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.

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.

Abstract: A method, system and apparatus for the monitoring, diagnosis and evaluation of the state of a dynamic drug display system is disclosed. This invention provides for the rapid cognitive grasp of the overall state of drug combination effects with respect to a dynamic system. The system provides for displayed objects, which change in real-time to show the changes of the functions of the system. In particular, this invention is directed to the processing and display of drug data for the use of doctors in the process of monitoring or administering drugs to patients.

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.

Abstract: A method, system and apparatus for the monitoring, diagnosis and evaluation of the state of a dynamic system is disclosed. This method and system provides the processing means for receiving sensed and/or simulated data, converting such data into a displayable object format and displaying such objects in a manner such that the interrelationships between the respective variables can be correlated and identified by a user. This invention provides for the rapid cognitive grasp of the overall state of a critical function with respect to a dynamic system. The system provides for displayed objects, which change in real-time to show the changes of the functions of the system. It is a highly flexible system which works with a wide variety of applications, including biological systems, environmental systems, engineering systems, economic systems, mechanical systems, chemical systems and the like.

Abstract: Methods for non-invasively determining the cardiac output or pulmonary capillary blood flow of a subject include monitoring the subject's respiration during two ventilatory states. Such a method may include determining parameters of at least one of the ventilatory states based on one or more characteristics of the subject. Data obtained from monitoring the subject's respiration, such as an amount of gas present in exhaled gases and respiratiory flow, may be used to estimate respiratory or blood gas parameters, such as an amount of gas exchanged between blood and gases in the subject's lungs or an indicator of a content of the gas in the subject's blood.

Abstract: A basic life support system (BLSS) includes a processing element and an output element, such as a display screen or an audio output element, for providing an individual with real-time instructions on providing emergency medical care to a patient until paramedics or other healthcare professionals arrive to take over care for the patient. The instructions may be provided as graphics, including animations, as text, audibly, or as a combination of visible and audible elements. The BLSS may be configured for providing emergency medical care to individuals who have suffered from ventricular fibrillation. Accordingly, the BLSS may also include a defibrillation apparatus, an air or oxygen supply, a respiratory interface, one or more sensors, or a combination thereof.

Abstract: Apparatus and methods for non-invasively determining the cardiac output or pulmonary capillary blood flow of a patient using partial re-breathing techniques. The apparatus includes a substantially instantaneously adjustable deadspace volume for accommodating differences in sizes or breathing capacities of various patients. The apparatus may be constructed of inexpensive elements, including one or more two-way valves, which render the apparatus very simple to use and inexpensive so that the unit may be employed as a disposable product. The method of the invention includes estimating the cardiac output or pulmonary capillary blood flow of a patient based on partial pressure of alveolar CO2, rather than on the partial pressure of end tidal CO2, as previously practiced. A computer program for calculating the cardiac output or pulmonary capillary blood flow of a patient is also disclosed.
