  • Patent number: 10940324
    Abstract: In embodiments, a WCD system includes electrodes with which it senses an ECG signal of the patient. A processor may detect sequential peaks within the ECG signal, measure durations of time intervals between the peaks, including between non-sequential peaks, and identify a representative duration that best meets a plausibility criterion. The plausibility criterion may be that the representative duration is the one that occurs the most often, i.e. is the mode. Then a heart rate can be computed from a duration indicated by the representative duration and, if the heart rate meets a shock condition, the WCD system may deliver a shock to the patient. An advantage can be that the representative duration can be close to a good R-R interval measurement of a patient, notwithstanding noise in the ECG signal that is in the shape of peaks.

  • Patent number: 10478074
    Abstract: A system and method for determining a patient's suitability for a proposed surgical procedure is disclosed in which a simulated, procedure specific hemodynamic profile of an individual patient is obtained using a hemodynamic simulation module operating on a digital processor using a patient specific hemodynamic calculation parameter set. This is used by a trained clinician to evaluate whether the patient is a suitable candidate to undergo the proposed surgery. The patient specific hemodynamic calculation parameter set is obtained by optimizing a generic hemodynamic calculation parameter set. Optimization is done automatically by adjusting the generic hemodynamic calculation parameter set based on the comparison of simulated profiles corresponding to measured hemodynamic profiles of the patient in a non-operation situation. The automatic adjustment is guided by a Damped Least Squares Method and related algorithms.

  • Patent number: 10335346
    Abstract: Embodiments of the present invention are related to a method and device for the determination and calculation of the depth of chest compressions during the administration of cardiopulmonary resuscitation (CPR). Embodiments use an optical sensor to monitor the distance that a victim's chest is displaced during each compression throughout the administration of CPR. The optical sensor is most commonly an image sensor such as a CMOS or CCD sensor, and more specifically a CMOS image sensor capable of three-dimensional imaging based on the time-of-flight principle. An infrared emitter may illuminate the victim's body and any visible piece of ground beside the victim. As the infrared light interacts with any surfaces it encounters, it is reflected and returns to the image sensor where the time of flight of the infrared light is calculated for every pixel in the image sensor. The distance data is used to gauge the effective displacement of the victim's chest.

  • Patent number: 10292899
    Abstract: A CPR machine (100) is configured to perform compressions on a patient's (182) chest that alternate with releases. The CPR machine includes a compression mechanism (148), and a driver system (141) configured to drive the compression mechanism. A compression force may be sensed, and the driving is adjusted accordingly if there is a surprise. For instance, driving may have been automatic according to a motion-time profile, which is adjusted if the compression force is not as expected (850). An optional chest-lifting device (152) may lift the chest between the compressions, to assist actively the decompression of the chest. A lifting force may be sensed, and the motion-time profile can be adjusted if the compression force or the lifting force is not as expected. An advantage is that a changing condition in the patient or in the retention of the patient within the CPR machine may be detected and responded to.
