Study to Predict the Benefits of First-line Humidification Use and Comparison of the Effect of ThermoSmart™ and no Humidification on Adherence

Evaluation of Advantages Linked to the Use of Humidification by ThermoSmart During Continuous Positive Airway Pressure

This study aims to investigate the benefits of using first line heated humidification. The primary objective of this research is to determine the effect of high levels of humidification delivered by ThermoSmart™ on CPAP adherence. In addition, to determine if it is possible to predict which patients benefit the most (i.e. be more adherent with therapy) from high levels of humidification delivered by ThermoSmart.
