    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: 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: Based on a capnometry signal, one or more breathing parameters of a subject are determined that require valid breaths by the subject to be distinguished from anatomical events that cause the CO2 content of gas at or near the airway of the subject to fluctuate. To improve the accuracy of one or more of these determinations, gas at or near the airway of the subject is diluted.

    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.
