| Typical first-line use | Moderate–severe OSA with acceptable fixed or auto pressure tolerance | High-pressure intolerance, COPD overlap, complex / central apnea pathways where indicated |
| Device and titration complexity | Lower device cost, simpler titration, broadest insurance coverage patterns | Higher modality complexity; requires clear clinical indication and monitoring plan |
| Adherence drivers | Strong long-term adherence data when interface fit and humidification are managed | May improve comfort at high pressures; does not replace mask fit or leak coaching |
| Risk / boundary | May be insufficient for complex sleep apnea or NIV transition needs | ASV and certain BiPAP paths are contraindicated or restricted in specific cardiac populations—verify current labeling |
| When it fits | Home-health and sleep-clinic OSA programs with standard PAP pathways | Pulmonary / sleep programs with documented need beyond CPAP / APAP |
