Publication number: 20220193431Abstract: Defibrillators with enhanced functionality during cardiopulmonary resuscitation (CPR) periods are described. The enhancements include predicting a length of a charging period of a capacitor of the medical device so that capacitor is shock charged at the end of the CPR period. The enhancements also include re-assessing an electrocardiogram (ECG) signal for continued presence of a shockable rhythm during the CPR period and before administration of a defibrillation shock. Together the enhancements can improve the timing and recommended administration of defibrillation therapy.Type: ApplicationFiled: December 22, 2021Publication date: June 23, 2022Inventors: Fred W.

Publication number: 20220176138Abstract: An example method is performed by a defibrillator that includes a therapy cable receptacle and an electrocardiogram cable receptacle. The method includes displaying a user interface screen that includes a primary channel for displaying a primary waveform and a secondary channel for displaying secondary data. The method also includes detecting a lack of a patient connection for therapy pads and detecting a patient connection for an ECG lead obtained using an ECG electrode cable. In addition, the method includes displaying a representation of an ECG signal obtained using the ECG electrode cable in the primary channel based on detecting the lack of the patient connection for the therapy pads and detecting the patient connection for the ECG lead.Type: ApplicationFiled: December 2, 2021Publication date: June 9, 2022Inventors: Mark Rutzer, Christina Mason, David J.

Publication number: 20220181012Abstract: Systems and techniques to ensure reliable operation of devices, such as medical devices, that are configured to execute installed software are described. A secure software update process for the device utilizes multiple integrity checks in order to prove that software integrity has not been compromised before the device is allowed to be put into service with the software installed thereon. Also described is a computer architecture for an external defibrillator that isolates the execution of installed software applications by separately compiling the code for those applications and by executing the separately-compiled applications on different processors of the defibrillator. Among other things, this allows the defibrillator to be “brought online” faster, such as to deliver a shock to a patient.Type: ApplicationFiled: December 6, 2021Publication date: June 9, 2022Inventors: Dennis M. Skelton, Steven Barry Duke, Richard Mackie, Mark Rutzer, James Wootten, Alexander Frolov, Mark G. Killebrew, Seshadri K. Padmanabha, David B. Stewart, Robert Bales, Dale R. Beuning
