Sleep-Wakefulness Determinations from Heart Rate Data.

Abstract

In recent years a number of projects related to the automated classification of levels of alertness have been conducted in the Bio-Medical Engineering Program. All of these projects were designed with a common goal in mind: the development of a process by which rapid, inexpensive determinations of levels of alertness could be performed accurately using an easily derived physiologic parameter such as beat-by-beat heart rate. By combining procedures and results of these previous studies a conglomerate algorithm can be developed which has all the necessary capabilities. One of the primary goals was achieved: the reduction of cost, volume, and complexity in automated classification of levels of alertness. It was felt that improvements can be made which will provide substantial progress toward fulfilling the remainder of the goals: the development of an automated process for the accurate determination of levels of alertness.
