Part 1.Comparison of manual pressure titration in laboratory of sleep disorders with Autoset T APAP device from Resmed. Hypothesis: There is no difference in efficiency between manual and automatical titration.

Part 2. Comparison of CPAP and APAP therapy in the home while 3 month by Questionaire and device data.

Hypothesis: There is a difference in compliance and efficiency between CPAP and APAP mode.

Further study details as provided by Kaiserswerther Diakonie:

Primary Outcome Measures:
  • AHI- score (apnea- hypopnea- index) [ Time Frame: 3 months ]
    AHI (apnea- hypopnea- index): Number of Apneas and Hypopneas/hour as a function of the type of positive airway pressure supply used- automated (APAP) vs. the standard, manually titrated and fixes continuous (CPAP).

Secondary Outcome Measures:
  • Number of device-using hours [ Time Frame: 3 months ]
    Number of device-using hours as a means to assess patient compliance with the treatment

Estimated Enrollment: 60
Study Start Date: June 2001
Estimated Study Completion Date: April 2011
Estimated Primary Completion Date: April 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: CPAP
Use of CPAP as treatment for sleep apnea
Device: APAP - Therapy
automatic positive pressure therapy
Active Comparator: APAP
Use of APAP as treatment for sleep apnea
Device: APAP - Therapy
automatic positive pressure therapy

Detailed Description:

A cross over, simple blind study design has been created for a controlled trial to compare pressure titration and therapy with the Autoset T device.

Part 1: After a baseline polysomnography (PSG) a selected group of patients with obstructive sleep apnea will be titrated in two more nights in a sleep lab under APAP mode and CPAP mode. We compare the sleep quality and the AHI, oxygen saturation, leakage.

Part 2: Over a time range of 12 weeks the patients got two kinds of therapy modes at home: CPAP and APAP (each six weeks. We compare the objective and subjective therapy by compliance, device data, Epworth sleepiness scale, Pittsburgh Sleep Quality Index (PSQI, german version).
