Abstract: A medical device can include a housing, an energy storage module within the housing to store an electrical charge, and a defibrillation port to guide via electrodes the stored electrical charge to a person in need of medical assistance. The medical device can also include a processor to perform a patient signal analysis on an electrocardiogram (ECG) signal corresponding to the person and further determine, based on a result of the patient signal analysis, whether post-shock transcutaneous pacing should be performed on the person.

Abstract: A CPR chest compression machine includes a retention structure that is configured to retain a body of the patient, and a compression mechanism. The compression mechanism is coupled to the retention structure and configured to perform successive compressions to the patient's chest. Various types of chest compressions may be performed on a patient during a single resuscitation event. Some embodiments also include a driver configured to drive the compression mechanism. The compression mechanism may thus perform chest compressions that differ from each other in a number of aspects, for example the depth of the compressions or the height of the active decompressions between the compressions. Some embodiments also include an adjustment mechanism. The adjustment mechanism may shift the compression mechanism with respect to the patient so that the chest compressions are performed at different locations of the patient's chest.

Abstract: The defibrillator may include a heart rhythm detector to detect the heart rhythm of a patient, a manual mode controller structured to set the defibrillator in a synchronous shock operating mode or an asynchronous shock operating mode depending on an input from a human operator, a shock module to cause the defibrillator to deliver a shock to the patient according to the operating mode, and an automatic mode controller structured to, after the shock module has delivered the shock to the patient, set the external defibrillator to the synchronous shock operating mode or the asynchronous shock operating mode depending on the detected heart rhythm of the patient and without input from the human operator.

Abstract: Various types of chest compressions may be performed on a patient during a single resuscitation event. In embodiments one or more compression time parameters may be changed during the event, potentially optimizing blood flow for one side of the patient's heart, then the other. In some embodiments the event includes one or more prolonged compressions interposed between other compressions, potentially enabling the blood to reach to more remote locations than otherwise. In embodiments, a CPR chest compression machine includes a compression mechanism configured to perform successive compressions to the patient's chest, and a driver configured to drive the compression mechanism accordingly. In embodiments, a CPR metronome issues prompts for compressions accordingly.

Abstract: Disclosed are embodiments of a laryngoscope that facilitates targeted recording (video, or audio, or both video and audio) of time intervals associated with active laryngoscopy. In accordance with the teachings of the disclosure, a characteristic that reliably defines the interval of active laryngoscopy is used to trigger recording. One such characteristic is that the operator's hand is gripping the handle of the laryngoscope. Accordingly, preferred embodiments implement a laryngoscope having a handle so designed that when the handle is gripped by the operator's hand, recording is initiated and continued for as long as the operator's hand maintains a grip on the laryngoscope handle.

Abstract: Devices, systems, software and methods for CPR quality assessment. Patient data is received that may be derived from a session of administering sets of CPR chest compressions to a patient. The sets can be separated by pauses. Then a figure of merit (FOM) can be computed from the data in the computation, at least one pause can contribute a penalty to the FOM. The penalty has a value determined from at least one control factor, other than a constant linear dependence on the duration of the pause. This way, pauses can incur penalties to the FOM computation depending on their context, instead of merely their duration. For example, a penalty can escalate non-linearly if its pause becomes unduly long, or if it follows a set of chest compressions that was unduly short. As such, a better CPR quality assessment is achieved.

Abstract: An external defibrillator may have a controller to set the defibrillator in a synchronous shock operating mode or an asynchronous shock operating mode, a shock module to cause the defibrillator to deliver shock therapy to a patient according to the present operating mode of the defibrillator, and a heart rhythm detector to detect a heart rhythm of the patient. The defibrillator may also have a mode assessment module to determine whether the present operating mode or selected defibrillation energy of the defibrillator is appropriate based on the detected heart rhythm of the patient.

Abstract: An external defibrillator, such as a wearable defibrillator can have a heart rhythm detector to detect the heart rhythm of a patient. The defibrillator can also have a synchronous shock operating mode and an asynchronous shock operating mode. A controller can set the defibrillator in the synchronous shock operating mode or the asynchronous shock operating mode. The defibrillator can also include a shock module to cause the defibrillator to deliver shock therapy to the patient according to the operating mode of the defibrillator and a sync module configured to identify a first portion of the heart rhythm detected from a first ECG lead with which to time the delivery of the shock therapy to the patient when the operating mode of the defibrillator is in synchronous shock operating mode. A comparator module can compare timing of a QRS complex detected from the first ECG lead with the timing of the QRS complex detected by the second EGG lead.
