摘要： A system is configured to generate a pressurized flow of gas comprised of a first gas having a partial pressure that varies in a predetermined manner. This may be used, for example, to simulate a previous and/or theoretical respiratory gas flow that was produced (or could have been produced) by a subject. The system is configured to deliver the pressurized flow of gas to a testing system configured to measure the partial pressure the first gas in flows of gas. This may provide an opportunity to determine the response of individual testing systems to various clinical circumstances.

摘要： Gas-pressure-based testing, in some embodiments, features a self-leak-testing module (120) that includes an internal sensor and is configured for measuring, using the sensor, gas leakage (179, 180) from a set of walls that defines respective gas passageways that both exist within the module and are incident to the gas pressure measured. One or more walls of the set may extend outside the module. The module can be configured for deciding, based on a result of the measuring, whether a magnitude of the leakage exceeds a predetermined threshold. A source for applying the pressure may be internal (138) or external (104, 132, 135). Gas pressure based pattern recognition can be used to identify, optionally during treatment and in real time, one or more leak sites responsible for the leakage. The module is implementable as a ventilation monitoring module that measures differential flow of a breathing circuit, the testing serving to prevent cross-contamination of patients.

摘要： Values of components of total carbon dioxide excreted by a subject can be provided. One or more signals may be received conveying information related to a rate of total carbon dioxide excreted by the subject. Based at least in part on the received one or more signals, a first capnometric component and/or a second capnometric component may be determined. The first capnometric component may indicate a rate of metabolic carbon dioxide production. The second capnometric component may indicate a rate of carbon dioxide transfer to or from body compartments of the subject that store carbon dioxide. The first capnometric component and/or the second capnometric component may be presented to a user.

摘要： Respiratory insufficiency is detected by classifying preliminary breaths identified through a capnogram as being valid or artifact. Individual breaths are classified as being valid or artifact by determining values of a plurality of breathing parameters for a given breath, inferring a value for a key parameter from the determined values for the plurality of breathing parameters, and comparing the inferred value for the key parameter to a predetermined threshold.

摘要： Ventilation information may be presented. Output signals may be received that convey information related to one or more breathing parameters of a subject receiving assisted or controlled mechanical ventilation. Based at least in part on the received output signals, volumetric components of a tidal volume of the subject may be determined. The volumetric components may include an alveolar dead space, an effective alveolar tidal volume, and/or other volumetric components. The alveolar dead space is the volume of inspired gas that occupies alveoli but does not take part in oxygen exchange in the lungs of the subject. The effective alveolar tidal volume is the volume of inspired gas that takes part in oxygen exchange in the lungs of the subject. A visual representation that textually or graphically represents the tidal volume, and/or textually or graphically represents the volumetric components separately from each other may be presented via a user interface.

摘要： A system is configured to monitor the dead space fraction of a subject in a substantially ongoing manner, rather than only updating the dead space fraction of the subject if one or more blood gas parameters of the subject are measured. This may facilitate enhanced control over respiratory therapy being provided to the subject, may inform decisions about care of the subject, and/or may provide other enhancements.

摘要： Sidestream sampling of gas to determine information related to the composition of gas at or near the airway of a subject is implemented. From such information one or more breathing parameters of subject 12 (e.g., respiratory rate, end-tidal CO2, etc.) are determined, respiratory events (e.g., obstructions, apneas, etc.) are identified, equipment malfunction and/or misuse is identified, and/or functions are performed. To improve the accuracy of one or more of these determinations, information related to pressure at or near the airway of subject is implemented. This information may include detection of pressure at or near a sidestream sampling cell.

摘要： A system is configured to perform capnometry/capnography, and/or other compositional analysis on a non-invasively ventilated subject. As such, the system determines amounts of a molecular species of gas (e.g., carbon dioxide, oxygen, etc.) excreted by the subject on a per-breath basis. Determinations of amounts of the molecular species of gas excreted are adjusted to reflect amounts of the molecular species of gas leaked from the non-invasive interface used to communicate with the airway of the subject.

摘要： Breaths of a subject are identified based on the concentration of carbon dioxide at or near the airway of the subject. Troughs corresponding to inhalation are identified and plateaus corresponding to exhalation are identified. A breath is identified responsive to a trough being followed by a plateau.
