- This is a short paper talking about the data stored in a CD-ROM, which were obtained from 16 subjects about sleep apnea.
- The physiological signals include electroencephalogram, electromyogram, electrooculogram, invasive blood pressure, respiratory wave, oxygen saturation, and cardiac volume as measured by VEST method.
- Polysomnographic waveforms were displayed on CRT display and edited by using a program called WAVE (Waveform Analyzer, Viewer, and Editor) which was developed at Massachusetts Institute of Technology.
- 16 PSG data is from 60 male subjects with or without sleep apnea syndrome. The mean age of the subjects was 40 (range: 32–56).
- The recording time was between 2 and 7 h according to the patients.
- The physiological signals were digitized at a sampling interval of 250 Hz and 12 bits/sample.
- Header files also include the time of events during polysomnography, such as sleep apnea, or the period of continuous positive airway pressure (CPAP) and recorded on supplement floppy disk.
- QRS annotation files are also included which has the detected QRS wave in ECG.
- Sleep stage files are also included in which the sleep stage was determined by authors according to the criteria of Rechtschaffen and Kales.
