Abstract: A therapeutic gas delivery system with at least one gas supply subsystem is disclosed. The at least one gas supply subsystem may include a gas source coupling configured to receive a therapeutic gas source and form a fluid flow connection with the therapeutic gas source, a therapeutic gas delivery system controller, and one or more display(s) configured to be in communication over a communication path with the therapeutic gas delivery system controller. The display may be configured to display a graphical, illustrative, or numerical indicator of one or more flow or system parameters.

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.
