Abstract
An apparatus for diagnosing a breathing disorder of a patient that includes a first sensing system that determines a dimension, such as cross-sectional area, of a portion of the patient's airway and a second sensing system that determines an internal load on the airway. A processing system receives the output from the first and second sensing systems and determines a compliance curve that corresponds to a relationship between the measured dimension and a plurality of internal loads on the patient's airway. The processing system also determines at least one characteristic associated with the compliance curve. This characteristic is indicative of a likelihood that the patient suffers from a breathing disorder.
Claims35
An apparatus for diagnosing a breathing disorder of a patient, said apparatus comprising:
- a first sensing system operable to determine a dimension of a portion of said patient's airway;
- a second sensing system operable to determine an internal load on said patient's airway;
- and
- a processing system that receives a first output from said first sensing system and a second output from said second sensing system and determines a compliance curve that defines a relationship between said cross-sectional area and a plurality of said internal loads on said patient's airway and also determines at least one characteristic associated with said compliance curve, said characteristic being indicative of a likelihood that said patient suffers from said breathing disorder.
A method for diagnosing a breathing disorder of a patient comprising:
- determining a plurality of internal loads on said patient's airway;
- determining a dimension of at least a portion of said patient's airway for each of said plurality of internal loads;
- determining a compliance curve corresponding to a relationship between said dimension of said patient's airway and said plurality of said internal loads;
- and
- determining at least one characteristic associated with said compliance curve, said characteristic being indicative of a likelihood that said patient suffers from said breathing disorder.
An apparatus for diagnosing a breathing disorder of a patient comprising:
- means for determining a dimension of a portion of said patient's airway;
- means for determining an internal load on said patient's airway;
- and
- processing means, receiving a first output from said means for determining said cross-sectional area and said means for determining said internal load, for determining a compliance curve that corresponds to relationship between said dimension of said portion of said patient's airway and a plurality of said internal loads on said patient's airway, and for determining at least one characteristic associated said compliance curve, said characteristic being indicative of a likelihood that said patient suffers from said breathing disorder.
