    摘要： A method and related system to determine nasal resistance to airflow. Some of the exemplary embodiments may be a method comprising measuring an attribute of airflow through a first naris of a patient without blocking a second naris of the patient, measuring an attribute of airflow through the second naris of the patient without blocking the first naris, and determining a value indicative of nasal resistance to airflow based on the attributes measured.

    摘要： A nasal cannula. Some illustrative embodiments are a cannula comprising a first nasal tube having a device end and an aperture end (the cannula configured to place the aperture end in fluid communication with the first naris of a patient), a second nasal tubing having a device end and an aperture end (the cannula configured to place the aperture end of the second nasal tubing in fluid communication with a second naris of the patient), and an oral tubing having a device end and an aperture end, and the oral tubing mechanically coupled to at least one of the first or second nasal tubing (the cannula configured to place the aperture end of the oral tubing in fluid communication with the mouth of a patient). The first nasal tubing, the second nasal tubing and the oral tubing are fluidly independent between their aperture ends and their device ends.

    摘要： A method and system for providing therapeutic gas to a patient during positive airway pressure ventilation and, more particularly, detecting the presence of a mouth leak during ventilation and, upon the detection of a mouth leak, reducing the applied pressure so as to reduce irritation and discomfort experienced by the patient. Respiratory air flow from a patient is measured in a waveform as a function of time. An approximate value of the root mean square voltage of the waveform is established during a period in which the patient is experiencing a mouth leak and a root mean square voltage of the waveform is established during a period in which the patient is experiencing an apneic event. The waveform is subsequently monitored and the rate of respiratory airflow is decreased when there is an indication of a mouth leak provided there is no indication of an apneic event.
