ECG analysis that relatively discounts ECG data of CPR period transitions

摘要

Medical devices, software and methods are provided, for making a decision as to whether to administer electric shock therapy to a patient. The decision is made with respect to ECG data that is discounted at least partially, and sometimes even completely, if it occurs during a transition between chest compression group and a pause for ventilation.

主权项

1. A medical device, comprising:
an energy storage module configured to store an electrical charge; and a processor configured to:
receive ECG data of a patient receiving chest compressions;identify the occurrence of a chest compression group within the received ECG data, the identified chest compression group corresponding to a series of consecutive, substantially periodically repeating chest compressions being administered to the patient;determine, within the received ECG data, a first one of a beginning interval and an ending interval of the identified chest compression group, wherein the beginning interval corresponds to a first chest compression of the chest compression group and the ending interval corresponds to a final chest compression of the chest compression group;analyze a segment of the ECG data that includes both first ECG data occurring within the first one of a beginning interval and an ending interval of the identified chest compression group and second ECG data occurring outside the first one of a beginning interval and an ending interval of the identified chest compression group, the analysis discounting partially but not completely the first ECG data relative to the second ECG data; anddetermine whether stored electrical charge should be guided to the patient based on the analysis.
