  • Patent number: 11813084
    Abstract: A method for measuring a myocardial physiologic parameter according to an embodiment includes placing an at least partially convex portion of a spectral sensor against an intercostal space of a human over a heart of the human and measuring the physiologic parameter of a myocardium of the heart with the spectral sensor over time during an emergency medical event. The spectral sensor may be configured to determine and visually display a suggested position adjustment for directing the spectral radiation more directly toward the tissue of interest (e.g. the myocardium), and/or for placing the operative elements of the spectral sensor closer to the tissue of interest (e.g. the myocardium).

  • Patent number: 10799177
    Abstract: A system for non-invasively measuring a physiologic status patient tissue according to an embodiment includes a housing; an optical spectroscope with a wavelength-sensitive sensor capable of detecting light intensity, at two or more distinct wavelengths, of light scattered and/or reflected by muscle tissue of the patient in order to measure a physiologic status of the muscle tissue, a bioimpedance sensor at least partially disposed within the housing, the bioimpedance sensor configured to generate a signal corresponding to an estimation of a thickness of an adipose tissue layer between the optical spectroscope and the muscle tissue, and a processor configured to (1) receive the estimations of the thickness, (2) compare the estimations of the thickness, and (3) based on the comparison, generate a visual indication configured to assist in placement of the housing toward or at a location corresponding to the smaller or smallest thickness of the adipose tissue layer.

  • Publication number: 20200305722
    Abstract: Embodiments of the present disclosure relate generally to the use of spectral sensors during a cardiac arrest event. More specifically, the present disclosure relates to the use of spectral sensors for measuring changes in pH and muscle oxygen saturation to estimate subject down time and evaluating the effectiveness of the clinical treatment administered during a cardiac arrest event. Given the narrow window of time in which emergency treatment must be administered, as well as the lack of information concerning the subject's condition, there is a need for a fast and accurate method of estimating the onset of the cardiac arrest emergency and evaluating the effectiveness of the emergency treatment being administered.

  • Patent number: 10378972
    Abstract: Systems and methods for determining validity of physiological data according to an embodiment of the present invention include a patient sensor configured to acquire patient data from a patient, wherein the patient data is physiological; and an environmental sensor configured to acquire environmental data related to validity of the patient data, wherein a value of the environmental data has a clinical effect on the validity of the patient data but not on performance of the environmental sensor; a control/monitoring system, wherein the control/monitoring system is configured to determine whether the environmental data satisfies one or more conditions indicative of the validity of the patient data and to flag the patient data that is invalid based on the determination.
