Abstract: A system and method for monitoring the arterial gas concentrations of a patient receiving percutaneous oxygenator support. The system comprises a percutaneous oxygenator for providing medical gases to the venous system of the patient via a catheter. Gases are also removed from the venous system via a catheter. The concentrations and flow rates of the gases provided and removed from the patient are monitored. A CPU analyzes the concentration and flow rate information to compute the arterial gas concentration of the patient.

Abstract: An arrangement and method for detecting spontaneous respiratory effort of a patient receiving ventilatory support by a breathing circuit. The nasal cannula control system includes a nasal cannula assembly having two distinct lumens. A different pressure sensor is positioned to detect the pressure difference between each of the two lumens, thereby determining the differential pressure from within the patient's nostrils and within a breathing mask. The nasal cannula control system includes a gas sampling system such that the amount of a monitored gas discharged or exhaled by the patient can be monitored using the same nasal cannula assembly used to generate the differential pressure signal.

Abstract: A differential pressure transducer determines pressure differentials between respiratory airflows and ambient airflows. Another determines pressure differentials between respiratory airflows and ambient airflows. And another determines pressure differentials between i) respiratory airflows received from a subject and ii) interface airflows received from an area near a cannula. Corresponding respiratory monitoring methods also determine the same.

Abstract: A cannula receives i) first respiratory airflows and second respiratory airflows into separate chambers, and ii) ambient airflows. Another receives i) first respiratory airflows and second respiratory airflows into separate chambers, and ii) interface airflows. And another i) first respiratory airflows and second respiratory airflows into separate chambers from a subject, and ii) interface airflow from an area near a cannula. Corresponding respiratory monitoring methods receive the same.

Abstract: A method for integrating a ventilator device with a monitoring device and other medical devices that allows the function of the monitoring device and medical devices to automatically change based on initiation of a respiratory therapy procedure. In addition, modification of behavior on the part of the ventilator is automatic in response to activation of a medical procedure from the medical device or the monitoring device.
