The REPAP protocol emphasized changes in pressure modes and settings to address expiratory pressure intolerance and residual breathing events; mask changes were facilitated. Objective sleep and breathing metrics and subjective post-titration ratings were analyzed in subsequent PAP users and non-users.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS:<\/jats:title>\n                    <jats:p>\n                      Following REPAP protocol (average follow-up = 2 y), 196 of 273 subjects with previous PAP failure were PAP users, and 77 were non-users. Previous PAP failure was attributed to technology factors, including pressure intolerance, mask discomfort, adaptation difficulties, and no benefits. At second opinion re-titration, mask changes resolved discomfort, mouth breathing, or leak (91.2% of sample); pressure mode changes resolved expiratory pressure intolerance (83.5%); and pressure setting changes decreased residual breathing events and improved air flow (96.7%), all of which were associated with renewed PAP use. PAP users showed objective sleep improvements on re-titrations and reported better sleep quality than non-users. Multiple logistic regressions showed 2 subjective, re-initiation predictors: (1) post-re-titration ratings of better sleep quality and (2) less anticipated difficulty in using PAP after initial or multiple re-titrations. User rates were significantly higher for subjects completing multiple (\n                      <jats:italic toggle=\"yes\">n<\/jats:italic>\n                      = 158) versus one (\n                      <jats:italic toggle=\"yes\">n<\/jats:italic>\n                      = 115) re-titration (80% vs 61%,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .001).
