    Abstract: A defibrillation device for administering an electrotherapy, such as a dual-sequential defibrillation (DSD) electrotherapy. The defibrillation device can include a defibrillation therapy module, a physiological parameter module and a control module. The defibrillation therapy module can output one or more energies and the physiological parameter module can receive one or more physiological parameters, including electrocardiogram (ECG) data. The control module can analyze the physiological parameters to determine an indication for the administration of an electrotherapy and can determine a DSD electrotherapy. The DSD electrotherapy can be based at least in part on the physiological parameters, the indication for the administration of an electrotherapy or a review of the ECG data.

    Abstract: An example method is performed by a computing device executing instructions stored in data storage, and includes receiving physiologic monitoring data from a plurality of sensors coupled to a patient, receiving information indicating a measurement of patient motion during the patient care event, determining whether the measurement of patient motion is above a threshold, based on determining whether the measurement of patient motion is above the threshold, generating, for the physiologic monitoring data, a respective quality indicator, analyzing, by the computing device, (i) a combination of the physiologic monitoring data from the plurality of sensors and (ii) the respective quality indicator for the physiologic monitoring data to generate a response dependent upon the combination of the physiologic monitoring data as weighted by the respective quality indicator, and based on analyzing, outputting caregiver feedback by the computing device according to the response.

    Abstract: An external defibrillator system is configured with at least two different algorithms for determining the duration of a shock administered to a patient being treated and selects the algorithm based on one or more patient parameters such as, for example, the patient's TTI. The patient's TTI can be measured prior to or while the shock is being administered to the patient. The shock can be, for example, a multiphasic defibrillation or a multiphasic cardioversion shock. The charge voltage of the system's energy storage device can additionally be varied depending on the one or more patient parameters. For example, the system may charge the energy storage device so that the charge voltage is higher or lower than a nominal charge voltage responsive to the patient's TTI is higher or lower compared to an average TTI, respectively.

    Abstract: An example method is performed by a current defibrillator and includes determining that a memory embedded within a therapy cable coupled to the current defibrillator stores data indicative of a previous shock delivered to a patient, the previous being delivered using a previous defibrillator. The method also includes obtaining the data indicative of the previous shock, and setting an energy level for a subsequent shock based on the data indicative of the previous shock. The method further includes delivering the subsequent shock to the patient at the energy level for the subsequent shock.
