Abstract
An example method includes administering first compressions to a chest of a subject at a first rate; identifying an electrocardiogram (ECG) of the subject; determining, by analyzing the ECG, that the subject has refibrillated; and in response to determining that the subject has refibrillated, administering second compressions to the chest of the subject at a second rate. The second rate is different than the first rate.
Claims20
A system, comprising:
- a defibrillator comprising:
- a detection circuit configured to detect an electrical signal indicative of an electrocardiogram (ECG) of a subject;
- a first processor configured to determine that the ECG is indicative of ventricular fibrillation (VF);
- and
- a treatment circuit configured to output an electrical shock to the subject in response to the first processor determining that the ECG is indicative of the VF;
- and
- a chest compression device communicatively coupled with the defibrillator, the chest compression device comprising:
- a compressor configured to administer compressions to a chest of the subject;
- and
- a second processor configured to:
- determine, by analyzing the ECG, that the subject has transitioned into the VF from a non-VF heart rhythm within a threshold time period after an initial compression among the compressions;
- and
- in response to determining that the subject has refibrillated by transitioning into the VF from the non-VF heart rhythm within a threshold time period after the initial compression, cause the compressor to decrease a rate of the compressions.

A medical device, comprising:
- a compressor configured to administer compressions to a chest of a subject;
- and
- a processor configured to:
- identify an electrocardiogram (ECG) of the subject;
- determine, by analyzing the ECG, that the subject has refibrillated;
- and
- in response to determining that the subject has refibrillated, cause the compressor to change a rate of the compressions.
