Abstract
A method and related system of controlling therapeutic gas provided to a patient in positive airway pressure applications. Some of the illustrative embodiments may be a method comprising supplying therapeutic gas at a first pressure to a first naris of patient during a current respiratory cycle and a subsequent respiratory cycle, selecting a second pressure based on an attribute of airflow through a second naris of the patient, and supplying therapeutic gas at the second pressure to the second naris during the current respiratory cycle.

14. A system comprising:
-
a first blower configured to fluidly couple to a first naris of a patient;
a second blower configured to fluidly couple to a second naris of the patient;
a processor electrically coupled to the first and second blowers;
wherein the processor is configured to command the first blower to a first motor speed over a previous and current respiratory cycle, and wherein the processor is configured to command the second blower a second motor speed during the current respiratory cycle, the second motor speed selected based on an attribute of airflow through the second naris. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A method comprising:
-
individually measuring an attribute of inhalation airflow through each naris of a patient while the patient is supplied positive airway pressure; and
determining if a reduction in airflow is attributable to collapse of the patient'"'"'s upper airway or a reduced airflow of one of the nares. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32)
