An automatic sleep analysis system using a super mini-computer was developed. The system improved and expanded the data processed by the mini-computer. It had the following features: 1) wave-forms were collected and analyzed at a high speed (reproduced at 10 or 20 times the speed of a data recorder) by an off-line procedure to utilize the computer resources more efficiently; 2) all information and the original wave-forms were output to a laser printer because of the lower cost and more efficient arrangement of the data; 3) various wave-form parameters were measured by wave-form analysis; 4) the application program was based on general-purpose language; and 5) wave-form reanalysis and reconstruction of the logic was easily implemented for automatic evaluation of the sleep stages. Automatic analysis of the sleep stages was impossible for 15 of 1484 periods (20 sec per period) with one of the cases analyzed, and 142 of 1484 periods had to be corrected because of erroneous identification.
