Abstract
Defibrillators with enhanced functionality during cardiopulmonary resuscitation (CPR) periods are described. The enhancements include predicting a length of a charging period of a capacitor of the medical device so that capacitor is shock charged at the end of the CPR period. The enhancements also include re-assessing an electrocardiogram (ECG) signal for continued presence of a shockable rhythm during the CPR period and before administration of a defibrillation shock. Together the enhancements can improve the timing and recommended administration of defibrillation therapy.
