Embodiments of the invention include a system and methods for providing status information about resuscitation efforts of a person receiving chest compressions as part of Cardiopulmonary Resuscitation (CPR). A microphone generates a soundtrack by sampling sounds within or around the body of the person receiving CPR. The soundtrack is gated in one or more various ways to eliminate portions of the soundtrack, and analysis performed on the remaining portions. By evaluating the remaining portions of the soundtrack, the system can determine a cardiovascular effect of the compressions and provide status information to the rescuer about the determined cardiovascular effect.
