Patent Images
1. A method for displaying sleep related physiological information, the method comprising:
- outputting an image of a spatial region having a first axis representing time and a second axis intersecting the first axis, the second axis representing at least an intensity measurement; and
outputting within the spatial region provided by the first axis and the second axis an envelope trace of sound associated with sleep, the envelope trace of sound including a plurality of graphical components within the envelope trace;
each of the plurality of graphical components being associated with a determined time provided on the first axis representing time;
whereupon at least one of the plurality of graphical components represents a degree of snoring during the determined time associated with the graphical component.

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 transformed into physiological data of two or more types. Physiological data of two or more types are combined into a compact graphical display representing data from all physiological data types.

-
outputting an image of a spatial region having a first axis representing time and a second axis intersecting the first axis, the second axis representing at least an intensity measurement; and outputting within the spatial region provided by the first axis and the second axis an envelope trace of sound associated with sleep, the envelope trace of sound including a plurality of graphical components within the envelope trace;
each of the plurality of graphical components being associated with a determined time provided on the first axis representing time;
whereupon at least one of the plurality of graphical components represents a degree of snoring during the determined time associated with the graphical component. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8)

9. A method for displaying physiological information associated with a sleep period of a mammal, the method comprising:
-
outputting an image of a spatial region having a first axis representing a time interval associated with the sleep period, and a second axis intersecting the first axis, the second axis representing at least an intensity measurement; outputting within the spatial region provided by the first axis and the second axis an envelope trace of respiratory sound associated with the mammal during the time interval; and outputting within the spatial region provided by the first axis and the second axis a first plurality of graphical components, each of the first plurality of graphical components being associated with a determined time period provided on the first axis representing time, whereupon; at least one of the first plurality of graphical components represents a degree of snoring during the determined time associated with the graphical component, the representation of snoring deriving from a color or texture pattern of the graphical component; and each of the first plurality of graphical components has a top border that substantially conforms to the envelope trace and side borders that are substantially perpendicular to the first axis or substantially conform to the envelope trace. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A method for displaying sleep related physiological information about a mammal, the method comprising:
-
outputting an image of a spatial region having a first axis representing time and a second axis intersecting the first axis, the second axis representing at least an intensity measurement; outputting within the spatial region provided by the first axis and the second axis an envelope trace of sound associated with sleep; and outputting within the spatial region provided by the first axis and the second axis a first plurality of graphical components, each of the first plurality of graphical components being associated with a determined time period provided on the first axis representing time, whereupon; the extent, in a direction parallel to the second axis, of the first plurality of graphical components substantially overlaps the extent in said direction of the envelope trace; each of the first plurality of graphical components is indicative of a first physiological parameter of the mammal during the determined time associated with each of the first plurality of graphical components; and the first physiological parameter is selected from at least one selected from snoring, blood oxygen saturation, and body position. - View Dependent Claims (17, 18, 19, 20, 21)
