Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Hypothesis: Computer controlled continuous positive airway pressure (autoCPAP) is equally effective in improving obstructive sleep apnea syndrome symptoms, breathing disturbances, objective vigilance, and it is cost-effective compared to conventional fixed continuous positive airway pressure.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

1. To investigate whether computer controlled continuous positive airway pressure (autoCPAP) improves subjective sleepiness, quality of life, objective vigilance, and nocturnal respiration to a similar degree as conventional fixed continuous positive airway pressure in the initial phase of treatment and over the subsequent 2 years during home therapy
2. To investigate the cost of autoCPAP compared to fixed CPAP therapy
