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.

Condition Intervention
Diagnosed With OSA and Eligible for CPAP Treatment
Naïve to CPAP Therapy
Initial Proscription of a Nasal Mask
Device: Heated humidification (ThermoSmart)

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Crossover Assignment
Masking: Double Blind (Subject, Investigator)
Primary Purpose: Treatment

Further study details as provided by Fisher and Paykel Healthcare:

Primary Outcome Measures:
  • Adherence [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
    Adherence with treatment per night averaged over total time period measured via internal software on the CPAP device and reported using InfoSmart™ software. The report will include all the supporting information recorded within the CPAP device.

Secondary Outcome Measures:
  • Acceptance [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
    Acceptance / drop-out rate, leak, ESS score, self-reported nasal symptoms, and functional outcomes of sleep questionnaire score
