Development of the polysomnographic database on CD-ROM.

We have developed a polysomnographic database on CD-ROM. The data were obtained from 16 subjects with sleep apnea syndrome. The physiological signals include electroencephalogram, electromyogram, electrooculogram, invasive blood pressure, respiratory wave, oxygen saturation, and cardiac volume as measured by VEST method. The CD-ROM also include programs to analyze polysomnography (PSG) data. The CD-ROM has values: (i) for researchers investigating clinical physiology or non-linear dynamics during sleep apnea syndrome; (ii) for engineers developing a new algorithm for the computerized analysis of PSG data related to sleep apnea syndrome; (iii) for students learning sleep physiology.
