Further study details as provided by Chinese University of Hong Kong:

Primary Outcome Measures:
  • To compare the compliance of auto-CPAP and fixed CPAP in terms of CPAP usage hours.
  • To compare the clinical efficacy of auto-CPAP and fixed CPAP in terms of pressure level to abolish OSA, Epworth sleepiness scale and quality of life questionnaire.
  • To compare patient acceptance of the different type of treatment.

Study Start Date: August 2004
Estimated Study Completion Date: June 2005
Detailed Description:

A prospective, randomized crossover cohort. Study subjects consisted of patients newly diagnosed with obstructive sleep apnea (OSA) confirmed with sleep study. All are CPAP naïve.

Randomization:

Arm 1: auto CPAP sleep study then auto CPAP for 2 months Arm 2: fixed CPAP titration then fixed CPAP for 2 months

Then switch over to the other arm

Trial end after 4 months, compliance and other parameters would be compared between two arms as described in the endpoint session.
