SYSTEM AND METHOD FOR ANALYSIS OF THE UPPER AIRWAY AND A RESPIRATORY PRESSURE SUPPORT SYSTEM
First Claim
Patent Images
1. A system for analysis of the upper airway, comprising:
- a passageway for communication with a user'"'"'s airway;
a first acoustic sensor positioned at a first location with respect to the passageway;
a second acoustic sensor positioned at a second location with respect to the passageway; and
a processor configured to derive a parameter from the relation between the two sensor signals, which parameter varies in dependence on the presence of an upper airway obstruction,wherein the processor is configured to process sound signals which comprise only ambient noise received from noise sources external to the system for analysis, and noise generated by the user.

Abstract
A system for analysis of the upper airway has at least two sensors are provided along a flow path leading to the mouth and/or nose of a user. A relation is derived between the two sensor signals, and this is interpreted to detect at least the presence of upper airway obstructions, and preferably also the location and/or extent of such obstructions.
