects with prior PAP failure who underwent the REPAP protocol.
• The REPAP protocol involved reassessing and modifying PAP technology, including masks, pressure modes, and settings.
• Objective sleep/breathing metrics and subjective ratings were analyzed to compare PAP users and non-users post-intervention.

Main Results:

• 72% of subjects (196/273) successfully re-initiated PAP use after the REPAP protocol.
• Mask adjustments resolved discomfort/leak in 91.2%, pressure mode changes addressed intolerance in 83.5%, and setting adjustments improved breathing in 96.7%.
• PAP users demonstrated improved objective sleep metrics and reported better sleep quality compared to non-users.

Conclusions:

• Technological issues such as mask discomfort, pressure intolerance, and residual breathing events are primary drivers of PAP failure.
• The REPAP protocol effectively resolved these technological challenges, leading to a significant rate of PAP re-initiation.
• Technological interventions during re-titration are crucial for improving patient adherence and reversing PAP failure.
