An auditory pulse monitor for noninvasively detecting the amplitude of arterial pulses on a beat-by-beat basis. A light-weight optical sensor including a light source and photodetector is adapted for application to the skin surface of a subject over a tissue bed containing an arterial supply. The photodetector generates an output signal proportional to the amplitude of an arterial pulse, and an electronic circuit connected to the photodetector generates a signal having a frequency proportional to the photodetector output signal level. A speaker or other audio indicator connected to the electronic circuit generates an audible tone indicating the amplitude of the arterial pulse. Another aspect of the invention is an improvement in automated or automatic external defibrillators (AEDs). An AED is disclosed which optically detects arterial pulses after delivering a defibrillation shock and signals the need for CPR if it detects inadequate cardiac pumping following successful defibrillation.

A method is provided for controlling an automatic external defibrillator without stopping CPR (primarily chest compressions). While chest compressions continue to be applied to the victim, the system differentiates between (1) a perfusing rhythm that has the capability of leading to a beating heart without a shock and (2) ventricular fibrillation (VF) which sometimes occurs in the presence of ventricular tachycardia (VT), in which there is no capability for leading to a beating heart without a shock. Defibrillation shocks should be applied only when needed and that is in the presence of VF and sometimes in the presence of VT. Electrocardiographic (ECG or EKG) signals obtained from electrodes applied to the patient's chest are analyzed so that the presence of a QRS signal characteristic of a rhythm which has the potential of supporting a beating heart, or the absence of a QRS signal which indicates ventricular fibrillation, may be detected in the presence of artifacts resulting from chest compressions.
