  • Publication number: 20050247316
    Abstract: An apparatus for reversing inhaled anesthesia includes a filter for removing one or more anesthetic agents from gases passing therethrough, as well as a component for elevating CO2 levels in gases that are to be inhaled by a subject. The CO2 level-elevating component facilitates an increase in the ventilation of the subject without resulting in a significant decrease in the subject's PaCO2 level and, thus, a decrease in the rate at which blood flows through the subject's brain. A method of reversing the effects of inhaled anesthesia includes increasing the rate of ventilation of an anesthetized subject while causing the subject to inhale gases with elevated amounts of CO2 and while filtering anesthetic agents from such gases.

  • Patent number: 6955651
    Abstract: Methods for estimating the volume of the carbon dioxide stores of an individual's respiratory tract include determining a carbon dioxide store volume at which a correlation between corresponding signals of carbon dioxide elimination and an indicator of the content of carbon dioxide in blood of the individual is optimized. The estimate of the volume of carbon dioxide stores, which comprises a model of the respiratory tract, or lungs, of the individual, may be used as a transformation to improve the accuracy of one or both of the carbon dioxide elimination and carbon dioxide content signals. Transformation, or filtering, algorithms are also disclosed, as are systems in which the methods and algorithms may be used. The methods, algorithms, and systems may be used to accurately and noninvasively determine one or both of the pulmonary capillary blood flow and cardiac output of the individual.

  • Publication number: 20050203432
    Abstract: Apparatus and methods for non-invasively determining cardiac output using partial re-breathing techniques are disclosed in which the apparatus is constructed with an instantaneously adjustable deadspace for accommodating differences in breathing capacities of various patients. The apparatus is constructed of inexpensive elements, including a single two-way valve which renders the apparatus very simple to use and inexpensive so that the unit may be readily disposable. The method of the invention provides a novel means of estimating cardiac output based on alveolar CO2 values rather than end-tidal CO2 values as previously practiced. A program for calculating cardiac output is also disclosed.

  • Publication number: 20050124907
    Abstract: Methods for noninvasively measuring, or estimating, functional residual capacity or effective lung volume include obtaining carbon dioxide and flow measurements at or near the mouth of a subject. Such measurements are obtained during baseline breathing and during and shortly after inducement of a change in the subject's effective ventilation. The obtained measurements are evaluated to determine the amount of time required for exhaled carbon dioxide levels to return to normal—effectively an evaluation of carbon dioxide “washout” from the subject's lungs. Conversely, carbon dioxide and flow measurements may be evaluated to determine the amount of time it takes carbon dioxide to “wash in,” or reach peak levels within, the lungs of the subject following the change in the subject's effective ventilation. Apparatus for effective such methods are also disclosed.

  • Publication number: 20040259750
    Abstract: A process is provided for applying a benefit composition to a fabric article during a fabric enhancement operation. The process may comprise the steps of selecting a desired one of two or more levels of a benefit to be provided by the benefit composition to the fabric article, and selecting one dosage amount for the benefit composition based on the selected benefit level.

  • Patent number: 6824520
    Abstract: The present invention is directed to a reusable respiratory measurement device having a discardable flow tube in which a counter is included in a detachable (discardable) memory unit that removably engages the respiratory measurement device body. The memory unit includes a counter that tracks usage of the respiratory measurement device and disables the respiratory measurement device when usage has reached certain predetermined thresholds. The memory unit is then replaced with a new memory unit which re-enables the respiratory measurement device for further measurements. The memory unit is typically sold as part of a batch or lot of disposable flow tubes in which case the counter value is commonly the same as the number of flow tubes in the batch or lot.

  • Publication number: 20040216743
    Abstract: An apparatus for reversing inhaled anesthesia, which is configured to be positioned along a breathing circuit or anesthesia delivery circuit, includes a filter for removing one or more anesthetic agents from gases passing therethrough, as well as a component for elevating CO2 levels in gases that are to be inhaled by an individual. The apparatus is configured to be positioned between a Y-connector of the breathing circuit and the portion of the breathing circuit that interfaces with the individual. The CO2 level-elevating component facilitates an increase in the ventilation of the individual without resulting in a significant decrease in the individual's PaCO2 level and, thus, a decrease in the rate at which blood flows through the individual's brain. A method of reversing the effects of inhaled anesthesia includes increasing the rate of ventilation of an anesthetized individual while causing the individual to inhale gases with elevated amounts of CO2 and while filtering anesthetic agents from such gases.

  • Patent number: 6803034
    Abstract: The present invention relates to a composition and methods for odor and fungal control in ballistic fabrics and other protective garments. The composition is essentially free of any material that would soil or stain fabric or react negatively with the ballistic fabric or other protective gear. The composition is preferably applied as small particle size droplets, especially from spray containers. The cyclodextrin/surfactant combination, either alone, or in combination with the other ingredients, provides improved antimicrobial and antifungal activity.

  • Publication number: 20040118212
    Abstract: A system for sensing respiratory pressure includes a portable pressure transducer configured to be carried by or proximate to a respiratory conduit, such as a breathing circuit or a nasal canula. The portable pressure transducer may removably couple with a pneumotach, in the form of an airway adapter, disposed along the respiratory conduit. The pneumotach may include two pressure ports positioned at opposite sides of an obstruction, which partially blocks flow through a primary conduit of the pneumotach. Corresponding sample conduits of the portable pressure transducer removably couple with the pressure ports. The pressure ports may have sealing elements which are configured to seal against piercing members of the sample conduits upon introduction of the piercing members therethrough. Upon removal of the piercing members, the sealing elements substantially reseal. Methods for using the system are also disclosed.

  • Publication number: 20030225339
    Abstract: Methods for inducing changes in the effective ventilation of an individual by varying one or more respiratory parameters to derive measurements which may be utilized to calculate measures of hemodynamic performance, e.g., pulmonary capillary blood flow and cardiac output, are provided. The methods of the present invention are used to attain measurements under the wide array of ventilatory modes available with modem ventilation machines to calculate indicators of hemodynamic performance using a differential form of the carbon dioxide Fick equation.
