[Auto CPAP Set system for diagnosis and therapy of sleep breathing disorders].
OBJECTIVE
To compare the Auto CPAP Set system with standard polysomnography (PSG) in diagnosis and therapy of sleep breathing disorders.


METHODS
Two studies were completed. The Auto CPAP Set system was compared with a simultaneously obtained PSG in eleven patients with sleep breathing disorders. Twenty-three additional patients with obstructive sleep apnea syndrome (OSAS) were treated by Auto CPAP Set. Student's t test was employed to evaluate statistical significance.


RESULTS
No differences were found between these two systems in AHI, SaO2 and the longest apnea duration (P > 0.05), and the Auto CPAP Set system had a sensitivity of 70% and a specificity 100% for diagnosis of OSAS. AHI decreased and SaO2 increased significantly in OSAS patients after treatment.


CONCLUSIONS
The Auto CPAP Set system provides an accurate and simple method for diagnosis and therapy of sleep breathing disorders, and the time required for analysis of test results was shorter as compared with PSG.
