DETECTING AND ADDRESSING IRREGULAR MOTION TO IMPROVE DEFIBRILLATION SHOCK RECOMMENDATIONS

Abstract:

Systems, devices, and methods for detecting and addressing irregular motion to improve defibrillation shock recommendations are described. In an example method performed by a medical device, an electrocardiogram (ECG) of an individual receiving chest compressions is detected. In addition, irregular motion of the individual is detected. If a magnitude of the irregular motion is greater than or equal to a threshold, a remedial action is performed. In some examples, the medical device refrains from generating a recommendation indicating whether the ECG includes a shockable rhythm and/or whether a defibrillation shock is recommended. In some instances, the medical device outputs the recommendation with a certainty of the recommendation. In some cases, the medical device outputs a warning and generates the recommendation in response to receiving an input signal indicating a manual override.
