摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： Methods for noninvasively evaluating indicators of cardio-pulmonary performance of a subject, such as cardiac output, pulmonary capillary blood flow, and blood carbon dioxide content, include obtaining data of an expiratory carbon dioxide signal and comparing data generated by an algorithmic lung model to the data of the expiratory carbon dioxide signal of a subject. The variables that are input into the algorithmic lung model are adjusted until the data generated thereby reflects that of the measured expiratory carbon dioxide signal with a desired degree of accuracy. Once the algorithmic lung model replicates the data of the measured expiratory carbon dioxide signal with the desired degree of accuracy, one or more of the input values may be used to determine one or more of the cardiac output, pulmonary capillary blood flow, or a blood gas content of the subject from which the expiratory carbon dioxide signal was obtained.
