A Study to Determine if a Mask-fitting App Using Facial Recognition Improvea Clinical Care for Patients Using Positive Airway Ppressure Devices?


About this study

The purpose of this study is to evaluate whether use of the app to recommend positive airway pressure (PAP) masks reduces patient-initiated request for mask changes during the first 90 days of PAP use., and to evaluate whether use of the app results in improved patient satisfaction with PAP experience during the first 90 days of PAP use.

More information


  • Patient interface preference is a key factor in positive airway pressure compliance. Local side effects are common. Proper mask fitting and patient education are important. Masks should seal well and fit comfortably. Nasal, nasal pillow, and oronasal masks can be effective interfaces. Most patients with obstructive sleep apnea prefer a nasal mask. Oronasal masks can be a useful alternative. Nasal pillows can reduce mask size and improve comfort. Oronasal masks may require a higher pressure. A significantly lower pressure may be effective with a nasal interface. Proper mask fitting requires testing the mask seal under the treatment pressure. Read More on PubMed
  • The demand for continuous positive airway pressure (CPAP) therapy outpaces available resources in most health care settings. We sought to evaluate predictors of nonroutine CPAP follow-up visits to improve resource utilization. Read More on PubMed
