CPF Feedback Method and Apparatus

A chest compression detector device that measures chest compression during administration of cardiopulmonary resuscitation to a patient comprising:

• a chest compression sensor configured to be positioned on the chest of the patient, adapted to emit one or more ultrasonic pulses into the chest of the patient and adapted to subsequently receive the one or more ultrasonic pulses reflected off the spine of the patient to generate a measurement signal related to a magnitude of chest compressions and to a frequency of chest compressions;
• a control system being in communication with the chest compression sensor, the control system processing the measurement signal communicated from the chest compression sensor related to the magnitude of the chest compressions and to the frequency of chest compressions;
• and
• a circuitry operably coupled to the control system to receive communication signals from the control system and generate a prompt for use by the rescuer in resuscitating the victim, the prompt being related to the measurement signal communicated to the control system by the chest compression sensor.

A chest compression detector device that measures chest compression during administration of cardiopulmonary resuscitation to a patient comprising:

• chest compression sensor means configured to be positioned on the chest of the patient, the chest compression sensor means including means for broadcasting an ultrasonic pulse, means for receiving the ultrasonic pulse and means for generating a measurement signal related to a magnitude of chest compressions and to a frequency of chest compressions in response;
• control means in communication with the chest compression sensor, the control system means for processing the measurement signal communicated from the chest compression sensor related to the magnitude of the chest compressions and to the frequency of chest compressions;
• and
• prompting means operably coupled to the control means for receiving communication signals from the control means and for communicating prompts to the rescuer for use by the rescuer in resuscitating the victim, the prompts being related to the measurement signal communicated to the control system by the chest compression sensor.
