Abstract: The present invention generally relates to systems and methods for delivery of therapeutic gas to patients, in need thereof, receiving breathing gas from a high frequency ventilator using at least enhanced therapeutic gas (e.g., nitric oxide, NO, etc.) flow measurement. At least some of these enhanced therapeutic gas flow measurements can be used to address some surprising phenomenon that may, at times, occur when wild stream blending therapeutic gas into breathing gas a patient receives from a breathing circuit affiliated with a high frequency ventilator. Utilizing at least some of these enhanced therapeutic gas flow measurements the dose of therapeutic gas wild stream blended into breathing gas that the patient receives can at least be more accurate and/or under delivery of therapeutic gas into the breathing gas can be avoided and/or reduced.

Abstract: A system and method for automatically adjusting medical displays is arranged to communicate medical information to a caregiver. The system includes at least one display for displaying medical information, a wireless communication device associated with the display and a wireless communication device associated with the caregiver. The wireless communication device associated with the display is arranged to realize if the wireless communication device associated with the caregiver, and thus the caregiver, is present in a predetermined area near the display. A controller associated with the display is arranged to automatically adjust at least one characteristic of the display based upon the realized presence of the caregiver. According to the method, the presence of the caregiver is detected when the caregiver enters the predetermined area near the display. At lease one characteristic of the display is thus adjusted automatically based upon the detected presence of the caregiver in the predetermined area.

Abstract: The present invention generally relates to systems and method for delivery of therapeutic gas to patients in need thereof using enhanced breathing circuit gas (BCG) flow measurement. At least some of these enhanced BCG flow measurements can be used to address some surprising phenomena that may, at times, occur when wild stream blending therapeutic gas into breathing gas that a patient receives from a breathing circuit affiliated with a ventilator. Utilizing at least some of these enhanced BCG flow measurements the dose of therapeutic gas wild stream blended into breathing gas that the patient receives from a ventilator can at least be more accurate and/or over delivery of therapeutic gas into the breathing gas can be avoided and/or reduced.

Abstract: The present invention relates to a device and method of delivering inhaled Nitric Oxide (iNO) to a patient situated in a Magnetic Resonance Imaging (MRI) suite.

Abstract: Described are systems and methods for compensating long term sensitivity drift of catalytic type electrochemical gas sensors used in systems for delivering therapeutic nitric oxide (NO) gas to a patient by compensating for drift that may be specific to the sensors atypical use in systems for delivering therapeutic nitric oxide gas to a patient. In at least some instances, the long term sensitivity drift of catalytic type electrochemical gas sensors can be addressed using calibration schedules, which can factor in the absolute change in set dose of NO being delivered to the patient that can drive one or more baseline calibrations. The calibration schedules can be used reduce the amount of times the sensor goes offline. Systems and methods described may factor in in actions occurring at the delivery system and/or aspects of the surrounding environment, prior to performing a baseline calibration, and may postpone the calibration and/or rejected using the sensor's output for the calibration.

Abstract: The present invention provides clinical decision support that can be used with non-portable and portable systems when delivering and/or monitoring delivery of a therapeutic gas comprising nitric oxide to a patient. Further, clinical decision support can be used with non-portable and portable systems during delivery and/or monitoring of delivery of therapeutic gas when nebulized drugs may and/or may not be being delivered to a patient (e.g., when nebulizers are delivered upstream in the inspiratory limb of the breathing circuit, into a breathing gas delivery system, etc.).

Abstract: Described are methods and devices for therapeutic or medical gas delivery that utilize at least one proportional control valve and at least one binary control valve. The proportional control valve may be in series with the binary control valve to provide a valve combination capable of pulsing therapeutic gas at different flow rates, depending on the setting of the proportional control valve. Alternatively, the proportional control valve and binary control valve may be in parallel flow paths.

Abstract: A nitric oxide delivery device is provided that can be formed as a module that is insertable in a mating equipment bay in a gas delivery system found in one location, removed and used in conjunction with a transport gas delivery system when the patient is transported, and thereafter inserted in the equipment bay of a gas delivery system located at a second location. In a preferred embodiment, the device includes a housing having an NO supply port, an NO delivery port, a flow sensor port, and a conduit pneumatically connected to the NO supply port and the NO delivery port. A selector valve is positioned in the conduit and selectively moves between a first position wherein the NO supply port is pneumatically connected to the NO delivery port and a second position wherein the NO delivery port is pneumatically connected to a temporary supply of NO.
