Arm Intervention/treatment
Experimental: cNEP
cNEP treatment
Device: cNEP
subjects with OSA will be treated with the cNEP device with the goal of reducing the number of apneas and hypopneas
Other Name: continuous negative external pressure

Primary Outcome Measures :
  1. proportion of sustained responders [ Time Frame: two weeks after initiation of treatment ]
    reduction of AHI of >50% and to <15/hr from qualifying PSG

Secondary Outcome Measures :
  1. proportion of initial responders [ Time Frame: at PSG 1, one day ]
    reduction of AHI of >50% and to <15/hr from qualifying PSG

  2. AHI comparison with qualifying PSG [ Time Frame: one day, on three separate study occasions ]
    apnea-hypopnea index

  3. ODI comparison with qualifying PSG [ Time Frame: one day, on three separate study occasions ]
    oxygen desaturation index

  4. SpO2 <90% comparison with qualifying PSG [ Time Frame: one day, on three separate study occasions ]
    oxygen desaturation index <90%

  5. CGI of sleep [ Time Frame: three months, and two weeks, respectively ]
    clinical global impressions of sleep, comparing 3-month baseline with end of two weeks of treatment

  6. CGI of satisfaction with the cNEP device [ Time Frame: after two weeks of treatment ]
    clinical global impressions of the cNEP device

  7. Treatment-emergent adverse events [ Time Frame: two weeks ]
    tabulation of treatment-emergent adverse events
