    摘要： The present invention provides a method and device for conveniently setting the volume of a variable-length tubing loop used in a re-breathing circuit to various selected predetermined values. The device includes a card of an inelastic, disposable material which is attachable to a portion of the tubing loop or adjacent structure and which has marked on it several positions to which the tubing loop can be extended to set the volume of the loop at selected predetermined values. The card is preferably formed of a substantially rigid material which may be configured to fold around the tubing loop and adjacent structures to provide support and protection during shipping and handling of the device. The card may include instructions for use of the tubing loop printed on an outer surface thereof. Some or all of the card may be detachable from the tubing loop so that once the desired tubing volume is set, all or a portion of the card may be removed and disposed of.

    摘要： A sidestream sampling system includes a sidestream gas measurement assembly and a sample cell configured to be assembled therewith. The sidestream gas measurement assembly includes a receptacle for removably receiving at least a portion of the sample cell. The sample cell is coupled to a sampling tube that is configured to communicate with an airway of an individual. When the sample cell is assembled with the sidestream gas measurement assembly, a window of the sample cell is oriented toward a corresponding source and/or detector of the sidestream gas measurement assembly to facilitate monitoring of an amount of at least one gas or vaporized material in an individual's respiration.

    摘要： A mainstream gas monitoring system and method that includes using a mainstream airway adapter and a gas sensing assembly associated with the airway adapter to measure an analyte of a gas flow through the adapter. A gas sensing portion outputs a signal indicative of the analyte in a gas flow in the mainstream airway adapter. A processing portion receives the signal from the gas sensing portion and determines an amount of the analyte in the gas flow based on the signal from the gas sensing portion. The processing portion determines whether the oxygen measurements are of sufficient quality for their intended use, such as for measuring oxygen consumption or metabolic estimations. Quality measurements may be used to improve accuracy of derived metabolic estimations. Methods are provided by which carbon dioxide measurements can be processed and substituted for direct oxygen measurement for all or part of a respiratory cycle.

    摘要： A mainstream gas monitoring system and method that includes a mainstream airway adapter, and a gas sensing assembly associated with the mainstream airway adapter to measure an analyte of a gas flow through the adapter. A gas sensing portion outputs a signal indicative of the analyte in a gas flow in the mainstream airway adapter. A processing portion receives the signal from the gas sensing portion and determines an amount of the analyte in the gas flow based on the signal from the gas sensing portion. The gas sensing portion is subject to temperature variations associated with variations in flow rate and direction of respiratory gases. Methods are described that utilize the measurement of instantaneous respiratory flow rate combined with estimates of gas temperature and composition to estimate the sensor cooling effects from which a flow based time varying compensation factor is derived.
