  Purpose

Determine the clinical efficacy in terms of Apnea Hypopnea Index (AHI), excessive daytime sleepiness (EDS), nocturnal oxygenation of a nasal Positive end-expiratory pressure (PEEP) valve "Provent" in obstructive sleep apnea. The hypothesis is the efficacy will be better than dental device.


Condition Intervention
Obstructive Sleep Apnea
Adverse Effects
Device: nasal peep valve "Provent"

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Symptomatic patients confirmed of OSA by sleep study (PSG according to AASM criteria or validated level 3 portable monitoring devices with AHI > 10/hr)
  • Not using CPAP for any reasons or patients on dental device but would like to try alternative treatments for OSA.
  • Able to sign informed consent and use the PEEP nasal valve.
  • Age between 18-65 years old.
  • Willing to attend follow up.

Exclusion Criteria:

  • Known nasal problems like deformities or significant rhinitis affecting application of PEEP nasal valve.
  • Unable to sign consent or use PEEP nasal valve.
  • Significant or unstable co-morbidities requiring other forms of treatment for OSA as priority.
  • Coexisting sleep disordered breathing condition other than OSA requiring more complex treatment. E.g. central sleep apnea, significant Cheyne Stokes respiration or hypoventilation syndrome.
