Primary Outcome Measures:
  • apnea-hypopnea index [ Time Frame: at 6 weeks ]
    apneas and hypopneas under therapy


Secondary Outcome Measures:
  • Percentage slow wave sleep, percentage rapid eye movement (REM) sleep, Arousal index, sleep time, sleep efficacy [ Time Frame: at 6 weeks ]
    parameters of sleep quality


Enrollment: 30
Study Start Date: January 2010
Study Completion Date: July 2012
Primary Completion Date: June 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Bilevel
Bilevel therapy
Device: Bilevel therapy (somnovent ST 22, Weinmann, Hamburg, Germany)
nighttime positive airway therapy for 6 weeks
Active Comparator: Servoventilation
servoventilation therapy
Device: servoventilation (Somnovent CR, Weinmann, Hamburg, Germany)
nighttime positive airway therapy for 6 weeks

Detailed Description:
Patients with primary obstructive sleep apnea, who develop complex sleep apnea after CPAP treatment of 4-6 weeks duration were randomized to either receive Bilevel of Servoventilation treatment. Parameters of sleep as well as apnea-hypopnea indices are to be compared.
