Abstract

A cardiac resuscitation device that includes a pulse sensor configured to detect pulse information characterizing the cardiac pulse in the patient, an accelerometer configured to detect chest movements of the patient during chest compressions, and memory and processing circuits configured to process the outputs of the pulse sensor and accelerometer to monitor the effect that chest compressions have on the patient's pulse.
