<p>A computerized apparatus for assisting an operator in analyzing physiological signals occurring during sleep and in scoring the stages of sleep. To teach the computer system how to analyze the physiological signals and for scoring the stages of sleep, the operator establishes initial values of parameters that distinguish events in the recorded data. Events in a portion of the recorded data are then identified using the initial parameters and the results of this identification are displayed for the operator's review. The operator then classifies the events into those that have been identified correctly and those that have been identified incorrectly. Using this event classification, the computer then adjusts the parameters to conform with the correctly identified events. Alternatively, the operator enters selected physical characteristics about a subject, e.g. the subject's age, sex, etc. These physical characteristics are then used to retrieve an initial protocol from a library of previously recorded protocols. Data recorded for the physiological signals is then scored using this initial protocol after which a second protocol is then retrieved from the protocol library based upon the results of scoring with the initial protocol. Various display formats provided by the computer program allow an operator to review the computer assisted sleep analysis in numerous different ways and to associate textual comments with epochs in the data.</p> |
