Patent number: 11938332Abstract: A method to provide feedback, coaching, and ECG analysis during a cardiac event. A rescuer would typically be attempting cardiopulmonary resuscitation (CPR) and/or administering an electrical shock from a defibrillator and/or collecting electrocardiogram (ECG) data. The method includes a step of providing a data-generation device (e.g., a camera) and computing components. The computer is used to calculate distances on the fly using data generated by the data-generation device, such as a camera, that may be in motion. The method uses the computer to calculate movement of the chest of a patient and to assess outcomes. When CPR contaminates an ECG, the computer removes the unwanted contamination so that proper guidance to the rescuer can be delivered during CPR.Type: GrantFiled: November 24, 2021Date of Patent: March 26, 2024Assignee: Altrix Medical, Inc.Inventors: Matthew Robert Shaker, Daniel Fleck

Patent number: 11918321Abstract: The invention provides a body-worn monitor that measures a patient's vital signs (e.g. blood pressure, SpO2, heart rate, respiratory rate, and temperature) while simultaneously characterizing their activity state (e.g. resting, walking, convulsing, falling). The body-worn monitor processes this information to minimize corruption of the vital signs by motion-related artifacts. A software framework generates alarms/alerts based on threshold values that are either preset or determined in real time. The framework additionally includes a series of ‘heuristic’ rules that take the patient's activity state and motion into account, and process the vital signs accordingly. These rules, for example, indicate that a walking patient is likely breathing and has a regular heart rate, even if their motion-corrupted vital signs suggest otherwise.Type: GrantFiled: April 26, 2021Date of Patent: March 5, 2024Assignee: SOTERA WIRELESS, INC.Inventors: Devin McCombie, Matt Banet, Marshal Dhillon, Jim Moon

Patent number: 11911095Abstract: A method for generating a propagation and velocity maps for cardiac wavefront propagation including cardiac arrhythmia, sinus rhythm, and paced rhythm. Activation time information is generated in the absence of any time alignment reference, wherein an estimated activation time is a weighted summation of potentially nonlinear and nonorthogonal candidate functions (CFs) selected from a bank of CFs. Time alignments between sequential recordings may be done by including binary level functions among selected CFs. Embodiments are applicable to single catheter mapping and sequential mapping, and are robust as confirmed by the ability to generate propagation maps and conduction velocity in the presence of multiple colliding wavefronts. The propagation and conduction velocity maps may be used for one or more of diagnosing cardiac arrhythmia, localizing cardiac arrhythmia, guiding catheter ablation therapy of cardiac arrhythmia, and guiding cardiac pacing therapy.Type: GrantFiled: September 25, 2020Date of Patent: February 27, 2024Assignees: Queen's University at Kingston, Kingston Health Sciences CentreInventors: Mohammad Hassan Shariat, Damian P.
