Processing pulse signal in conjunction with accelerometer signal in cardiac resuscitation
First Claim
1. A cardiac resuscitation device, comprisinga pulse sensor configured to detect pulse information characterizing the cardiac pulse in the patient, wherein the pulse sensor has a pulse sensor output signal as its output, and wherein the pulse sensor output signal contains information characterizing individual pulses, each corresponding to movement of blood in the patient'"'"'s circulatory system;
- an accelerometer configured to detect chest movements of the patient during a series of individual chest compressions, wherein the accelerometer has an accelerometer output signal as its output; and
memory and processing circuits configured to process the pulse sensor output signal in conjunction with the accelerometer output signal to determine, for each of a plurality of individual chest compressions in the series of individual chest compressions, if the individual chest compression actually caused movement of blood thus resulting in an individual pulse.

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.
