1. A method for characterizing a state of a patient, comprising:
- identifying a desired physiological state;
identifying an undesired physiological state;
obtaining physiological data from the patient;
identifying epochs of time wherein the physiological data are indicative of the subject having been in the desired physiological state without being in the undesirable physiological state;
rendering a graph wherein;
a first axis corresponds to length of time;
a second axis corresponds to fraction of the summed duration of all epochs;
each epoch is plotted as a rectangle according to the axes.

Abstract
A method for improved visualization of information related to the physiology of a sleeping patient is disclosed. Physiological information from the patient is obtained by a device, converted to digital format, and processed to yield epochs of time based on whether the patient was in a physiologically desirable or undesirable state. The duration of epochs is plotted as a series of rectangles and a quality-of-sleep score is calculated based on the epoch lengths.
