The present disclosure generally relates to systems and methods for delivery of therapeutic gas to patients, using techniques to compensate for disruptions in breathing gas flow measurement, such as when breathing gas flow measurement is unavailable or unreliable. Such techniques include using historical breathing gas flow rate data, such as moving average flow rates, moving median flow rates and/or flow waveforms. At least some of these techniques can be used to ensure that interruption in therapeutic gas delivery is minimized or eliminated.

Compensating for disruptions in breathing gas flow measurement

Nitric oxide generation system

Therapy gas delivery systems that provide run-time-to-empty information to a user of the system and methods for administering therapeutic gas to a patient. The therapeutic gas delivery system may include a gas pressure sensor attachable to a therapeutic gas source that communicates therapeutic gas pressure data to a therapeutic gas delivery system controller, a gas temperature sensor positioned to measure gas temperature in the therapeutic gas source that communicates therapeutic gas temperature data to the therapeutic gas delivery system controller, at least one flow controller that communicates therapeutic gas flow rate data to the therapeutic gas delivery system controller, at least one flow sensor that communicates flow rate data to the therapeutic gas delivery system controller, and at least one display that communicates run-time-to-empty to a user of the therapeutic gas delivery system. The therapeutic gas delivery system controller of the system includes a processor that executes an algorithm to calculate the run-time-to-empty from the data received from the gas pressure sensor, temperature sensor, flow controller and flow sensor, and directs the result to the display.

Systems and methods for delivery of therapeutic gas

Described is an apparatus for monitoring nitric oxide delivery, wherein such apparatus comprises a display that provides a visual and/or numeric indication of the calculated dose of nitric oxide. Also described is a method of monitoring nitric oxide delivery, wherein the breathing gas flow rate and therapeutic gas flow rate are measured and used to determine the calculated dose of nitric oxide, which is then displayed. In some embodiments, an alert is provided when the calculated dose rises above or falls below a predetermined level or range.

Apparatus and method for monitoring nitric oxide delivery

Enhanced performance verification port for therapeutic gas delivery

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.).

Clinical decision support system and methods

Provided herein are systems and methods for delivery of therapeutic gas to patients, in need thereof, by 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.

Systems and method for delivery of therapeutic gas to patients, in need thereof, receiving breathing gas from a ventilator that varies at least pressure and/or flow using enhanced therapeutic gas (NO) flow measurement

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.

Systems and method for delivery of therapeutic gas to patients in need thereof using enhanced breathing circuit gas (BCG) flow measurement

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.
