  • Publication number: 20120055481
    Abstract: An apparatus for reversing inhaled anesthesia, which may be configured to be positioned along a breathing circuit or anesthesia delivery circuit, includes an anesthesia removal component and a blood flow acceleration component. The blood flow acceleration 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 at least atmospheric amounts of CO2.

  • Patent number: 8096297
    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.

  • Patent number: 7891356
    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.

  • Publication number: 20100269828
    Abstract: Systems, methods, and apparatus for removing volatile anesthetics from an anesthesia or ventilation system to minimize the effects of malignant hyperthermia in susceptible patients. According to one aspect of the present invention, a system for removing volatile anesthetics is provided. A first filter component placed in fluid communication with an inspiratory limb of an anesthesia or ventilation system such that volatile anesthetics will pass through the first filter component during operation of the anesthesia or ventilation system. A second filter component is operably coupled to the expiration port of the anesthesia or ventilation system such that gases passing through the expiratory limb of the anesthesia or ventilation system pass through the second filter component. The first filter component and second filter component are adapted to effectively remove volatile anesthetics passing through the respective filters.

  • Patent number: 7788963
    Abstract: One aspect of the invention relates to a system adapted to calibrate a determination of information related to one or more gaseous analytes in a body of gas being delivered to an objective by a gas source. In one embodiment the system comprises a partial pressure sensor, a total pressure monitor, a partial pressure module, and a calibration module. The partial pressure sensor generates an output signal related to the partial pressure of the one or more gaseous analytes in the body of gas. The total pressure monitor determines the total pressure of the body of gas. The partial pressure module determines the partial pressure of the one or more gaseous analytes in the body of gas according to a partial pressure function, wherein the partial pressure function describes the partial pressure of the one or more gaseous analytes in the body of gas as a function of the output signal generated by the partial pressure sensor.

  • Publication number: 20100106040
    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.

  • Patent number: 7699788
    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: 20100036272
    Abstract: A system (300) for measuring a metabolic parameter. The system includes an integrated airway adapter (20, 100, 200) capable of monitoring any combination of respiratory flow, O2 concentration, and concentrations of one or more of CO2, N2O, and an anesthetic agent in real time, breath by breath. Respiratory flow may be monitored with differential pressure flow meters under diverse inlet conditions through improved sensor configurations which minimize phase lag and dead space within the airway. Molecular oxygen concentration may be monitored by way of luminescence quenching techniques. Infrared absorption techniques may be used to monitor one or more of CO2, N2O, and anesthetic agents.

  • Publication number: 20080161711
    Abstract: 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.
