Obstructive sleep apnea (OSA) is treated primarily with positive airway pressure (PAP), which splints the upper airway during sleep to limit collapse and recurrent desaturation.
Modern devices deliver a continuous or variable pressure prescription set by the care team. Mask choice—nasal, nasal pillow, or full face—affects leak, comfort, and long-term adherence.
Therapy works best when patients receive coaching on fit, humidification, and troubleshooting, alongside follow-up to adjust pressure or interface as symptoms evolve.
