  • Publication number: 20180068589
    Abstract: A method and apparatus to simulate intrauterine contractions to train clinicians in using a tocodynamometer (TOCO) transducer. The apparatus includes an enclosure housing an air bladder, with an opening in the enclosure for a TOCO transducer to be placed in contact with the air bladder. The air bladder is selectively pressurized by a source of compressed gas, the flow being controlled by a flow valve. A pressure release valve is provided to reduce pressure in the bladder. A pressure sensor monitors the bladder pressure, and can be used to calibrate the system to determine what bladder pressure produced a given uterine activity. The flow valve may be controlled by a software run on a processor to achieve particular uterine activity levels over a given period of time.

  • Publication number: 20160166797
    Abstract: A method and apparatus to deliver a variable flow of oxygen to a patient is described. The apparatus may include a flow control valve, a pressure sensor to detect a patient's breathing pressure and ambient pressure, an oxygen flow analyzer to measure oxygen flow to the patient, and a processor to analyze the breathing pressure values, ambient pressure value, and oxygen flow rate values and to determine when a patient is inhaling. When the processor determines the patient is inhaling, the processor calculates an optimal oxygen flow rate to deliver to a patient, which may depend on a pre-selected flow rate and an oxygen backlog, and the processor sends a signal to the flow control valve to deliver the optimal oxygen flow rate to the patient.

  • Publication number: 20160166796
    Abstract: A method and apparatus to identify the source of oxygen delivery failure to a patient. The apparatus comprises a pressure sensor to detect a patient's breathing pressure and ambient pressure, an oxygen flow analyzer to measure oxygen flow to the patient, and a processor to analyze the breathing pressure values, ambient pressure value, and oxygen flow rate values. When the oxygen flow rate value is greater than a predetermined threshold value, the processor is programmed to compare the breathing pressure values to the ambient pressure value and output an apnea alarm or an oxygen delivery device displacement alarm.

  • Patent number: 8801625
    Abstract: Methods for noninvasively determining a pulmonary capillary blood flow or a cardiac output of a subject include determining data of the amount of gas exchanged between blood and gas in lungs of the subject, as well as data of an indicator of the content of the gas in blood of the subject. Such a determination may be made during two or more different states of ventilation. A geometric relationship is identified between data points, with any data points outlying the geometric relationship being disregarded. The remaining data points may be used to estimate or calculate a measure of pulmonary capillary blood flow or cardiac output. Systems that include elements that are configured to effect such methods are also disclosed.

  • Patent number: 8696591
    Abstract: A mainstream gas monitoring method includes a using 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 processing portion also compensates for volumetric differences between the gas flow during inspiration and the gas flow during expiration to maximize the accuracy in the measurements.

  • Patent number: 8671942
    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: 8398559
    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.
