Brief Summary

The ExVent is an optional accessory to the O2Vent Optima MAD and provides oral Expiratory Positive Airway Pressure (EPAP). Oral EPAP with the ExVent is designed to provide upper airway support via similar mechanisms of action of nasal EPAP devices in commercial distribution, e.g., passive dilatation of the airway, which reduces flow limitation. Nasal EPAP devices are in commercial distribution as stand-alone therapies for the treatment of OSA. The oral EPAP provided by the ExVent accessory is designed to augment the OSA therapy provided by the O2Vent Optima.

Outcome Measures

Primary Outcomes (1)

  • Change in AHI between baseline AHI and the AHI measured during the in-lab PSG sleep night using the O2Vent Optima + ExVent.

    To demonstrate that the ExVent Accessory (inserted into the O2Vent Optima device) is safe and effective in treating mild to moderate OSA. Statistically significant change in AHI with use of the O2Vent Optima + ExVent compared to baseline AHI value (i.e., no treatment).

    Two Years

Secondary Outcomes (1)

  • Adverse events will be summarized descriptively in terms of type and frequency

Eligibility Criteria

Age21 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male or female subject aged 22 years or older.
  • Subject completed a PSG study within the last 6 months at the investigational site's sleep lab and obtained a baseline AHI confirming a diagnosis of mild to moderate obstructive sleep apnea.
  • Subject (self-reports) that he/she is currently a compliant O2Vent Optima user (i.e., using the device for at least 4 hours/night for at least 5 nights/week).
  • Subject completed initial fitting optimization of the O2Vent Optima device.
  • Investigator has determined that the subject could abstain from use of the oral appliance or other sleep apnea therapies for up to 7 days.
  • Must be able to comply with all study requirements as outlined in the protocol.

You may not qualify if:

  • Male or female subject aged 22 years or older.
  • Subject completed a PSG study within the last 6 months at the investigational site's sleep lab and obtained a baseline AHI confirming a diagnosis of mild to moderate obstructive sleep apnea.
  • Subject (self-reports) that he/she is currently a compliant O2Vent Optima user (i.e., using the device for at least 4 hours/night for at least 5 nights/week).
  • Subject completed initial fitting optimization of the O2Vent Optima device.
  • Investigator has determined that the subject could abstain from use of the oral appliance or other sleep apnea therapies for up to 7 days.
  • Must be able to comply with all study requirements as outlined in the protocol.
  • Oral cavity infection or any other oral or dental condition or problem that would limit patient use of the O2Vent Optima oral appliance.
  • Any concomitant diagnosed or suspected sleep disorder including insomnia or central apnea.
  • History of any prior OSA surgical treatments including RF ablation treatment or palatal stent devices.
  • Concomitant use of any other prescription device for treatment of OSA.
  • Female of child-bearing age who is pregnant or intending to become pregnant during the study participation period.
  • Subject with significant change in weight since completion of the diagnostic baseline PSG study (i.e., ±10% or greater change in total body weight.
  • Subject on a non-stable dose of medications or other agents that may affect sleep and/or PSG (e.g., sedatives or hypnotics).
  • Subject who consumes \> 500 mg caffeine per day (e.g., \> 8 cola-type beverages, \> 5 cups of coffee).
  • Subject who consumes \> 3 alcoholic drinks/day.
  • +1 more criteria
