Abstract

A sleep analysis system (11) for analyzing a sleep episode of a subject (10) based on measured values of a plurality of parameters characterizing that subject. Portions of the measured parameter signals (Figs. 3A-3H) are classified as significants evens (boxes about signal portions in Figs. 3A-3H), and the significant events are segregated (see Fig, 4) based on parameter signal criteria and time correlation as a basis for tbe analysis.
