Abstract
A method and related system of leak detection in application of positive airway pressure. At least some of the illustrative embodiments are methods comprising supplying positive airway pressure to a patient, and simultaneously sensing proximate to the patient an attribute of airflow indicative of air leaks. The air leaks could be from a mask used by the patient, or the air leak could be through the patient'"'"'s mouth.

25. A positive airway pressure device comprising:
-
a processor;
a first blower electrically coupled to the processor, the first blower configured to fluidly and sealingly couple to at least the nose of a patient by way of a mask; and
a first sensor electrically coupled to the processor and fluidly independent of the first blower, the first sensor configured to fluidly couple to a leak sensing tube of the mask;
wherein when the first blower provides positive airway pressure to the patient, the processor uses the first sensor to check for attributes airflow indicative of one or both of;
mask leak airflow;
or airflow from the patient'"'"'s mouth. - View Dependent Claims (26, 27)
