Abstract
A system and method includes a cardiac resuscitation apparatus connected to an automated external programmable defibrillator (AED) or a semi-automated external programmable defibrillator (SAED) includes an adhesive Doppler pad to detect a pulse signal of a patient. Defibrillation-monitoring pads are connected to the Doppler pad and detect an ECG signal of the patient. A processor integrates the pulse signal and the ECG signal to determine therefrom whether or not shock therapy is advised for the patient.
