Abstract: Hose connection system for narially sensitive diagnostic devices. At least some of the illustrative embodiments are systems including a test device and a nasal cannula. The test device includes a first port configured to sense an attribute of airflow, and a second port configured to sense an attribute of airflow. The nasal cannula includes a first hose configured to fluidly couple on a device-end to the first port (and the first hose configured to fluidly couple between the first port and a first naris of a patient), and a second hose configured to fluidly couple on a device-end to the second port (and the second hose configured to fluidly couple between the second port and a second naris of the patient). The nasal cannula is configured such that the first hose only couples to the first port and the second hose only couples to the second port.

Abstract: 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.

Abstract: A method and system of coordinating an intensifier and sieve beds. At least some of the illustrative embodiments are methods comprising coordinating control of an intensifier with cycles of a sieve bed fluidly coupled to the intensifier such that there is at least one low pressure stroke of the intensifier and at least one high pressure stroke of the intensifier during a fill cycle of the sieve bed.

Abstract: A method and system of operating a trans-fill device. At least some of the illustrative embodiments are methods comprising generating an enriched gas stream from atmospheric air, and operating an intensifier which, when provided the enriched gas stream, produces a cylinder fill gas stream. The operating continues in the absence of the enriched gas stream being provided to the intensifier.

Abstract: System and method of a positive airway pressure device gathering data as to apnea type. At least some of the illustrative embodiments are systems comprising a processor, and a blower mechanically coupled to a motor (the blower configured to fluidly couple to a breathing orifice of a patient, and the blower provides substantially all gas inhaled by the breathing orifice). The processor is configured to monitor for an apnea event of the patient, and when an apnea event is detected the processor is configured to gather data indicative of whether the apnea is central apnea or obstructive apnea.

Abstract: Hose connection system for narially sensitive diagnostic devices. At least some of the illustrative embodiments are systems comprising a test device and a nasal cannula. The test device comprises a first outlet port configured to sense an attribute of airflow, and a second outlet port configured to sense an attribute of airflow. The nasal cannula comprises a first hose configured to fluidly couple on a device-end to the first outlet port (and the first hose configured to fluidly couple between the first outlet port and a first naris of a patient), and a second hose configured to fluidly couple on a device-end to the second outlet port (and the second hose configured to fluidly couple between the second outlet port and a second naris of the patient). The nasal cannula is configured such that the first hose only couples to the first outlet port and the second hose only couples to the second outlet port.

Abstract: 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.
