Abstract: A method for optimizing a gas conversion rate in a respiratory gas analyzer, more particularly for nitric oxide (NO) in the respiratory gas, and an associated device are disclosed.

Abstract: A multifunctional control valve for gas measurement instruments, e.g., for respiratory gas analysis, is disclosed. In at least one embodiment, the multifunctional control valve includes a first inlet opening, an outlet opening, a main line, and a bypass line, wherein a measurement chamber is in the main line, wherein the measurement chamber is arranged downstream of a first multiway valve which can selectively connect the main line or the bypass line with the inlet opening, and wherein the measurement chamber is arranged upstream of a second multiway valve which can selectively connect the main line or the bypass line with the outlet opening.

Abstract: An apparatus for measuring nitrogen monoxide in exhaled air by way of a gas sensor unit (13) having at least one gas sensor (15), has a device for gas conversion (11), wherein a device for gas dehumidification (19) is connected upstream of the device for gas conversion.

Abstract: In a method for recording and evaluating measurements related to the condition of a patient for configuration of a portable, patient-controlled device operated to record the measurements,—at least one measurement describing the condition of the patient is recorded by the device,—the measurement and/or at least one parameter derived therefrom is/are transferred to an evaluation device via a communication connection,—the measurement and/or the parameter is/are evaluated by or on the evaluation device by an expert system and/or an expert to determine patient-specific information,—configuration data ascertained in consideration of the patient-specific information is transferred back to the device via the or another communication connection, and—the device is configured according to the configuration data.

Abstract: An appliance is disclosed for measuring at least one gas analyte in exhaled air. In at least one embodiment, the appliance includes an inlet opening for the introduction of exhaled air (mouthpiece), at least one measuring chamber for receiving a sensor unit, and a conduit which provides a fluid connection from the opening to the measuring chamber, and wherein, depending on the gas analyte that is to be measured, a sensor unit with a suitable gas sensor can be introduced into the receiver.

Abstract: Example embodiments relate to a device for measuring nitrogen monoxide in exhaled air by a gas sensor unit with at least one gas sensor. A device and/or method for oxidation of nitrogen monoxide to nitrogen dioxide may be included. The device and/or method for oxidation of nitrogen monoxide to nitrogen dioxide includes a non-consuming catalyst for catalyzing the oxidation of nitrogen monoxide to nitrogen dioxide.
