[Pneumology. Treatment of obstructive sleep apnea by continuous positive airway pressure: new options]

Continuous Positive Airway Pressure (CPAP) is accepted as first line therapy for Sleep Obstructive Apnea-Hypopnea Syndrome. Over the past few years, several new devices have been made available, aiming to improve patient comfort and compliance. In 25 years, major changes in technology have occurred, and CPAP has evolved from fixed pressure devices to auto-adjusting bi-level positive airway pressure. The algorithms and software of the newly commercialized devices are sometimes difficult to apprehend. In spite of impressive changes in technology, an obvious benefit in terms of compliance or comfort is yet to be demonstrated, and independent validations of these new devices are necessary.
