title: A computerized system for acquisition and evaluation of polysomnographic recordings.
abstract: A computer system has been designed for acquisition and evaluation of polysomnographic recordings. The aim is to create a system running on a microcomputer emulating all functions of a conventional chart recorder and offering the advantage of making computer assisted evaluations. We have done 87 investigations in the first year of operation and were fully satisfied by the performance of the system. The standard signals we recorded were SaO2, heart rate, respiratory effort, nasal and oral airflow and ECG, as well as EOG, EMG and EEG. Due to this new method, evaluation of the recording can be done in less time than with strip chart recordings and the use of hundreds of pages of paper per night can be avoided.
