Abstract
A defibrillator is described which executes a resuscitation protocol having a CPR pause period. The CPR pause period may be interrupted for the acquisition of ECG signal data which is not contaminated by chest compression artifacts. Following the acquisition of ECG signal data, the CPR period resumes and continues for its full period. The ECG signal data acquired during the interruption of the CPR period is analyzed and, if a shockable rhythm is identified, a shock sequence is initiated immediately upon conclusion of the CPR period.
Claims19
A method for using a defibrillator to provide resuscitation therapy to a victim of cardiac arrest, comprising:
- attaching defibrillation electrodes to a subject;
- commencing a CPR period;
- interrupting the CPR period;
- acquiring ECG data during the interruption;
- and
- resuming the CPR period.
A defibrillator which executes a protocol including a CPR period comprising:
- a pair of electrodes;
- a controller, coupled to the electrodes, which acts to sense chest compressions;
- wherein the controller is operable to initiate a CPR period;
- and
- wherein the CPR period is interruptible for the acquisition of ECG signals not containing chest compression artifact from a subject.
A method for using a defibrillator to provide resuscitation therapy to a victim of cardiac arrest, comprising:
- attaching defibrillation electrodes to a subject;
- commencing a CPR period during which chest compressions are applied to the subject;
- monitoring during the CPR period for an interval when ECG signals can be acquired without contamination by chest compression artifacts;
- prior to the end of the CPR period, if no such interval has occurred, prompting an interruption of CPR chest compressions;
- and
- acquiring ECG signals which are not contaminated by chest compression artifacts during the interruption.
